Weekly Lectures
Week 1
This is the first week of class. Mr. Kamal briefed us on the work that we will be working on throughout the semester. The assessment consists of exercises, project 1,2 and a final project. We were then learn about the behind the scenes of 3D animation.


We had a tutorial session to learn the basics of the 3d modelling software we will be using throughout the semester, Blender. We were given the list of introduction to Blender syllabus to know what we would have to know to be able to better understand the software.
Blender Introduction Syllabus
A lot of shortcut keys to learn and remember.

Quad view = ctrl + alt + Q, 
press N for side bar
Press T to bring out the left tool box
click move tool to move object
Alt + G to reset position +(press x, y, z) 
Alt + R to reset rotation +(press x, y, z) 
Press S for scaling


Week 2
It's a public holiday on this day.



Week 3
This week's lecture, Mr Kamal lectured us on the modelling techniques. There's a few types of modelling techniques that we can use but mainly we focus on using polygonal modelling technique consist of using the polygon shapes availabe on Blender. There's a few other techniques like nurbs and sculpthing.

We learn about switching from object mode to edit mode. In object mode, we can do the basic stuffs like move, rotate,scale and transform. Edit mode makes things more advanced consisting the basic stuffs from object mode with additional tools like extrude, inset, bevel, loopcut, knife and more.


Mr Kamal guide us through learning the basic component of the polygon shape.
1. Vertex / Vertices
2. Edges
3. Faces

He also lectured us on symmetrical modelling which is like folding origamis. He gave us a formula for using the technique with a cylindrical shape.
n+4=x

Example: 8+4=12... 12+4=16... etc.

Press I for inset 
Press E to extrude 
We can press S to scale on the extruded part
ALT + click to select everything 
Press look up in edit mode and scale mutiple times to make curved line
For a curve smooth side, we can you bevel, then go to EDGES  on top, Bevel edges and setting below to adjust many section you want, the width as well 
ctrl + B to bevel edges 
ctrl + 1, ctrl + 2, ctrl+3 to change into a higher polygon
press e, right click to cancel the press s and move up  
to add thickness you can add solidify at the modifier side and add thickness


Week 4
This week we learn about hard surface modelling by making a car today.
Ctrl + B to bevel 
Press J to connect vertex path (vertex - connect vertex path)
to bevel evenly, go to object mode - selct object - apply - scale (all the scaling should be on 1.0) 
Shift + alt to select the edge to select horizontal.
Colour: Select edges - right click - mark saem - material - +new - colour - assign 
Ctrl +L to select the whole MARK SEAM


Week 6
This week we did a karambit model with blueprint provided as a guide.


We learnt to use the bool tool that has the mechanism to alter a combination of 2 shapes in any way with the options listed: differences, union, intersect and slice.

Bool tool: Ctrl + Shift + B
Edge > Edge bridge loops
Select both edges and press F (Faces)



Exercises
Exercise 1 - Primitive Modelling
On week 1, we work on making any objects such as train, snowman, robot etc. that can be simplified as a combination of primitive shapes such as Sphere, Cylinder, Cube, Cone, etc. Use transformation tools to manipulate the object and you may use modifier tools to deform the model.

Exercise 2 - Cylindrical Modelling
On this exercise, we are required to made a cylindrical shape object such as a plate, bottle, bowl, glass etc then make a composition from the objects. Model the object using a primitive cylinder by utilising modeling tools like Extrude, Bevel, Inset and Loop Cut. Apply a smooth modifier and adjust the sharpness or smoothness of the corner using various techniques.

I chose to make wine glasses and bottles as I could come up with an insane composition for it.

Exercise 3 - Box Modelling
On this exercise, we are required to made an object made of box shape such as an electronic device, vehicle, furniture etc. Model the object using a primitive Cube by utilising modeling tools that you have learned in class using box modeling techniques. You are allowed to combine with other shapes like cylinders, spheres etc but the dominant shape must be in a box. Apply basic material and colour.


I chose to make a bed as it is mainly a cube shaped. Then, I found a canopy bed so I figured to do that as it is interesting instead of just having just a bed.

Failed attempts in making blanket using physics
This process of following the tutorial to make the blanket realistic was giving me insane stress so I opted to do the easy way which is by making it with another shape then transforming it.

Exercise 4 : Organic Modelling
For exercise 4, we had to download the karambit image as blueprint and model it using organic modeling techniques and tools that we have learnt previously in class. We should apply basic material and colour at the end. 

Requirements:
Output size: 720p (1280 x 720)
Format: .png (render final image using Viewport Render Image) 
Submission 1: (Rendering)
Final render solid without wireframe
Final render solid with wireframe

Submission 2: 
E-portfolio blog link (format *.doc)
Blender file


For this exercise, we first did a tutorial on making a karambit in class with Mr Kamal's guidance. It was quite easy to understand on how to make it with a step by step guidance. I reattempted a few times on the making of it as I was not really satisfied with it. I made sure to check and fix my wireframes to make it look cleaner.

Mr Kamal reminded us to clean up the wireframe as the scaling of the edges could make the wireframe look wonky in a way. It was interesting to use the bool tool to do the ring part as it makes things way easier.


I added on details for the knife to make it more realistic like the blueprint given by making screws and the rubber part of the handle. The screws consist of uniting 2 shapes to form a plus (+) shape to then be combined with an oval.



I let Mr Kamal check my model and he suggested on making the knife look sharper by using subdivision (Ctrl + numkey 1 or 2). He also told us to put edge loops on the ring part to have a cleaner line when it gets rendered as the edge loops serve as a support for the edges in the model.


Final Exercise 4: Organic Modeling




Feedbacks
Week 6 / Exercise 3
Specific Feedbacks:
Could remake the pillow by using the method shown by Mr Kamal. Could use a better camera angle and put a background to cover the empty spaces behind the model to focus on the object better without the distraction of the blender background.


Week 7 / Exercise 4
Specific Feedbacks:
Make the tip sharper by adding moore division so the knife edge looks smoother. Good camera angle and backdrop with the use of lighting to cast the shadow. Everything else is okay.


Reflection
Exercise 1: Primitive Modeling
This exercise was fun and not that hard to do as it requires for us to just make a model with the basic shapes in Blender, basically allowing us to understand the basics on using shapes to model. This task requires us to sketch as it is used to understand the structure of the object and the shapes to use to recreate the shape needed.

Exercise 2: Cylindrical Modeling
For this exercise, we were required to use the tools we've learnt on week 3 to create a few cylindrical models with the use of a cylinder as a starter shape. We learnt on the basic of using tools in the editing tab which allows us to do so much such as extruding, inset, scaling, beveling and so on. My skills after this exercise was so much better than before though it was confusing to figure out the coloring part. I was quite satisfied with the outcome of the composition tho.

Exercise 3: Box Modeling
For this exercise, we need to build a model using only 1 dominant cube for the main body of the object that is made of box shape. My idea was to make a bed with the reference I found online as it seems like it's quite easy to remake with the blueprint I found. Most of the shapes I created was through bevelling a box shape which was a smooth process. The only issue I stumble upon was when I was trying to make the pillow to look more curvy rather than a square block. This exercise allows me to familiarise myself with the tools on blender while learning how to edit a shape. I'm quite satisfied with the outcome.

Exercise 4: Organic Modeling
The fourth one is just a submission of a karambit we did for tutorial. I was quite easy to follow through the tutorial in class as Mr Kamal took time to show step by step on how to do it. The tip of the knife was the trickiest as I kept failing until Mr Kamal saved me from my misery. I think everything looks great to me except for the lines formed on the top of my blade that I was failing to fix.
