Re: [osg-users] Changing the value of a uniform during at scene graph traversal

Hi Matthew, Now, you can't change a uniform during a single OpenGL "traversal", of course (i.e., between glBegin() and glEnd()), but there is nothing stopping you from changing a uniform at any other time. If a single "object" is broken into several glBegin()/glEnd() sections for a given rend

[osg-users] Changing the value of a uniform during at scene graph traversal

I want to change the value of a uniform for the traversal of a subgraph. A the moment I am not sure how to do this. Does anyone have any suggestions on the easiest way to do this? Thanks, Roger ___ osg-users mailing list osg-users@lists.opensceneg
