Reaction Diffusion and Land Erosion (vuonode + example composition)

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.

Ashima Noise Filter (vuonode + example)

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.

This is an example that uses the Vuo audio wave to influence a simple water simulation.

This is an example of a plugin that can create an emboss effect, aka "normal map" aka "bump map", from an image's input luminosity.

Included are the compiled vuonode plugin, an example composition, and the Qt project.
