I've now extended ReDiLab: Node to include to support a handful of new reaction diffusion models:
- Belousov-Zhabotinsky: the famous chemical reaction that displays characteristic spiral wavefronts (this runs really quickly, so you may want to change the iterations value to slow it down).
- FitzHugh-Nagumo: the relaxation oscillator that frequently exhibits tip splitting and models spike generation in squid axons.
- Willamowski-Rössler: another model of chaotic chemical reactions with a hefty ten parameters.
The latter two models use the same nine point Laplacian stencil I've used for the original Gray Scott model.
The output of any of the four models can serve as an input to any other. In this current implementation, only the blue component can be used as an output, but this will change in the next version (along with the introduction of even more models!). Stop press! The latest version of ReDiLab: Node now supports red, green and blue outputs!
Having a selection of models massively increases the variety of networks that can be created:
I've added a selection of new scenes which are available under the 'presets' popup.
The new application is available here and the source code, as always, is available here.
