HW1: Shiny Red Triangle
CS 481/681 2007 Homework, Dr. Lawlor
Your first homework is to write an OpenGL graphics application with:
If you can't do these things after looking at the CS381 examples, this class is going to be very hard for you!
- One red triangle.
- Some way to interactively rotate the triangle through a
substantial angle (using the keyboard, mouse, a GLUI_Rotation, another
GUI slider, etc.)
- Some sort of reasonable lighting--and specular per-pixel lighting looks especially nice! Don't worry about shadows.
- Some use of programmable shaders, like GLSL.
Here's a screenshot of what I wrote. I started with the
"tiny_glsl.cpp" example, added "#include <glew.c>" to fix the
link error, added GLSL compile error checking code, wrote a pixel
shader, added a rotation matrix, and hooked it to the mouse with
glutMotionFunc. I think I'd have had a much easier time using my
ogl libraries, though...
