Pseudorandom Surfaces 06: Surface Flow
The final part of the pseudorandom surfaces series adds particles that flow across the surfaces of planes and spheres, flowing either downhill or along elevation contour lines. Surface Flow (Catlikecoding)

Pseudorandom Surfaces 05: Spherical Elevation
We're not limited to applying noise to planes. Now we can also displace the surfaces of spheres. Spherical Elevation (Catlikecoding)

Pseudorandom Surfaces 04: Voronoi Derivatives
We also calculate the analytical derivatives for Voronoi noise. As this noise has sharp ridges and points we also introduce a smooth variants of F1 Worley noise. Voronoi Derivatives (Catlikecoding)

Pseudorandom Surfaces 03: Perlin Derivatives
After taking care of Simplex noise we also calculate the analytical derivates of value and Perlin noise. Perlin Derivatives (Catlikecoding)

Pseudorandom Surfaces 02: Simplex Derivatives
In this tutorial we introduce analytical derivatives and use those to construct normal and tangent vectors. Simplex noise is simplest, so we start with that. We also include a smoothed version of turbulence. Simplex Derivatives (Catlikecoding)

Pseudorandom Surfaces 01: Surface Elevation
Now that we have both pseudorandom noise and procedural meshes, we combine the two and create pseudorandom surfaces! Surface Elevation (Catlikecoding)
