Free TouchDesigner Component: WaveTOP Wave Equation Water Simulation in TOPs (Tim Gerritsen)

Overview

Tim Gerritsen (y=f(x) lab) shares WaveTOP in the Derivative community Asset section, an implementation of the wave equation using only TOPs with no custom GLSL. It creates a heightmap that can displace a Grid SOP into a water-like surface.

The red channel of the first input adds or subtracts volume in the field, while pixels above 0 in the second input are masked out so the waves bounce off the border. The post explains how the Laplacian is computed from neighbouring pixel differences in the /WaveTOP/Laplacian component, and WaveTOP.1.0.tox (27.26 KB) is a free direct download.
