PLY to STL Conversion: FAQ

What are PLY files?

PLY or "Polygon File Format" is an extension used for storing data collected with 3D scanners. It is also known as "Stanford Triangle Format" because it was created at Stanford University in the mid-1990s, with a design inspired by Wavefront's OBJ vector format. A PLY file contains a 3D description of an object through a list of nominally flat polygons, as well as info regarding color, transparency, textures etc.

What are STL files?
