●Instructions
●Lecture
Week 1, 2 and 3 :
Honestly I couldn't attend for 3 weeks classes because I got technical
issue with
Taylor's Microsoft account. So, I just tried to catch up with 3D
Modeling fundamental
learning in Japanese as well with some website and youtube.
Figure1.1 The Beginner Tutorial of Blender in YouTube
The Blender screen is made up of five windows. Specifically, they are
the following
windows.
- Info window
- 3D View window
- Timeline window
- Outliner window
- Properties window
Figure1.2 The screenshot of Info window
The part of the Info window with menus such as 'File', 'Edit',
'Render' and 'Window' is
called the Info window. The Info window is also called the Information window.
Simply put, it is where you make basic settings for Blender. In
addition to that, you
can also use the Info window when rendering 3D models, not to mention
file
operations, so it is a part you must use when modelling.
Figure1.3 The screenshot of 3D View window
–3D View window
In the centre of the screen is the 3D View window. It shows rectangular
objects,
cameras and lights. When creating modelling, the 3D View is mainly
used. The three
blue, green and red arrows in the centre of the object are 3D
cursors, which not
only indicate the XYZ direction, but also allow the object to rotate
and scale around
the 3D cursor. They are also very important parts of the object, as
they are created
at the position of the 3D cursor when a new object is created.
Figure1.4 The screenshot of Timline window
–Timeline window
At the bottom of the 3D View is the Timeline window. Timelines
are used when
animating objects. It is commonly used to set up a situation where,
for example,
"the character starts sitting at the first second and finishes in a
gymnastic sitting
position after 10 seconds" or "the character starts crossing a
traffic light at the
first second and finishes crossing at the 15th second". Objects can
be enlarged,
reduced or rotated, and actions can be expressed along a time
axis.
Figure1.5 The screenshot of Outliner window
–Outliner window
The Outliner window is located in the upper right-hand corner of the
initial screen,
where 'Collection', 'Camera', 'Cube' and 'Light' are displayed in a
tree view. This is a
convenient window where objects and other objects are organised and
structured,
making it easy to manipulate complex scenes.In the initial screen when you have
just launched your Blender project, only three objects are generated:
'Camera',
'Cube' and 'Light'. With so few objects, it is easy to instantly find
the object you
want to move in the 3D View. However, when it comes to serious modelling, it is not
unusual to have more than 100 objects. Also, it is necessary to set
up several
'Lights' and so on. If there are a lot of objects in the 3D View, it can be difficult
to
know where the object you want to move or rotate is. In such cases,
the Outliner
window is a convenient way to find the object you are looking for by
name and pick
it up!
Figure1.6 The screenshot of Properties window
–Properties window
The Properties window is a screen where objects can be positioned,
rotated and
scaled in detail. Objects can be moved, scaled and rotated with the mouse, but it
can be difficult to manipulate objects to the nearest 1 mm with the
mouse. The
Properties window can then be used to position objects in fine
detail. You can also
set up motion paths for use in animation production.
–Moving the viewpoint within the 3D view
There are three ways to move within the 3D view.
- Navigation
- Wheel button
- Numeric keypad
Each of these is explained in detail below.
–Navigation.
Navigation is located in the top left-hand corner of the 3D view.
There are five
menus to choose from: 'Projection Method', 'Camera Perspective',
'Move', 'Zoom'
and 'Rotate', which can be selected freely. The viewpoint can be
moved by clicking
and dragging.
Figure1.7 The screenshot of Navigation
–Wheel button
The mouse wheel button can be used to move the viewpoint in the 3D
view. The
wheel button is the button between the left and right mouse
clicks. By holding it
down and moving the mouse, you can move the viewpoint.
–How to manipulate objects
There are four main ways of manipulating objects: selection,
movement, rotation
and scaling.
Figure1.8 The screenshot of Selection
–Selection.
To select an object, click on the box selection from the left
toolbar. You can also
select an object by left-clicking on it and doing a
drag-and-drop
Figure1.9 The screenshot of Move
–Move.
When moving an object, select Move from the toolbar. You can
move an object to
any location by moving the mouse while continuing to click
on the centre of the
object.
Figure1.10 The screenshot of Rotation
–Rotation.
For rotation, also select 'Rotate' in the toolbar. As with
moving, moving the mouse
while holding the left mouse button down will rotate the
object.
Figure1.11 The screenshot of Zoom in/out
–Zoom in/out.
Select 'Zoom in/out' from the toolbar. Move the mouse
while holding down the left
mouse button to zoom in or out on the object.
Week 4 :
For this week, we're required to make some objects such as leaf
with tutorial how to
create the shape in 3D Blender. For me, it was really difficult to
catch up with, so I also
tried to see some website and youtube in Japanese in order to
understand and utilize
the skills. Also I just asked some question to sir and decided to
finish the exercise
until this weekend.
Figure 2.1 The tutorial how to create the leaf
Figure 2.2 The tutorial how to use Lattice tool
Week 5 :
In this week, we required to use shortcut key of Blender to create some smoothly.
Also we could learn new tool to explore it with creating the Coca Cola pet bottle in
Blender.
Selection
Common to object mode and edit mode
Select all 'A'.
Invert selection 'Ctrl+I'.
Temporarily hide [H].
Hide and redisplay hidden items 'Alt+H'.
Selection type
Switching "W"
Pressing W switches the selection method in the following order: long-press, box,
circle and lasso.
Long-press selection 'Shift + Space + W'
Click to select, drag to move the selection.
Box selection 'Shift + space + B'.
Drag to draw a rectangle and select a range.
Circle selection 'Shift + Space + C’
Drag to select vertices, edges or faces.
You can change the size of the circle with the radius value in the header.
Lasso selection 'Shift + Space + L'.
Drag to draw a line and select what is within the range.
All selected "A" All deselected "A→A"
Movement "G".
You can move the cursor by moving it.
Rotation 'R'.
Allows rotation around the viewpoint centre.
Scaling "S".
After pressing the Transform key, you can transform by pressing the Coordinate
key to specify the coordinate axes. If you are before a decision, you can switch
between XYZ by inputting XYZ in succession.
Specifying axes (press twice to local)
Movement "G→X/Z/Y"
Scaling "S→X/Y/Z"
Numerical values can also be entered after specifying an axis.
Rotate 90° in Y direction "R→Y→45".
Difference between Delete and Dissolve
Delete erases all elements adjacent to the selected one, whereas Dissolve erases
only the selected one and tries to leave other elements.
Delete 'X'.
In object mode, you can delete selected objects. In edit mode, you can delete
"selected vertices, edges and faces", "edges and faces only" and "faces only". Note
that the way the object is deleted depends on how it is selected.
Dissolve vertex 'X'
You can dissolve vertices, edges, edges and faces only and faces.
Note that the way they are dissolved depends on how they are selected.
Creation
Adding objects 'Shift+A in object mode'.
Meshes, armatures, lights and cameras can also be added here. They can also be
created from the Add Header tab.
Add mesh 'Shift+A in edit mode'
Mesh can be added to the object being edited.
Duplicate.
Duplicate 'Shift+D'
In object mode, objects can be duplicated. In edit mode, a selection within an object
can be duplicated.
Link duplication 'Alt+D'
You can duplicate an object in object mode.
When you make edits in edit mode, the object becomes linked and all related
objects are edited in the same way.
Unlinking. Object data properties > Click on the number next to the name of the
mesh data.
Edit mesh
Extrude 'E'.
You can extrude from selected vertices, edges and faces.
Slice 'V'
Can be used for vertex and edge selection. The position of the cursor when
pressing V changes the way it is sliced.
Subdivide
The mesh can be subdivided.
Vertex context menu 'Right-click'
Edge menu 'Ctrl+E' Knife 'K'
Allows you to cut into the mesh.
Drag and drop from nothing
Click from nothing to nothing
Clicking on an edge
You can make a cut by
Right-click" to complete the cut and start again from a different location
Apply incision "Enter".
Split object 'P'.
In edit mode, the mesh can be split in selected areas, materials or structurally
separate parts.
Loop cut and slide 'Ctrl+R'
Allows you to insert a new edge that intersects the selected edge. You can
change the location of the cut with the cursor position and change the number
of cuts. Scroll to change the number of cuts. Once you have decided on the
location and number of cuts, press Enter to confirm. Move the cursor to
slide. Finally, click to decide.
Merge "M".
You can merge two or more selected vertices. From the merge menu.
'At centre', 'At cursor position', 'Bundle', 'At first selected vertex', 'At last selected
vertex', 'At distance'. You can select.
How to move the camera
The camera can be selected, moved and rotated.
After setting the camera viewpoint to 0, open the property shelf and select 'N'
Check View > View camera. You can manipulate the camera by moving the
viewpoint

Week 6 :
In this week, we got the brief introduction of hard surface modeling, project 1 and did
exercise 4 to learn how to create.
Concept, functions and notes on hard surface modelling.
Concept
Industrial product-like appearance
The convincing power of the product is increased if it has the look of a real industrial
product.
Chamfer to avoid damage or injury to the user
Appropriate chamfer width for each part
Thickness and thickness to prevent breakage and damage
Clean flat and curved surfaces
Smoothness where the flow of the surface changes
Constant regularity
Capture the intent of the shape and consider functionality
Make the shape convincing by making it look like it will actually function.
Create shapes that take into account functionality and the purpose of the part.
There is always a meaning to the shape of an artefact, such as the shape of a handle
for humans, a hole for ejecting something, a clasp for fastening the exterior, or the
classification of exterior parts in consideration of assembly.
Beautiful surfaces and highlights
Emphasis should be placed on clean highlights.
A clean surface will have clean highlights, and this beautiful surface will directly lead
to the attractiveness of the hard surface.
Check the surface using light, different angles and Matcap, which makes it easy to
see the highlights.
Wrinkles caused by triangles and other dirty topologies should be avoided.
Feel free to recreate it.
Although it is tempting to delete something once it has been created, polygon
modelling is often quicker and cleaner if it is re-created.
If you want to modify a particular part, it is easier to do so after deleting the
surroundings and edge loops.
Furthermore, it is more regular to use tools to re-create it, so the end result is
cleaner. Simple but effective.
●Exercise
Exercise 1 : MODELING FROM PRIMITIVES OBJECTS
1. Think of any object such as train, snowman, robot etc. that can be simplified as a combination of primitive shapes.
2. Sketch your idea for inspiration.
3. Using Blender, model the objects using primitive objects such as Sphere, Cylinder, Cube, Cone, etc.
4. Assign basic material to the objects. Using viewport shading technique, set the final look to make it presentable by manipulating the light and shadow appearance. Compose the object within the camera for final output by adjusting the right angle and frame.
5. Set the output size as 720p (1280 x 720). Use Viewport Render Image to render the final image and save as png format.
6. For submission, update the final image in your e-portfolio and upload a link on MYTIMES platform on the dedicated section.
7. Deadline of submission is on Week 3 by Monday 12th September 2022, 12pm.
– Examples
So for this exercise, I tried to download the Blender app in order to
create 3D objects at first.
Figure 1.1 the screenshot of the web page for downloading Blender app
After I download the app, I just tried to understand how to use this
with Youtube because I couldn't attend week1 and 2 session.
Figure 1.2 the youtube and playlist of tutorial
Anyway it's first time for me to create some 3D object that is why I'm
really excited. So for my exercise, I selected the shape I use for it
and the example photo for object image. I decided to create the crown.
Figure 1.3 the shape I selected
Honestly, I forgot to take some screenshot of the process that is why
I cannot show you some details but I tried to explore the skills of 3D
modeling object.

Figure 1.7 the screenshot from above
Also, I just searched how to export the data for jpg or something as
image.

Figure 1.9 the final design - pdf
Exercise 2 : NON-DESTRUCTIVE MODELING
1. Refer animals drawings that are showing basic shape construction from Cube, Sphere, Cylinder etc.
Example :
Figure 2.1 the examples of exercise
2. The model created should be in a low polygon with faceted appearance and segment as in the sample drawing. Use normal > auto smooth setting to get the smooth surface appearance of the low polygon model.
3. Assign basic material to the objects. Using viewport shading technique, set the final look to make it presentable by manipulating the light and shadow appearance. Compose the object within the camera for final output by adjusting the right angle and frame.
4. Set the output size as 720p (1280 x 720). Use Viewport Render Image to render the final image and save as png format.
5. For submission, update the final image in your e-portfolio and upload a link on MYTIMES platform on the dedicated section.
6. Deadline of submission is on Week 4 by Monday 19th September 2022, 12pm.

So for this exercise, I tried to create a cat modeling. First of
all, I selected the example image of cat and did sketch in Illustrator. After I finish sketching and exploring the way to create in Blender, I did it as well. It took a lot of time more than I expected. It was kind of difficult for me to utilize all tool, but I could enjoy improving the skill.

Exercise 3 : MODELING FROM CYLINDRICAL SHAPE
1. Think of any object made of cylindrical shape such as a plate,
bottle, bowl, glass etc.
2. Make a composition from multiple different objects as in the
example.
3. Get as much as references such as blueprint or images for selected
objects.
4. Model the object using a primitive cylinder by utilising modeling
tools like Extrude, Bevel, Inset and Loop Cut.Use Viewport rendering in
Blender for final output.
5. Output size is 1280 x 720 with png format.
6. Upload the final image and explanation on your e-portfolio and
update the link on TIMES platform as submission.
7. Submission by Monday, 3rd October 2022, 12pm.
Examples of the composition :
Figure 3.1 the examples
Figure 3.2 the tutorial of creating the wine glass in YouTube
Figure 3.3 the tutorial of creating the wine glass in YouTube
Figure 3.4 the tutorial of creating the plate in YouTube
Figure 3.5 the tutorial of creating the wine bottle in YouTube
So for this exercise, I prepared four images of wine glasses for creating the modeling in Blender. And then I tried to create these with these images.
Figure 3.6-9 the images for wine glass
Figure 3.10 the screenshot of process of creating a wine glass in Blender
Figure 3.11 the screenshot of process of creating a wine glass in Blender
After I finished creating the base shape, I tried to adjust some details such as putting the plate inside of glass to show it more clearly. Also I added the thickness of the glass because it was kind of too thin for glass. Finally I add the smooth tool as well.

Figure 3.13 the screenshot of process of creating a wine glass more thick
Figure 3.14 the screenshot of process of adjusting the details
Figure 3.15 the screenshot of process of making a wine glass smooth
And then I tried to create another wine glass in order to used to be create more quickly and better.

Figure 3.17 the screenshot of process of creating other wine glasses
Figure 3.18 the screenshot of process of creating other wine glasses
Figure 3.19 the screenshot of wine glasses
After I finish creating glasses, I added the material to show it more transparent and glass, so I adjust the metallic part, roughness and alpha. Also I put the background which I got from free HDRI site to express inside place.

●Feedback
Week 1,2 and 3 :
General feedback
So for these week, I just learned about 3D Modeling
with slides, some website and youtube. It's kind of
difficult for me to understand, but I could understand how
to use Blender app with exercises. I would like to catch
up with the lecture and improve the skills of 3D Modeling
as well.
Week 4 :
General feedback
For this week, I tried to finish the assignment of
exercise as soon as possible. Almost my brain was melted
although I could learn about the shape and method of
creating the non-destructive modeling.I'll try to create some stuff in Blender with speed. I need to practice a lots and used to be using the app.
Week 5 :
General feedback
I could explore the skill of Blender as well in this week. Especially, creating the wine glass and bottle, I got a lot of shortcut key and tool to show them real. It's still difficult and confusing for me to use clearly though.
Week 6 :
General feedback
In this week, I could learn about the way to put the texture from png or jpeg and so on. Also I got the brief introduction of project 1, so I just decided what stuff I'll do it.
●Reflections
>Experience
I got the experience that I could start using the 3D Modeling app, Blender with some lecture. I've never used this that is why I took a lot of time to utilize some tool of it. It was really good opportunity for me to create some 3D stuff within own skill, also I just wondered that I want to explore more and more then someday I'll create some art collection with this.
>Observations
From this experience, I supposed that it can be used anything which is for CM, Poster and animation although it also need to improve the quality of stuff.
>Findings
I got many shortcut key in Blender, so after week4, I could create some stuff very quickly. My favorite one is that "E", "S", "G" and "R" in edit mode. These are let me excited to explore the details part.
