See attached files.
The Lab 3 deadline has been extended to Wednesday, Dec. 5th, midnight. Lab 4 is attached; it is also due on Wednesday Dec. 5 at midnight. You will submit both assignments together (you can just submit one set of files, as lab 4 must contain all lab 3 code; just be sure that your lab 4 documentation includes all lab 3 documentation).
There is a tutorial today. I might be a bit late due to a dentist appointment. Hopefully not though.
The starter files DO NOT contain provided answer code for Lab 3, nor will you receive any answer for code for Lab 3.
Super big hint: go take a look at one of the early slides on the course website. On one of the last slides, it includes some MiniGLSL and the corresponding ARB fragment assembly.
