The plugin includes:
- Set of shaders that perform frequency Specturm, IFFT(inverse fast fourier transform) and Normal in Compute Shader and Pixel Shaders.
- Tessellation Enabled
Todos:
- maybe combine Quadtree with FFT for infinite Render
- normal needs to be in tangent space.
- add bouyancy physics
- add interactive height field wave simulation with render texture and compute shader
Part of this project code is also been used alongside with newest most popular ocean plugin in UE marketplace
Oceanology update. If you want something that's more commerical:
