Program: CS 484 Assignment 3: GLSL Shader Author: Kyle Maysey Email: Kyle_Maysey@csu.fullerton.edu Description: This program uses the open GL Shanding Language to implement phong illumination. Currently the program is loading a sphere generated by glut to allow me to better visualize how my shaders are operating. Controls: Space - Toggle light movement mode or model movement mode when mouse left click is held down. Left Click - In conjunction with moving the mouse it will translate the light source, or the object. Modifiers: - Control: If control is held down it will restrict translation to z axis. - Shift: If shift is held down it will restrict translation to the x and z axis. G - Toggles the use of the shaders and the fixed openGL funcionality. Esc - Quit application How to run: 1) In the command prompt, make the folder containing "glslshader.exe" your working directory 2) Now call "glslshader.exe -x [vertex shader ending in .vs] -f [fragment shader ending in .fs]" to run the project. Example command line: glslshader.exe -x shaders/phong.vs -f shaders/phong.fs Known Bugs: -- When light is close to the edge of the sphere it appears to generate a second light around the edge. Was more pronounced when I was using the half vector between the eye vector and the light vector, as opposed to calculating the reflection vector.
