Description: General discussion of reaction-diffusion systems such as Gray-Scott, and more specifically about the open source implementation here: http://code.google.com/p/reaction-diffus ion/
 

extend the smoothlife_smoothglider.vti 
  ... You're right, Full Kernel patterns are not the same in a grid simulation vs. a mesh simulation. The problem with SmoothLife (from Ready's point of view) is that it is not a reaction-diffusion system. Nearby pixels influence each other in a way that cannot be approximated by the normal Laplacian function.... more »

extend the smoothlife_smoothglider.vti 
  Is it possible to apply "smoothlife_smoothglider.vti" pattern to another mesh other than the default built-in plane? What I usually do with other patterns is to copy the formula and parameters and paste them into my new mesh (a sphere for ex.). I haven't had any luck with this extremely interesting pattern, maybe because is in Full Kernel Form. By the way I... more »

Kernel code documentation 
  Hey, Another post. :) Struggling to find some kick starting documentation around writing OpenCL kernel code for Ready. I understand that kernel coding is agnostic to Ready. But I can't seem to find the option to create a new kernel pattern, as opposed to a formula pattern.

Ready as a lib 
  I thought I'd have a go at compiling the readybase project into a lib or dll to use in other projects, however its quite the task trying to unravel it into a single lib or dll given all the VTK integration it appears to have. Anyone managed to successfully do this?

Simulating Volatile Gases and Fire 
  Hi, Ready is amazing! I'm currently integrating the lib into a real-time environment and simulating basic gas diffusion and temperature (Same rules, different lattices). I'd like to simulate in real-time some basic interactions with the gases I'm using (Purely arbitrary). Example is a fire starts at some x,y location in the gas lattice and what should happen is... more »

Suggestion 
  Ready has a really nice "About" command that displays a little window containing, among other things, the name and version of the program, copyright dates, names of the programmers, licensing information and a link to the source repository. I suggest that this information should also include:... more »

Instructions in case attachment didn't come through (was Re: Preparing for a 0.5 release...) 
  I didn't say so, but that message had an attachment "ising-test.vti". In case you don't get it, here are instructions to create your own: * In your Ready patterns list, hold down the Control key while selecting "Ising_regime.vti". * This will open "Ising_regime.vti" into TextEdit. * In TextEdit, do a "Save As..." and put the copy on your desktop (or... more »

Initial condition and Boundary Condition 
  Dear Friends, I am working on pattern formation in reaction diffusion system(for example FitzHughNagumo Equation). I am using Finite difference approximation to simulate it. I want to know what kind of initial condition (random uniform or random normal) is realistic ? Also I... more »

Gray-Scott model 
  Good. This was a great discussion. I'll try to take some of these ideas about stability and add them to my web page describing how to compute Gray-Scott. I'll also make suggestions on the reaction-diffusion mailing list, where the Ready program is discussed. I'm not sure if you're on it, but the reaction-diffusion mailing list... more »
