I've spent some time digging and I'm not pulling what I need. Is there a general way in opengl to have multiple views of shared rendering data? What I mean is something like this. In window A, I have 3 Textures being rendered. In window B, I'm rendering only two of those textures, but with the same model data. Do I in essence have to load 5 of the six textures twice, one for each opengl rendering context? And the same for models? Can I share model's vertices across different views, but not necessarially render the same scene in each view? Thanks in advance...
