Image Synthesis Program 8


CPSC 6650 Program 8

Add explcit direct lighting to your Cornell box.

Extra Credit

Make a cornell box with slightly rough surfaces using lots of triangles and small random position adjustments.
  • All images have gamma correction 1.6
    The best thing to experience about this program is its reduction in the time it takes to complete an image. I will give some images and list the time it took to render them and the number of samples. The images are all at a max depth of 4. Columns 1-3 apply to explicit direct (this assignment). Columns 4-6 apply to implicit direct (last assignment).
    Number of SamplesTime Image w/ Correct Light Image w/ White Light (if present)
    4 22s
    161m26s
    645m 43s
    400 34m 58s
    1600 2h 19m 47s
    10,000 14h 51m 9s
    I'd also like to show the difference between a point light source and a square light source at 400 samples depth 4.
    Point Light (15m43s) Square Light (15m37s)
    It'd also be nice to compare the explicit and implicit direct lighting with one another. I'll compare my best sampled direct lighting with the closest explicit direct lighting image that I could find.
    Explicit (225 samples ~20m) Implicit (10000 samples ~15h)
