This is a vuonode that generates a circle pattern, meant to be somewhat similar to Vuo's checkerboard generator in purpose and design.
Features a "noise diffusion" - basically, a feedback effect that's been perturbed by noise.
This is a somewhat novel Reaction Diffusion simulation in that sequences of events can cause the appearance of land eroding, or a surface boiling.
After triggering spiral effect, areas of brighter intensity can form, which successive settings will appear to erode or boil away.
This is an implementation of Ashima noise that repurposes it to be an image filter.
You can also use the "viewPositions" option to use it to generate noise positions sans rendering of input texture.
This is a height field shader that interfaces with Vuo scene objects.
The height field extrusion can be adjusted in any direction - x/y/z.
The width, standoffWidth, and showThirdEdge are for wireframe effects. A width of 1 should create the effect of a solid mesh.
