Converting *.c3d into *.stl using Matlab

Dear All,

I'm looking for someone familiar with MatLab code to convert point data (or positional data) into a volumetric file. The point data is in *.c3d that and can be further exported as *TRC (track row column). The final output should be a volumetric file in *.STL.

Ideally this converter can be a stand-alone or a plug-in for DS SolidWorks 3D Modeller.

Cheers, Eujin
