hmmm... interesting. perhaps I should explain a little more of what I'm trying to achieve.
http://www.zebraimaging.com/ these guys seem to do some pretty interesting 3D holographic prints which can take in obj format model etc however to get shading and geometry shaders etc out of the scenes set up from rendering strikes me as a bit cumbersome. ( it can take baked textured etc) They also take in .pts (pointcloud files) or .xyz text files (not sure what they do for colour though) Looking at the positiontopoints stuff in nuke I figured that I could perhaps just render whole scenes with a points pass and find someway to convert the data in the .exrs to a combined pointcloud. I don't think an obj is going to give me what I want . Looking inside the file in a text editor seems to have a whole bunch of points which I could reformat as needed but no colour information. Thanks for the assistance.

I'm looking for a way to export the 3D point position data that I can collate using the positiontopoints setup in Nuke as either .xyz formatted text or as a .pts file etc. Basically I want to be able to generate pointcloud data for other apps from my renders. Anyone got any insights?
