Build Status

Ready

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.

Download Ready 0.7 here:

We're working on the next version, which includes two new features:

  • Import of images, so you can use a photo as the initial conditions of a pattern
  • Export of a sequence of OBJ files, for animating a 3D mesh.

For now these features are only in the 0.7.2 release or later.

More details on the releases tab.
