Hi Chris
This can be done with a shader and a framebuffer.
ok, so I'll try again using shaders (If anyone have more infos about that, I'm listenning)
The gemwin is not the way to do it because it knows nothing of the geometry being rendered elsewhere in a patch.
Ok, I thought about [gemwin] because of the way we can move the viewpoint in the scene using [view< messages. And camera location + camera focus managed with the same object [gemwin] would have been nice... Best regards,
Pierre
