Oct 2nd, 2008, 7:52pm   Hi, Does anyone know of a way I can achieve something similar to Processing's modelX/Y/Z whist using OpenGL's glTranslatef / glRotatef to do transformations ? I'm kind of assuming not, but it's hard to google things you don't know the name of... Many thanks, B

Reply #2 - Oct 3rd, 2008, 1:05pm   Thank you, though gluProject seems to convert world to screen, and I'm looking to convert local ( after transformation ) world co-ordinates to global world co-ordinates. I'll keep looking, thanks again.

Reply #3 - Oct 3rd, 2008, 1:10pm   ah, I didn't know what modelX did, I was remembering screenX. modelX sounds really useful, if you do find out how to do it keep us posted. Could it not be simply multiplying the coordinates with the inverse of the modelview matrix?
