Hi,over the weekend I have consolidated previous hacks to enable MRT into what I hope would be an acceptable patch for OSG.
I would like to have it tested a bit before sending it to submissions. Attached are the changes to OSG's Camera and RenderStage.Camera got a new method called setDrawBuffers (instead of the normal setDrawBuffer), which mirrors the OpenGL extension glDrawBuffers.
setDrawBuffers takes a vector of BufferComponents and this vector is then translated in RenderStage to a vector of GLenums that is passed to glDrawBuffers.
The new calls are orthogonal to current use cases, so hopefully no other code/examples would be affected.
The attached example shows sample usage. The example is very contrived, but I hope it explains the concept. I have some other examples that I can contribute later.
Please let fly with comments/observations. regards jpPS. How do I add an example to OSG? The CMakelists in the examples directory contains a list of directories, but when is the CMakelists in a specific example directory created?
