[osg-users] Show part of geometry which intersects a specific area

[Robert Osfield]

Hi Ali,

One way of constraining rendering is to use osg::ClipNode - this
allows you to place one or more osg::ClipPlane (wrapper around
glClipPlane).  Have a look at the osgclip example, to run it use:

   osgclip cow.osgt
