can someone help me with application in which I would like to draw objects from the same OpenGL context (let’s say 1 texture) in multiple windows (6) ?FYI I use dual NVidia video cards to have enough outputs on 1 computer.
I already tried to achieve that creating a single window taking the full outputs area and managing the rendering using viewport but I still have a black “glitch” appearing on my render and I hope to make it disappear rendering each output independently (the fact that window is overlapping the 2 video cards render areas could be the cause of this glitch ?) .
I can create 6 windows and a shared GL context but only one of the additionnal window can render, the other stays not rendered (even not cleared !). Should I create a shared context for each window ? Or can I use my shared context for all ?
Hope you can help, Regards
