Toon cloud
Cloud with different render algorithm: Mesh, POM, Volume
Mesh cloud
Render a cloud with a mesh, and use a shader to simulate the cloud's movement and shape change.
POM cloud
Use the Parallax Occlusion Mapping to sample noise texture.Volume cloud
Use the Ray Marching(GDC) to sample multiple FBM noise(Perlin/Worley) texture.TODO: FBM parameter still need to be adjusted, and the performance is not good.
