[osg-users] Re: How to realize volume rendering for medical use
I don't have time to look at your application right now, so have to provide some high level comments. The osgVolume NodeKit was written for volume rendering, and the effect you are looking for will be achievable with the right settings. First up the blending of the volume texels is done based on the alpha value, in your transfer function you have an alpha of 0.0 or 0.6, I'd recommend that you try a gradient to see what results you get. The OSG's tf plugin provides a native transfer function ascii file format that can help you set up and experiment with different transfer functions. the file format is in the form: # comment intensity r g b a intensity r g b a intensity r g b a You can pass in transfer functions to the osgvolume example via --tf myfile.tf -- You received this message because you are subscribed to the Google Groups "OpenSceneGraph Users" group.

What do you mean by "the transfer functions are too few"? What effect do you want?
