Howdy, I cannibalized the osgvolume example to do some volume rendering for my application.
The only function I changed was the main() function (primarily because it is not my main function, and my data has already been loaded). I only have one channel in my data, so I set desiredPixelFormat to GL_LUMINANCE. I ran into 2 problems: - alphaFuncValue seems to be ineffective. No matter what I set the alpha cut-off value to, I get the same results in my rendering. Blending is working, but it seems to behave as if alphaFuncValue is 0.0. - The corners of the volume get clipped off at certain angles. As a remedy, I pass a cube size of 1.5 to createCube() rather than 1.0. Is there a better solution? Thanks! And Kudos to the author (I think it was Robert) for making it so easy to get up and running w/ volume rendering.
