Ready

Ready is a program for exploring continuous cellular automata, including reaction-diffusion systems. OpenCL is used as the computation engine, to take advantage of the many-core architectures on graphics cards and modern CPUs. OpenCL also allows rules to be written in a text format and compiled on the fly. Ready supports a compact XML-based file format so that images and rules can be shared easily.

Ready supports 1D, 2D and 3D patterns.

Download Ready 0.2.2 from the links on the left, or the Downloads tab. Ready works on Windows (XP+), Mac OS (10.6+) and Linux.

Older research code:

In the source folders you will find early versions of code we were using to explore RD systems. Eventually all of this will move into Ready.

Currently implemented:

• Turing spots,
• Gierer-Meinhardt spots and stripes,
• Gray-Scott,
• FitzHugh-Nagumo
• FitzHugh-Nagumo in 3D
• complex Ginzberg-Landau
• Brusselator,
• Oregonator (help needed!)
• Brandeisator (help needed!)
• Schlogl
• Schnakenberg (help needed!)
• Edblom-Orban-Epstein
• Linear model (help needed!)

Features:

• Cross-platform,
• Graphical output using OpenCV,
• Can save images/videos,
• Simple implementation for teaching purposes
• Example implementations using OpenMP and OpenCL.

Other packages:

• TexRD (closed source)
• Visions of Chaos (closed source)

Wanted:

• K. Maginu, "Reaction-diffusion equation describing morphogenesis I. waveform stability of stationary wave solutions in a one dimensional model", Math. Biosci. 27:1/2 (1975), 17–98 http://dx.doi.org/10.1016/0025-5564(75)90026-7
• L.Decker 2003, derived from Maginu's (from TexRD)
• L.Decker 2002, derived from Ginzburg-Landau (from TexRD)
