Hello, my name is Na Yeon kyung, a webtoon artist
and an Invited Professor at Chungkang University's
Webtoon Cartoon Contents School, and I teach students classes
related to webtoon drawing
When you look at comics from the past
all the backgrounds were
what we call handmade, meaning artists would meticulously draw
lines one by one after going through various studies and preparations
However, most of the backgrounds in webtoons nowadays
are created using 3D programs
These images are then applied as backgrounds in webtoons
This may partly be because of the artist's desire to increase the density of their work
but it's also due to the nature of webtoons
Unlike print-focused black-and-white comics
webtoons are manuscript-based, often boasting rich colors based on a color palette
Also they have a consistent weekly deadline
and yearly increasing labor costs as well
This also reflects a shift from the traditional industry model
where individual artists took sole responsibility for their work
there's a transition towards a production-based system
similar to that of the gaming, animation, and film industries
Here, multiple individuals work in various positions
each responsible for their assigned tasks within a collaborative production framework
In such an industrially advanced field as webtoons
surely there are various positions
but a position that seems to be gaining prominence these days
I think is the SketchUp modeling part
The reason for that may be unlike directly drawing characters
you need to understand the space where those characters come to life
and evolving the design of that space
in a more clear and realistic manner through 3D programs
such a skill has grown comparable to drawings
That's why I believe SketchUp modeling has become one of the positions that's gaining attention
As I prepare for this lecture on the SketchUp program
I've been thinking about who the target audience for this lecture should be
I've prepared the lecture with the hope that aspiring webtoon artists
who are encountering this program for the first time
or webtoon artists who harbor vague fears about it
could benefit from this
Anyways I hope that after watching this lecture
you will have gained a better understanding and interest in SketchUp
Understanding the SketchUp Program
SketchUp is a software created by Trimble
for implementing interior architectural designs
One feature of this program is including a representation where
the designed shape has black lines outlining its contours
Upon seeing this, webtoon artists thought
that if they could model using this program
there would be no problem directly connecting it to the comic background
This led to the creation of the first example
seen in the webtoon "Romance Killer" by Kang Do-ha in 2007
After that, young artists
started using the SketchUp program
and sharing their experiences with it
This naturally led to SketchUp becoming one of the actively utilized
webtoon production programs among young artists
as they worked on webtoons
However, just like Photoshop, SketchUp wasn't originally designed for creating webtoons
Still, as more artists started using it and delved into studying its various functionalities
to make it more applicable for comics
and began utilizing it bit by bit as part of webtoon backgrounds
it gradually became established as one of the tools actively used by young artists in webtoon production
Now even the developer Trimble has started adding features
to facilitate modeling for webtoon background and it has allowed
SketchUp to move beyond its initial framework as a general architectural design implementation implementation program
and become applicable in various multimedia
arts fields such as webtoons, animation, and film
In this lecture, we'll briefly explore
creating models using SketchUp and extracting them
for use as webtoon backgrounds
color-correcting the extracted SketchUp images
and applying them as backgrounds
Additionally, we'll explain how to obtain information from various SketchUp modeling files
Please note that I am using a purchased version
instead of the subscription so the SketchUp program
shown in the lecture is the 2022 version of SketchUp
Before continuing the lecture
My lecture screen
will be set to MacOS environment, so those of you with WindowsOS
might be a bit unfamiliar with my screen
But the main page of Sketchup is pretty much the same
so you shouln't have too much difficulties with the lecture
Let's run the SketchUp program
When you launch SketchUp, the first thing you'll need to choose
is the environment in which you'll be working
If you look at the screen, you'll see that you can choose between two categories
"Simple" and "Architecture," allowing you to select your working environment accordingly
Among those options, you can select various units
such as meters, centimeters, millimeters, inches
and more for your working environment
As you can see, there are various options available for different environments
centimeters for architecture, meters for simple
inches for simple, and inches for architecture
The reason for the selection is that the person creating the model
needs to decide whether the modeling involves
small-sized props small-sized props
large spaces where people live
or move around
If you select millimeters as the unit
and aim to create a large space that people will enter
you'll have to manually convert all measurements
into millimeters for your work
which can be quite laborious
To avoid that, it's important to carefully consider the type of space
you're creating and adjust the environment accordingly
In addition the "Architecture" environment
does not include representations of
spaces high up like the sky
or low, flat spaces like the ground
Therefore, when extracting images, it's important to determine
whether a background representing the sky or ground is needed
This decision depends on whether you're modeling an indoor space
hich typically doesn't require such backgrounds, or an outdoor environment, where they may be necessary
This is another aspect that the person creating the model
needs to decide before starting a new project
Let's create a model in centimeters
When you select that you will find a vast expanse
with an endless horizon, with a random man standing
You see this man here
He is not really there
just for fun
He represents a human model with an average height
suitable for entering the expansive space you're creating
So you can make a door in comparison to him
or make windows and couches
When you create things like that
you can visibly see that a person this size could sit on this couch
or this person can go through the door
That man is there for those purposes
I would like to explain about the mouse beforehand
The SketchUp Program
uses the left click, right click
and you know the wheel in the middle
the wheel click is also used in modeling in SketchUp
If you do a left click
you can launch tool features
or select functions from the menu tab
So it is a regular click
you can select a tool or bring out a window from the menu
That is what the left click does
The right click
opens a window where you can see the details needed for modeling
Let's right click on this man
you will see a window like this
That is what the right click does
and if you scroll the wheel up or down
you can zoom in or zoom out on your work screen
wheel it up and it zooms in
wheel it down and it zooms out
Basically a zoom in and out
you can center it on this man
and it will zoom in around this man
or you can center it elsewhere and it will zoom there
So accurately position the mouse cursor
to the area you want to zoom
zoom in on by using the mouse wheel to scroll up
or down for zooming out
This is the way I recommend
Lastly if you click the wheel and drag
It will allow you to view various angles and perspectives of the model
Like this
To view the model in this manner
is a feature called Orbit
I will comeback to explain that when we get to the toolbox
but first clicking the wheel
and dragging it
you can see the Orbit
That is what clicking the wheel is for
To understand the mouse functions
let's click, right-click
and try scrolling or pressing the wheel
clicking
click the Select tool, try right clicking it
try zooming in and out
and try going in a Orbit state
You would need to
get used to this to fully use SketchUp Program
Also a reminder
If you have used Photoshop or Clip Studio to make webtoons
you would naturally have
a habit of drawing lines by dragging the mouse
What I mean by
dragging the mouse to draw
for example if you use a tablet
When you press the pen on the screen and move it, you can draw lines like this
and when you release it
just like releasing a button after clicking
the line has been fully drawn
This analogy might help you understand
In SketchUp, you would almost never
draw lines by dragging
Most modeling programs
is pretty weak to freehand drawing
so you can mostly utilize
simple actions like clicking and moving to achieve your tasks
As I mentioned earlier
this is a program for interior architectural designs
So if you would approach it like a drawing program
It might be difficut
So what should we do
As an example, let's say I draw
a square using the drawing tool
click once and keep your finger off the button while moving
an area where the line will be automatically drawn is formed
then if you click again where you want to draw the line
click and click again
lift, move and click
move and click again
now you have a squre like this
this is how it works
If you keep dragging it will only hurt your hand
and doesn't really move in a way you would want
so it will be difficult
So click, lift, and move
and click again, and that will be your best move
I would like to explain about the program SketchUp
To the left there is the Tool Set
to make models with
I will go into details about this toolset
About half of the tools in the set is
made for architectural designs rather than webtoons
So I will disregard those here and explain the rest
For example this tape measure
hex protractor things like these
will not be necessary
While it might be useful to know this information
but it's generally not necessary
or typical modeling tasks
First the tool with the black arrow
The one I selected here
This is the Selection Tool
Because SketchUp is a Modeling program
it is different from other drawing programs
It has a feature that allows you to select implemented lines or faces
and help create shapes for other forms
you can use the selection tool to utilize them
And the tool next to the arrow with a hook drawn next to it
unlike the usual selection tool
you can select an area differently
If the original Selection tool
is for selecting lines or planes
The Lasso Selection Tool
whether lines or faces
allows you to wrap around the area you want to select like a lasso
selecting everything within the loop
The Paint Bucket below that
It would be a fill in tool in typical drawing programs
but in SketchUp you can
easily fill shapes with patterns
such as textures or materials
That is what that is for
the pink rectangular icon is the Eraser tool
It only erases lines that are implemented in 3D
It does not erase faces
However if any part of an implemented face
loses a line, the face disappears
Therefore, while you can't directly erase faces
understand that a face disappears when even one of its lines is erased
And the tool below it is called "Component," which allows you
to view the created model as a unique configuration or setting
If you click it
A window like this pops up, allowing you to create component elements
If you click the man
and look in the components window
This is how the Customer Information Manager is handled in SketchUp
with settings written like thi
You can think of these as buttons for inputting such information
And the tool next to it called "Tag"
allows you to insert tags that provide guidance on various architectural products
such as wallpaper, flooring
doors, windows, etc
which are created when designing architecture interiors
You could consider this feature not particularly essential
for modeling in webtoon production
These are the more commonly used tools
Next will be for drawing
they will be tools from drawing
the Pencil tool draws straight lines
I showed you earlier
It only draws straight lines
cannot draw curves
and on the other side
This is a tool for drawing freehand lines allowing you to draw
not only straight lines but also freehand lines
So you can draw
lines like this
The square at the bottom
The Square
allows you to draw retangular shapes
If pencils only draw straight lines
the square can connect the lines and make a rectangular figure
but if you use this tool
You wouldn't have to go back and forth to click 4 times
but make a rectangle at one cue
By doing this, moving, and pulling you can create a rectangle like this all at once
Next to the squre tool
There is a curve and a squre inside
this tool allows you to rotate
first if you've made this rectangle
you can use this tool
to make it like this
and the circle at the bottom
is literally to draw circles
And the tool next to it, with jagged edges
allows you to create polygons with 8 sides, 6 sides, 12 sides, and so on
The icons below are all tools for drawing curved arcs
The first tool, where only the curved arc is visible, is for drawing arcs
the one connected by two points is for drawing 2.5D arcs
You click on two points and then drag to determine the direction to pull out the curve
For example, with arcs like this, rotating allows you to draw the arc from
he second point onward
with the first point serving as the pivot
And with the two-point arc you click once
then click another point and drag
to draw the arc in that shape
a semi circle like arc is drawn. That is a two point arc
For the 3 point arc you need to click 3 times
inputting once, twice, or three times
and you can determine what kind of arc you draw
like this
you have a arc like this
you see, so this is what the
3 point arc tool does
the last one is
for drawing fan shapes
You might think that it is
similar to the one point arc, but if you look closely
you can see the fan-like face
the 1 point arc simply draws the curve
its a curved line
but the fan tool draws a fan structure
and creates a face
that is what the fan tool is about
These are the drawing tools
Now
this tool here is used to
create the shapes of the modeling
First if the Move tool
For example if you have a
square drawn, you can use the move tool
to move the square
This is what that is
There are various methods for using this tool
but it's good to know that it's a tool for moving shapes
next to that
is a tool commonly referred to as Push or Pull
It creates three-dimensional shapes from flat surfaces
Withi this tool
you can mange to do most of the modeling
So we will make the first rectangle here
and using push and pull to the top and
we just made it 3D
If you say
you wanted this area to go more inside
then you can push and pull it
and make something like this
you see
this is a tool for modeling gradually
using these kind of functions
the rotating arrow on the bottom is the Rotate tool
If you go back to
the hexahedron made with Push and Pull
and wanted to rotated it
We can rotate to twist the figure like this
Or if you want to rotate this as a whole
first select around the whole thing
and rotating it can rotate the whole figure
So this is the Rotate tool
The next tool is called the Follow tool
You can think of this tool to be used
hen you need to create a shape that follows and wraps around another shape
To give an appropriate example
I'll create a shape I want to be wrapped around
and to make it more dimesion
I will
shave it a bit
Now let's wrap this around
use the follow tool to select
Select the Follow tool
and if you make the following path
like this
you see this being wrapped around
If you come all the way to the front
You can see that it's created in a shape that wraps around like thsi
If you would have to make this with Push and Pull
It would be difficult because you would have to do all 4 sides
but using the Follow tool
This is fairly easy to do all around
So this was the follow tool
The fifth tool is called Scale
Scale has the function to increase or decrease
in a certain ratio, flatten, or elongate vertically
It can bee seen as somewhat similar to
the Transform tool in Photoshop
For example if you select this and click Scale
you see an adjustment bar
When you tilt the control bar like this, it becomes elongated
pulling it vertically increases its height
and pressing it diagonally results
in scaling up or down like this
So the Scale tool has these functions
The last one on the right is Offset
With this Offset you can select a regular line
and it allows you to draw lines extending outward or inward parallel to the line
For example when supported by a line like this
the shape is created in a way supported by the line
you see
If you then click and pull inwards
The shape is created with lines drawn parallel to all sides, fitting accordingly
you can also drag this outside
and keep drawing lines like that
So, when creating something like a frame, window, or door
where the thickness needs to be consistent on all sides
it's easier to make using the offset tool to maintain consistent thickness
So these 6 tools are
what makes the drawings more dimensional
And the other extra tools are really not very helpful in webtoon making
So I will not go into the details
Now if you look to the right you can find a few windows open
The tag is open as well
I will explain these one by one
From the top, this is a feature within a window that allows you to create a webtoon background
specifying the layout to fit the required scene
and then saving it as a single scene
Given the nature of the task where you need to rotate a single background
to fit various angles and extract scenes
organizing and saving backgrounds that match each panel in this window called Scene
will help you keep things organized and easily usable without confusion
The next window is the Component window
I have mentioned this earlier
If you click using this tool
On the right side, there's a component window where you can inspect the settings
and attributes of the models saved as components
These components might not be abundant for you to see right now
but when you purchase or obtain models externally
there will likely be many of these components saved
So If you needed to edit that
you can use this window
The third one is the Shadow settings
This shadow settings allows you to make modelings more realistic
by allowing you to adjust a certain level of brightness and darkness
You can use this to represent shadows at daylight or night time
shadows in Winter or Summer
and so on
If you click the six-sided icon on the left
you can see the shadow forming
the person also has a shadow
You can see the shadow effects here
and using these, you can easily extract shadows and other details related to three-dimensional aspects
without having to input them manually into the webtoon background
Just extract them according to the SketchUp modeling
and you'll have shadows and other details readily available
If you turn it off you will not see the shadows
The reason I turn this off is
The shadow feature utilizes the graphic acceleration engine
which can strain the computer's resources depending on its specifications
herefore, it's recommended to turn off shadows while working or modeling
and only turn it on to extract the picture
and it will be more usful
Next is Style
It is a window where you can adjust various settings to create backgrounds for webtoons
In this window you can experiment with changing the outline of the modeling corresponding to the pen lines
You can also convert color models into a
black-and-white comic style by removing colors
So you can experiment with styles here
This was the explanation related to SketchUp
Making a table using SketchUp
Now we will spend some time doing simple modeling project to familiarize ourself with SketchUp
We will make a rectangular table
First let's create a new building by the centimeter unit
We will create a new model of architecture centimeter by centimeter
We have made a new modeling
First we will use the Rectagle tool to
make a rectangle 160 wide and 80cm high
To do this you can select the rectangle tool and make a dot in the center
and move the mouse to make a rectangle
now you enter the numbers 160 and 80
You can see that a square 160cm wide and 80cm tall is automatically created
To create the desk top like this, use the push and drag tool
and we will raise about 3cm
After clicking and checking this push and pull
enter the number 3 and press enter to see it be raised
Do not drag the click. You need to click lift and move
Now using the select tool to select the rectangle at the top
This time, we will use the offset tool to create two rectangles inside
If you select the transformation and pull it inward, a small rectangles like this will be formed
we will bring it 6cm inwards
Select the smaller rectangle
Next, I will use the offset tool again to create another shape inside
to create a thicker shape, this time I will make it 2cm thick
press 2 and enter and now you have a rectangle with a bit a thickness formed
Now we want to create legs at the four corners
To do this we will make the smallest square figure
at the four corners
use the rectangle tool to make a square
After marking the endpoint and confirming it made a square
enter 4 for width and length
Now you have small square
Repeat these steps for the other 3 corners
When you press the wheel button while moving, the angle moves like this
but if you press shift and move the icon changes to a handle
then you can move around like this
Now that we moved
enter 4 width and length again
You can see we have made all the squares
We will pull these legs out using Push and Pull
We should select the small square using the push and pull tool
If you have trouble selecting it use the selection tool arrow to select the square
The display will gradually look like this, and when this happens, it has been selected
now use the push and pull too to pull it upwards
It will get pulled out like this
we will set the height to 60 and press enter
repeat the process to the other 3 squares
If you double click, you can see they are the same height
Double click all 3 squares
Double click again
Now we have created the legs of the table
The outer border wraps around a rectangle enclosing a rectangle
In this state when it comes to a table
the legs may not gain support and may wobble so we wrap the border to provide support
We will use push and pull on this as well with the height of 7cm
Enter 7
Now we have support covering the 4 legs
Now we have created a table that is upside down
To flip this to a normal state
Let's us the lasso tool to select the whole table
After you have selected, press the Edit tab
you'll see a window at the bottom indicating "Selected 124 elements"
If nothing is selected, it will say "None selected."
What to do with all the elements
If you press the Flip criteria
we have three directions: red green and blue
Since we will be flipping upside down, we will select the blue direction
If you select it, you can see we have manage to make a flipped table
Now that everything is selected we want to add some woodiness
we will use the paint bucket
and fill in colors
Generally when you select the paint bucket you will have a new windows called colors
You can literally think of this color as just a window that expresses the color
click on the color name, you will see several items on the list
From that list, select wood
Then we see all these different colors and textures
that remind us of woods
I will pick the cherry color
If you select your color and click the table
the color/texture will be filled in to whatever is selected
now use the black arrow and click an empty space and you've unselected
Now you can see the table we created
We have created a rectangular table
SketchUp Modeling Extraction and Image Correction
We have done some modeling with SketchUp
How do you feel about it?
You may be wondering how to create a whole space
when modeling even the simplest form is so difficult
That is why we have something like this
It is a site called Acon 3D
This website serves as a space where many webtoon artists
can purchase the rights to use models created in SketchUp
for their works at an affordable price
If you go to 3D asset and press category
You can see that many artists create SketchUp models
in various forms and sell the rights to use them here
You can easily download and attain the modelings here
Nowadays with time being of the essence for many artists, they can easily obtain high-quality backgrounds
through searches without having to individually create each model
As a result the utilization of SketchUp in webtoon drawing has become even more prominent
This time we will open a sketch downloaded from Acon3D
and make a webtoon background
First, open the downloaded file
We see this made up sketch. Use the wheel to go around
and Shift the wheel to move around with the handle
You move the camera around like this
to create the scene's compositio
Once the composition is complete like this go the Scene window on the right
click the icon and assign each scene
We do this because
even after we move around using the wheel
after the scene has been saved
if you double click the assigned scene
It goes back to the angle you set them in
So you can save this scene
If you're creating scenes for a webtoon using SketchUp
you'll create multiple scenes tailored to fit the webtoon
If you've created multiple scenes, you'll need to extract them as images
for a better quality project
We will extract images in three steps
line drawing, shadowing and texturing
First here is how to extract images in the line drawing step
To do this, go to the style window
the third one on the list is called hidden lines
or it's described as silver line
press this icon
Now you see there is only shadows
and there are no colors here
only the black lines
shadows may interfere with work
so turn off the shadow button
and save this black and white scene
to the Scene window by pressing the Plus button
We have saved the line drawing step
Second we will save the shadows
We will have to turn back on the shadow
Now the lines interfere so we need to get rid of them
Right now it is in Siver line state
Use the Style window's Edit tab
If you uncheck what is labled as
Edges, which is selected now
Now you have an empty space
Now press the shadow button here
and we'll save it like that
Press the Plus button in the Scene window
and save the shadow as a scene
We have the shadows now
The last step is textures
For textures, you can click the scene you initially specified
or go to the style window and
select the default style
and It comes back to the origial state
What to be mindful of here
people tend to turn off the shadow when saving
Then we have the difference in brightness here
So you need to turn on the shadow
and when it's turned on
go to aux tools
Click this window once
It says to display a secondary selection window
If you click this
You can adjust the brightness and darkness at the bottom
Make the brightness to 0
and the darkness to 100%
you see there is no shadow that is showing
you will be left with only the default texture
You would need to save
this one as texture form
so we do not need the lines
Go to edit tab
Turn off faces, edges, and profiles
and there is no black lines
but the other textures
you can see it like this
Now go to the scene window and press plus
to save as a new scene
We have made new images of three things now
lines, shadows and texture
We need to extract them as images now
To do that
Let's save the lines first
to do this
go to file tab, export and select 2D graphic
and a new window pops up
choose where you want to save this
make sure it is the right folder you want
and for file type
choose png file to save the invisible parts
jpg or gif files
the empty spaces does not save as invisible
so make sure to use png file
to save the invisible parts
now press the option button to the right
If "Use view size" is checked
you won't be able to adjust
the resolution you have in mind
make sure that is unchecked
I usually set it to about 4000 pixels
then it automatically resizes
the height and width ratio
And the line scale multiplier is set to 2
but I usually set it to around 4 by default
set the line scale multiplier to 4 like this
the line scale multiplier is
When extracting the image with the black lines
The bigger the image is to extract
the thickness tends to decrease
So this basically adjusts the thickness of the lines
Now click ok and export
since it's the pen lines
I will name it as 001 followed by
the letter P for pen
the Lines have been saved
Do the same with shadows and go to file, export and 2D graphic
We have edited all the options earlier
We will just change the name to 001S for shadow
Now the texture
File, export, 2D graphic
We will save this as 001T for texture
Now we have saved all three files
Now we will open these images using Clip Studio
Open Clip Studio
bring the three png files here
See here we have all
three files
texture, shadow and lines
You stack each one of these created images layer by layer, dividing them into layers
The very bottom needs to be texture
then the shadow
you see the shadow is shown as gray
That is normal for shadows to be this color
we will use the paint bucket to fill them black
choose black
uncheck pixel selection
and turn off zoom
then you can fill exactly the grey areas
Like this
after doing this, you should redo it again so that it doesn't interfere with your work later on
Select the black
Now that I see the window area should be invisible
but is set to white
what to do here
to take the white out go to Edit
When you convert brightness to opacity
all white parts become fully transparent
If you have done that
Select all and copy
and paste on top of the texture file
Now we have the shadow on top of it
as you see here
now the pen lines
this file also has a white background
and outside the window is invisible
Also go into the edit tab
convert brightness to opacity
Select all
and past it on top of the texture and shadow
So first is the pen lines and then the shadow
and the last one should be texture
Here lock the transparent pixels for the pen lines
Click the "Lock transparent pixels" button to lock the transparent pixels
so that coloring won't affect areas other than the pen lines
And for the shadows, reduce the opacity to around 70%
This will give you the shadow effect similar to what you see in the default SketchUp screen
but since it is black-based
if you feel like it is too dark to your liking
go to layer properties
click layer color
If you click on the blue color box, represented by the blue color
you have the color settings
from here, you can choose the tone you want for the shadows
to set the atmosphere you desire
I prefer a yellow tinted shadow
By doing this, the shadows will be expressed as if they're reflecting the color they're cast upon
It seems a bit bright so I will make it darker
I will make it this dark
Now compared to the grey undertone
we have a brighter background
This is not the end
We need to adjust few more things in here
Since the shadows indicating incoming light
et's do some post-processing to enhance
the sense of light coming in
Make a new layer to the very top
and change the propereties to Screen
again, change the opacity to 70%
Here
The shadows are there, but the areas where the light is coming in from outside the window aren't clearly visible
So for the areas where the light is coming in through the window
to give a yellowish light effect
select the soft airbrush tool
and apply it like this
Then we have
represented the lights coming in
Now we have the lights coming in
and the shadows
You can add some characters and adjust
the post-processing accordingly to fit them
but as far as backgrounds go
you need to think about the finished product
So only do a little bit of editing
It would be ideal to
apply post-processing at 100% for the entire scene
after you composite the characteres
Now we have extracted the webtoon image
separated it into pen lines, shadows, and textures
added lighting effects
and did basic post-processing
up to this point
Up to this point, we've explored SketchUp
a program necessary for webtoon production
We've had a brief but hands-on experience with modeling
downloading modeled backgrounds and directly placing them
and adjusting post-processing
to match the atmosphere of the webtoon.
Unlike in other fields, SketchUp background modeling has
gained prominence as one of the
most active items in the webtoon industry
thanks to the emergence of sites like "Aicon,"
where various SketchUp models are sold
As a result, many people in the webtoon production industry
are using SketchUp, and there's also a growing number
of professionals who make a living
as dedicated webtoon-specific SketchUp modeling builders
While SketchUp may seem daunting at first
due to its association with 3D
but you'll find that it's surprisingly easy to use
and there aren't many
significant challenges in handling it
Unlike other 3D programs SketchUp is straightforward
making it less complex to use
I hope this may lecture dispel
any fears you might have towards Sketch up
provide you with the confidence to study calmly
fostering a sense of empowerment towards learning SketchUp
This is the end of the lecture
Thank you for listening
WRAP UP Understanding SketchUp Program SketchUp modeling program Implementation program for interior architectural designs created in 'Trumble' SketchUp can be used in various multimedia fields
The reasons for the popularity of SketchUp modeling Enhances understanding of spaces where characters interact Clearly and realistically depicts spatial design and composition
Choosing the working environment for SketchUp modeling You can select simple architecture, mm, cm, m, or in Implement the working environment by selecting the size and shape of the model
Using SketchUp to create a table Create a Table Select New Model in architecture, cm Draw a rectangle 160cm x 80cm high
Use the Push/Pull tool to raise the tabletop by 3cm Using the offset tool to create a 6cm square inside the desk Using the offset tool to create a 2cm square inside the 6cm square
Click on the inner square, then create a 4cm x 4cm square using each corner as a reference point Create a 4cm x 4cm square at every corner
Select square, use push/pull tool to raise it 60cm Use push/pull tool to raise the legs' supports by 7cm Use the select tool to select the entire table
Go to the Edit tab, select "124 elements" for symmetry, and choose the blue direction Click the paint bucket tool, then select "wood" from the color window
Extracting and editing SketchUp modeling Extract scenes from SketchUp modeling Select "Export" then "2D Graphic" in the file menu Choose the storage location Select the .png format
Uncheck "Use view size" and enter the desired resolution value Adjust the thickness of pen lines using the line scale factor Enter the file name and click 'Export.' Edit and adjust the extracted image as needed
Layer-created image to make high-quality background Duplicate shadows by selecting all and overlaying them on the texture image Duplicate pen lines by selecting all and overlaying them on texture shadow image
To express light from the window, add a lighting effect with an airbrush Adjust only part of the background, and then examine how it fits with the character
