Blending OpenGL with video
Oct 16 2010 | 11:13 am
I've been trying to create something which mixes several layers of video with an OpenGL render. I think my problem lies in creating an alphamask for the render with the video grab: it appears to be dropping the resolution of the GL shapes down to that of my jit.qt.grab, rather than just masking the output.
I'm sure I'm just approaching this the wrong way, so whilst I'm happy to post my crazy, sprawling patch if need be, I thought it might be just as easy to see if anyone can point me in the direction of a reference/tutorial/post that covers this? I get the feeling I can't see for looking!
