Email me at xinranliuart[at]gmail.com with your questions and attach a jpg if applicable. I'll try to answer within 48hrs!
Assignment for next week:
Finish the form rendering exercise started in class. Render an organic 'blob' following a given direct light source of your choice, referencing a rendered sphere for the values. Use the half-way to black method to assign believable values.

Additionally, add the following modifications/manipulations to your rendered form (refer to the smaller blob on the left, above):
- Add an attachment/protrusion
- Have both smooth and flat surfaces (aka smooth vs fast value transitions, aka soft vs hard edges)
- Flatten a part of the form or slice something off to create a flat plane somewhere
- Punch a hole somewhere
- Add a deep cut / trench / indent
- Add a dimple
- Add occlusion shadows where appropriate
- Fake a quick cast shadow on the ground plane
Reading for next week:
I highly recommend that you read through Scott Robertson's take on the theories and principles we discussed in class. I promise it won't take long! There are a lot of pictures and diagrams :)
How to Render:
p. 18-19: Value change = form change
p. 20-21: Direct vs. Soft light
p. 22, 60-61: Light decay (falloff)
p. 23, 67: Occlusion
p. 26, 58-59, 67: Reflected Light (bounce light)
p. 52-53: Light set-up and 1-2-3 read
p. 54-56: Half-way to black and ambient light
p. 65, 79: Shadow terminator and combine shapes
p. 66: Specular (refletive) highlight
p. 86-87: Cast shadow edges
