Shading Features

• Flat shading
• Gouraud shading
• Phong shading
• Ray tracing

Notes

• Objects to be ray traced must be placed on a 2x2 grid from (-1, -1) to (1, 1) instead of the 500x500 grid. This is due to how the pinhole camera model works. I couldn't get it to work on the 500x500 grid.
• Ray traced polygons become invisible or glitch out sometimes.
• I spent so much time debugging my ray tracing code that I had to abandon my original plan to create antialiasing and upscaling algorithms.
