Hi,
I wasn’t sure if this is a VFX or Tech art thing. I’m looking at the Nvidia GPU Gems book https://developer.nvidia.com/gpugems/GPUGems/gpugems_ch01.html and I’m trying to create normal maps for the Gerstner waves. I’m strugglling with one thing. I dont know what the P is for the C() and the S() equations.
Here is the Normal map equation:
Here is the actual material setup without the P: https://blueprintue.com/blueprint/7o0vzok0/
I wasn’t sure if Its important to have it in or not and I wanted to confirm with you guys if this is ok? My math isn’t as good as it used to be and I’m looking into doing a refresher course soon but in the meantime I could use some help.
