Today's agenda

1. Read up on textures in CUDA, and implement to see how much faster the diffraction kernel becomes.

2. Try to get the shader version working. Some bugs in the code right now cause the output to be a black screen. The processing is happening though... because the computer hangs for around 5 seconds while the shader executes...

For this, I will be using the "Adaptive tessellation for displacement mapping" source that I wrote with Rohit as the code base.

3. Purcell's PhD thesis is still elusive :)
