Category Archives: File Conversions

Doing a little research on file conversions…

Quick google search revealed this page which has a fairly recently updated list of 3d model file format conversion tools, with annotations.

What looked to me to be the most promising tool is MESHLAB…

What interested me most was the ability to both import and export models in numerous formats, including PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF, GTS, plus several others. I tested the conversion fidelity with DAE and 3DS and found them satisfactory.

MESHLAB is open source [free for you]. I’ll test as time allows… or you guys can try it out and report back to the class.
