What is it?
.cc3d files are the simulation project files for use with CompuCell3D. They essentially are an XML file that is stored in a directory with the other simulation files. .cc3d files were introduced in to CompuCell3D version 3.6.0.
An Example:
Below is a simple example of a .cc3d file. It defines all the files need for the simulation. In this case the simulation files reside in the directory Simulation which resides in the same directory as the .cc3d file.
<Simulation version="3.6.0">
<XMLScript>Simulation/Cellsort.xml</XMLScript>
<PythonScript>Simulation/Cellsort.py</PythonScript>
<Resource Type="Python">Simulation/CellsortSteppables.py</Resource>
<PIFFile>Simulation/Cellsort.piff</PIFFile>
<Resource Type="Field" Copy="No">Simulation/FGF.txt</Resource>
</Simulation>

How do I open it?
These files are intended to be used with CompuCell3D. This tool can be found here on nanoHUB
