This project includes some examples of Reaction Diffusion (RD) simulation with SNLite node in Blender Sverchok add-on.

This project includes:

• Python script that simulates 2D RD with C code.
• Python script that simulates 3D RD with C code.
• Python script that simulates 3D RD "without" C code.
• Python script that simulates RD on mesh with C code.
• Python script that simulates RD on mesh "without" C code.

Python scripts "with C code" uses these C codes as C dynamic libraries. So you have to compile these C codes to generate C dynamic libraries in advance. Though you have to do so, these scripts runs very fast and achieves high performance.

Scripts "without C code" can run without C library. But the processing speed and performance are relatively low.

This project idea is originated from @zeffi's gist and nortikin/sverchok#1734 .

• Compile C code and make C dynamic library.

  :: Windows
  cl.exe /D_USRDLL /D_WINDLL Basic_RD_xd.c /MT /link /DLL /OUT:libBasic_RD_xd.dll

  # macOS
  gcc -dynamiclib -o ./libBasic_RD_xd.dylib ./Basic_RD_xd.c

  # Linux
  gcc -c -fPIC Basic_RD_xd.c -o Basic_RD_xd.o
  gcc Basic_RD_xd.o -shared -o libBasic_RD_xd.so

• Launch Blender and open Sverchok node editor.

• Add Script Node Lite (SNLite) node.

• Open Text editor in Blender.

• Copy and paste one of the Python script to the text buffer.

• Modify "load_library" arguments in the script to load your library (if you use "with C code" script).

• Put the the text buffer name to the node and click the right button.

• Blender 2.8 (or later)
• sverchok add-on 0.6 (or later)
