LECTURE

Week 1 :

We have a brief introduction to the development of animation so that we get the general idea of what to expect in the following weeks. Design students are encourage to upload our final work in Behance/ Artstation and insert the link of the Blogspot after each post.

Week 2 :

In today's class, we were introduced to a powerful software, Blender. Blender is a free and open-source 3D computer graphics software tool set used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, virtual reality, and, formerly, video games.

Mr. Kamal guided us the basic interface of Blender and some shortcut keys to remember.

Week 3:

We learned about the viewport shading and rendering, as well as the adjustment of camera angle and frame to export the object as an image.

For Eevee, need to change the blend mode to Alpha Blend to see the transparency.

For Cycle, the emission light on shadow can be viewed.

Week 11:

Texture and Material

Go to the "dot" beside base color, click "Image Texture" and "Open" to upload the image texture downloaded from the Internet.

Ctrl + J to join the points. Right click "mark seam" Click U to unwrap the organic shape.

INSTRUCTIONS

Exercise 1 : Model Blocking of Primitive Objects

Primitive Shapes

In Week 2 and 3, we learned to build objects from primitive shapes like plane, sphere, cube, cylinder and monkey. We get to familiar with the shortcut keys and the user interface of the blender.

We have made snowmen and fruits on table in Week 2.

Figure 2.1, Snowmen, Week 2 (5/9/2022)

Figure 2.2, Fruits on table, Week 2 (5/9/2022)

The next week we learned to add color to the shapes. We also learned to change the camera angle view based on the rule of thirds.

Figure 2.3, Changing camera angle view, Week 3 (12/9/2022)

Then, we learnt to change the lighting setting. There are various material presets available.

Exercise 2 : Non-destructive Modeling

In this exercise, we are to make use of the modifier tools to construct an animal. We only use basic primitive shapes to build the model in a low polygon with faceted appearance.

The animal I have chosen is alpaca.

Figure 2.8, Alpaca, Week 4 (25/9/2022)

Figure 2.9, Alpaca, Week 4 (25/9/2022)

I started to build its body by first inserting a cube. Then, I use Array to create 3 identical shapes. To modify its shape, I added a Lattice, the deformation cage around the shapes.

Figure 3.1, Body, Week 4 (25/9/2022)

I tried to make its neck by using curve tool. However, the results was not satisfying and so, I replaced it with normal cube and deformed using Lattice.

Figure 3.2, Neck, Week 4 (25/9/2022)

For the tail, I used cone shape and again, applied Lattice tool to bend the tail.

Figure 3.3, Tail, Week 4 (25/9/2022)

Figure 3.4, Head, Week 4 (25/9/2022)

I also added a cube for the ear and used Bend and Taper from Simple Deform. Then, I duplicated the ear and mirrored it to Y-axis.

Figure 3.5, Ears, Week 4 (25/9/2022)

Figure 3.6, Ears, Week 4 (25/9/2022)

The next step was to create the legs. The steps of creating the forelimbs and back limbs are similar.

Figure 3.7, Limbs, Week 4 (25/9/2022)

...and here is the final construction of the alpaca.

Figure 3.8, Ta-da, Week 4 (25/9/2022)

But it's not yet done, the last step is to add material and export it in multiple angles.

Exercise 3 : Modeling from Cylindrical Shape

In this exercise, we are tasked to model the objects using a primitive cylinder by utilizing modeling tools like Extrude, Bevel, Inset and Loop Cut.

Extrude:

Extrude is a great tool to extend the face/vertices. I used this tool to model the objects by pressing "E".

Figure 5.1, Extrude tool, Week 5 (2/10/2022)

Loop cut:

The loop cut tool creates a loop of one or more edges along a ring of quad faces. I pressed Ctrl+R, and hovered the selected edges, and scrolled the mouse wheel to change the number of cuts and click to confirm.

Figure 5.2, Extrude tool, Week 5 (2/10/2022)

Bevel:

The Bevel tool allows me to create chamfered or rounded corners on geometry. I have applied this tool in the edge of the bowl by pressing Ctrl + B.

Figure 5.3, Bevel tool, Week 5 (2/10/2022)

Inset:

I first selected the faces of the cup and then double pressed "I" to inset each individual faces.

Exercise 4 : Hard Surface Modeling

Hard surface modeling is a technique used for creating 3D models with smooth and solid surfaces.

We are taught to model Karambit using polygon tools. The reference image is provided by the lecturer.

Figure 6.2, Karambit, Week 6 (3/10/2022)

To create the hollow ring

Select the two vertices and press "J" to connect vertex path. // Go to edit mode, vertex and select "connect vertex path".

Figure 6.3, Connect vertex path, Week 6 (3/10/2022)

Alternative way:

Remove all the faces except the front face. Use inset and extrude.

*Item/mean crease to edit crease

The rest of the knife is made by using extrude and rotate tool to form the bending edge. Knife tool is utilised to subdivide the geometry. In this case, it is to let the crease more obvious.
