Assignment 2
CS155 - Graphics
For assignment 2 in cs155 we were asked to implement a ray-tracer. Here's a list of the current features of my ray-tracer:

Shapes:
• Sphere primitive
• Triangle primitives
• Cylinder primitives

Other Fancy Features
• hierarchal Coordinates. Ok. So this one isn't that fancy.
• Texture mapping with bilinear filtering
• Full lighting effects.
  • Point lights
  • Directional lights
  • Spotlights
  • Color Projection
  • Shadows
• Refraction. accurately predicts Snell's law.
• Reflections
• Jittering: Super sampling, fuzzy reflections and fuzzy refraction.
  This increases processing time a significant amount, but it does make smoother images. Probably not worth the extra time. Since a jitter value of 10 looks best but takes a very long time... Very long, so very long.
  Instead of just averaging the randomly jittered rays, I took a weighted average of the rays based on how different from the original ray. I felt this would allow the image to become smoother while still keeping the sharpness.
  For instance, this image was produced with no jittering:
  While this was produced with 3 jitter rays for supersampling, fuzzy reflections and refractions:
