Project 6: Terrain Shaders
In this project you will need to render a terrain with a GLSL shader program.
This project is due on Friday, May 15th, 2015 at 1:00pm. You need to present your results in the CSE basement labs as usual, grading starts at 12:15pm. Please upload your source code including your shaders to the Ted system by 1pm. You do not need to upload any binaries, including textures, 3D models, etc.
The discussion for this project will be on Monday, May 11th.
The total score for this project is 100 points, plus 10 for extra credit.
