Ready       Build Status

Ready is a program for exploring continuous and discrete cellular automata, including reaction-diffusion systems, on grids and arbitrary meshes. 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 data, as well as polygonal and polyhedral meshes.
