Announcements

Project 2 final drafts are due by midnight Tuesday (5/7) on Blackboard.
The final exam will be in-class this Tuesday (5/7) at 10:15am in our usual classroom, Chapman 201A.
Project 2 presentations are this Thursday (5/02) in class!
Project 2 rough drafts are due Thursday (4/25) on Blackboard by midnight.
Grades for your midterms and Project 1 are (finally!) posted on NetRun.
Project 1 final drafts are due Thursday, March 21 at midnight on Blackboard.
Project 1 presentations were in-class Tuesday, March 5th.
The take-home midterm is on Blackboard, and due back by midnight Thursday, 2013-03-07.
Project 1 rough drafts are due on Blackboard by midnight Thursday, February 28. This should (1) work, and (2) be a solid step toward where you want to end up, but doesn't have to be polished or have all the features you eventually want.
Homework 2 is posted, and due Thursday, February 21 by midnight on Blackboard.
Project 1 details are posted. Topics are due in class Tuesday, February 12.
Homework 1 is posted, and due Thursday, February 7 at midnight.
Homework 0 is posted, and due Thursday, January 24 at midnight on Blackboard.

Resources

The course syllabus has dates to remember, and the grading policy.
Illuminating WebGL examples:
- Interactive reflective ball via a mass/spring system and Three.js.
- Mass-spring system with constraints and excellent descriptions of the underlying rationale.
- cannon.js: Sphere and cube collisions library, via a spring-and-damp penalty method.
- Cloth simulation . Renders the cloth positions and velocities into floating point textures.
- Water ripples, refraction, and caustics. Uses a bunch of shaders doing different things to a single 2D texture of water heights.
- 2D fluid dynamics via Stam's stable fluid version of Navier-Stokes. Written in bare WebGL, so it's long but clear (see his other neat examples).
- Texture synthesis and depth of field blurring.
- Landscapes, lakes, and soil. Interactive erosion!
