Lava Lamp Shader

A procedural lava lamp effect based on raymarching signed distance fields

• Multiple zones where different lava colors can be specified on a single mesh

• Lava correctly moves with the animations of rigged characters

• Object thickness is correctly calculated for all viewing angles using a signed distance field texture representation of the mesh, which is precomputed using a custom mesh to SDF compute shader

• Depth based intersection between lava and objects inside the lamp

• Physically based refraction through the glass shell
