WEEK 1

Briefing:

Mr. Kamal briefed us on all our projects and basics on how to use and navigate blender

Notes:

ctrl(hold) + alt(hold) + Q toggle to quad view

T = hide tool bar

N = hide side bar

Shift C = return cursor to world origin and frame all selected

Y axis = Green

X axis = Red

Z axis = Blue

G = Grab

RMB to cancel

LMB to comfirm

S = Scale

R = Rotate

Alt G = return object to origin

Shift A = Add object

CTRL P = Parent

Practice

He then demonstrated and asked us to follow along to make something simple. We also learned how to apply material.

EXERCISE 1

Briefing:

Fig 2.1. Exercise 1 brief

Sketch:

I decided to make a pocket watch so i sketched out the idea first.

Fig 2.2. Sketch

Blender:

I started with a cylinder flatten down and used a torus to create the outer ring. By reducing the segments i was able to make it look like a sharp edge.

Fig 2.3. Progress 1

To make the clock hands, I made the second hand then parent the object to the center cylinder. Then I duplicated 2 more to edit the hour and minute hand.

Fig 2.4. Progress 2

I added a torus in the middle to make sure the hour lines are in the right positions. I used 30 degree angles to angle the lines

Fig 2.5. Progress 3

To make the handle I used a torus. Then for the hinges i used multiple cylinders. I duplicated the body of the watch to make the back of it. I also added some designs at the back for fun.

Fig 2.7. Progress 5

After Parenting the bottom to the top of the watch, I posed it and created planes. I added lighting and composited it.

FINAL OUTCOME:

BONUS:

I wanted to show the back too.

WEEK 3

Practice:

We learned in class how to make a bottle from a reference image. We learnt about edit mode.

Fig 3.1. Cylindrical Model Practice

Notes:

Bevel - Edges, Bevel (Ctrl + B)Apply in Edge*
can just grab a face and move to extend an object
Extrude Faces- Face, Extrude Faces (E) Apply it in Face*
Extrude can be applied on any surface.
Face, Extrude Along Normals (can extrude outwards)
Don't extrude multiple times. Will overlap.
Alt + Left Click will select all horizontal sutff.
Use Loop Cut to cut an object into multiple parts. (Ctrl + R)

Offset Edge Slide (Shift + Ctrl + R) Create more edges?? from edges??
Modify, Subdivision surfaces increases the subdivison
(?) can isolate object
(I) to add subdivison
(F) to close a hole

EXERCISE 2

Briefing:

Fig 3.4. Exercise 2 brief

Process:

Fig 3.5. Ref 1

Fig 3.6. Ref 2

Fig 3.7. Ref 3

Fig 3.8. Ref 4

First, I looked for references. after finding them I opened a new file to start making them. I followed the process we did during class.

WEEK 4

Slides:

Fig 4.1. W4 Slides

Practice:

We learn to make a low poly car in class
Can use knife tool or vertex connect path (j) to connect 2 points.
You can extrude inwards
Shift s to put the cursor to world origin
after duplicate, press right click to cancel selection.
Set object to cursor at world origin before mirroring object.

EXERCISE 3

Briefing:

Fig 4.3. EX3 brief

Since we were already mostly done with the car during class. I decided to refine and add more things based on the reference. I had trouble with making the car mirror, but I learnt to use the rotate function more. That helped a lot with creating the steering wheel and mirror.
