Simulation with the Flow Solver over 3D Surface

Simulation with the Reaction Diffusion Solver over 3D Surface

Editing 3D Surface using animated COPs layer

Using COPs simulation to drive animated growth in SOPs

Use procedural animated SOPs attribute in 2D simulation

Wood Worm

This project mixes Houdini’s new Flow Solver with the Reaction Diffusion COP to create evolving patterns that live on 3D geometry. The technique adapts Yancy Lindquist’s UV-Island workflow, but pushes it with Copernicus’ GPU solvers.

SOP attributes drive sources inside COPs, the layers feed back into SOPs for procedural modeling, and the whole loop ends in a ready-to-render Solaris scene.

This project requires a SideFX Labs installation.

"The node worm_wood > reaction_diffusion > get_Flow_solver_data is reporting the following error: Unable to read file 'C:/Users/Administrator/Downloads/wood_worm/flow/flow_surface/v1/flow_surface.0001.exr': Is this because a texture is missing?"
