PTEX support

[WickedAndy]

be nice not to have to deal with UV's... especially since it's almost impossible to re-do uv maps on any super high res geometry...

I just thought I would bump this with a gigantic +1

I'm so over faffing about with gigantic unusable UV maps. That is a general complaint not specific to PhotoScan :-)

one doubt though... does Ptex supports tris...? I thought quads only... at least in 3DCoat..

Yep (http://ptex.us/tritex.html), although not all applications implement the full ptex spec.

Mari is one painting app that I know for sure supports ptex triangles.

Nvidia has released couple of papers on how to render ptex on gpus.

might be useful.

mmmm still wondering about the tris, because both the papers Jarkkol posted are saying Quads ONLY..

Here is an answer to the question of using Ptex on dense triangle meshes, straight from the mouse's mouth as it where.
