  • New paint tools: pencil, brush, color picker. Paint on images and meshes, even while the system is running.
  • Undo/redo mechanism for paint actions.
  • Bug fix: Color bar colors were garbled on some platforms.
  • Bug fix: Some lines in the 1D view appeared black on some graphics drivers.
  • Bug fix: Conflicting preferences file from previous versions would cause blank window. As an interim fix in 0.3, use View > Restore Default Layout.

New in Ready 0.3 (Jun 25, 2012)

  • Reaction-diffusion can now be run on the surface of meshes, or in a volume of tetrahedral cells. Load the *.vtu files to see examples.
  • New menu commands:
  • File > Reload from Disk : reloads the current pattern file from the saved version on disk.
  • File > Import Mesh : imports mesh files (*.obj, *.vtp, *.vtu) as surfaces to run RD on.
