Hi All Have a quick question about render to texture. I'm trying to use it in an AR app on IPhone so I can do some post processing on my final scene etc. At the moment only FRAME_BUFFER mode works and is quite slow. I know OpenGLES supports FRAME_BUFFER_OBJECTS I know these to be a little faster so I'll probably try getting these working.
My question is, are FRAME_BUFFER_OBJECTs the fastest or should I look into PIXEL_BUFFER_OBJECTs? (If there even supported) Or I guess has anyone already done the work for FBOs on IPhone? Tom PS I know I could look through the code but does FRAME_BUFFER mode use glCopyPixels, just curious?
