Project

The project is focused on practicing techniques of modelling and rendering learned on exercises. It is split into two stages evaluated separately throughout the semester.

Note: Accomplishing bonus tasks grant you an additional points, but cannot get you over the maximum of 100p from exercises.

Stage 1

Blobby: candle, toy (teddy bear, dino, ...), etc.


Evaluation
Use correct modelling techniques for each model category (15p)
