CUDA Navier-Stokes Solver

sloxton — Sun, 31 Oct 2010 09:36:01 +0000

This is the first working version of a CUDA Navier Stokes Solver I have written as a Houdini plugin.
It uses Semi-Lagrangian advection and a Jacobi iterator for pressure projection.

The current steps are:

Apply force
Velocity self-advection
Diffusion
Project Non-divergence
Compute no-slip boundary conditions
Temperature advection

Ocean Storm

sloxton — Tue, 02 Sep 2008 11:40:42 +0000

This is my first personal project using Houdini.

It uses the Houdini Ocean Toolkit to deform the ocean geometry using algorithms developed by Jerry Tessendorf. The twister and spray was all controlled using custom OTL’s inside Houdini.

Custom shaders produced the following extra output passes that were then comped together:

Ocean – Diffuse, environment, specular and fresnel
Twister – Several layers of particles rendered as sprites with an additional layer of mist
Spray – Foam and spray emitted from the eigenvalues in a shader
