CellBlender is an addon for Blender-2.6x to create computational cell biology models for use in MCell and potentially other cell simulation biophysics engines. In CellBlender 0.49 you can create geometric objects, assign surface regions to said objects, export the objects as MCell MDL geometry files, set MCell simulation parameters, import a time-series of MCell VIZ_OUTPUT, and interactively playback or render an animation of the VIZ_OUTPUT. MDL import along with other features will be added in future versions.
CellBlender is replacing PSC_DX and DReAMM as the primary tool to visualize MCell simulations.
