Rendering with positional encoding

Question 4.1

To improve the model I added view dependence by appending the viewing directions to the output of the spatial MLP. I then passed this to the feature MLP in order to generate the colors.

Question 4.3

High resolution rendering, 40 sample points, 250 epochs

Unfortunately the most amount of points I could sample was around 40 before I ran into CUDA memory issues. Because of this low sampling frequency, the renderings were a bit blurry. However, by halfing my chunk size parameter to 16384, I was able to sample closer to 80 points in order to get less blurry images.
