Pyro Infection

Volume-based infection spread simulation — pyro solver driving a growth front that consumes surrounding geometry frame by frame.

Houdini learning experience using Pyro Solver, MaterialX, and Karma. The pyro solver selects particles which spread the infection across the lion’s surface; MaterialX handles diffuse, metallic, and emission shading variants; final renders go through Karma in Solaris.

Techniques

  • Pyro Solver — selects and spreads infection particles
  • MaterialX — diffuse / metallic / emission material variants
  • Karma in Solaris — final rendering
