Unit 1: Transformations
Weeks 1,2. Ass 1 due Sep 25
Unit 2: Spline Curves
Weeks 3,4. Ass 2 due Oct 7
Unit 3: OpenGL
Weeks 5-7.
Ass 3 due Nov 11
Midterm on units 1-3: Oct 20
Demo: Surreal (HW 3)
Methodology for Lecture
This unit different from others in course
Other units stress mathematical understanding
This stresses implementation details and programming
I am going to show (maybe write) actual code
Same code (with comments) available online to help you understand how to implement basic concepts
I hope the online code helps you understand HW 3 better
ASK QUESTIONS if confused!!
Simple demo 4160-opengl\opengl1\opengl1-orig.exe
This lecture deals with very basic OpenGL setup. Next 2 lectures will likely be more interesting
Outline
Basic idea about OpenGL
Basic setup and buffers
Matrix modes
Window system interaction and callbacks
