Re: [osg-users] Changes in osgVolume from 3.0 to 3.4

Robert, Thanks. This was helpful. I resolved my issue by just setting the alpha to 1.0 for all input values in my transfer function. This together with specifying an IsosurfaceProperty gave me the effect I wanted. Thanks again, Alex On Tue, Feb 16, 2016 at 10:16 AM Robert Osfield

Hi Igor, The description is useful. In general the OSG just passes along projection and view matrices directly to OpenGL. However, by default the OSG computes the near and far in the cull traversal on each frame and uses this to clamp the projection matrices so that depth precision is maximized.
