Game Graphics Assignment 12

I hadn't done the directional lighting before this assignment, so that was the first thing I had to do. With that I wanted to use functions for my shaders. Although I did not do this for every part of my shaders, specifically the vertex shaders, I did convert my fragment shaders to use functions.

This caused some problems with lighting, but eventually I was able to refactor my lighting to such a way that I could use modular functions to do the lighting. The one problem that I found after doing this was that if I made a change to one of the function files, it would not recompile the shader. So when I was playing with the epsilon of my shadows function I would have to go into a shader and add/remove a space, save and then run the game. So if I were to do this again (presumably for something more than class) I would find a way to get a dependency graph working for the shaders.

There were plenty of minor mistakes I made with the code, but overall I had no major problem with the assignment.

One thing that helped with the assignment was the GUI. I changed my GUI item to show the shadowmap texture which allowed me to see the lights perspective at all times. This wasn't a life saver, but it was really easy to do and it was helpful.

Here is a screeshot of pix for the shadow map texture.

Everything should be working.
