You tease... Well, for vapour it's looking promising - especially from the short list of features you've offered. OpenGL, Win/Mac/Linux and the "different 3d formats". If you don't mind answering at least a couple of questions. Hey, you knew when you posted this you'd get blasted from people around here with a barrage of questions, begs, wishes and general "wow cool" remarks. :) "be able to read several 3d formats" is a bit ambiguous. Poser can "read" several formats, but it can't work with them properly. Being able to load something is vastly different to recognising the format and using it properly. Poser can import 3ds but mangles the uv co-ords, hierarchy, parenting and most other things contained in the file. Will your app improve on that and utilise the various formats properly or just be another "it's a thing, here it is" utility that only utilises object? That's slightly more important than might at first appear and not just because of the obvious savings in space. :) I don't expect you to give a technical answer but some sort of explanation of that would be kinda nice. :)
