I want to do something a little 'odd' and am not sure of the best way to do this. - assuming a 'large' number of (tri or quad) primitives in a primitiveset (say 100K-500K+) I want to hide ( not draw) a user-defined subset of those primitives.
- the user scenario is that the user selects a subset of primitives from the full geometry then "hides" them. The user can also "Un-hide" any hidden primitives at any time. - I could laboriously keep multiple geometries but was wondering if it is possible to override one of the drawing functions to "test" for membership in a hidden set for each primitive. Obviously this would follow the slow path, Or ???. I have looked at the primitiveset drawing code but got lost in the complexity of VBO vs displaylist vs slow path etc. Thanks Andrew ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20989#20989 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
