Robert Osfield	d50eacd07e	From Paul Martz, "The changes are very similar to Magne's, except they now take the near plane into account. The changes are: ... * Change OcclusionQueryNode::getPassed to take a NodeVisitor rather than the distance from BS center to the eye point. Change where CullVisitor calls this method to use the new parameters. * getPassed now exits early and returns true to avoid blinking / blink-in of geometry for the first frame or for out-of-range LOD children coming back into view. * getPassed now considers the distance from the near plane to the bounding sphere (rather than eye point to bounding sphere) when determining if the viewer is "inside" the bounding sphere or not."	2010-02-26 10:13:28 +00:00

Robert Osfield	9d010e14fe	From Paul Martz, "his pretty much wraps up the OcclusionQueryNode work. I might make some additional modifications if testing reveals any issues, otherwise it's ready for 2.4."	2008-01-10 11:02:21 +00:00
Robert Osfield	b222d4201c	From Paul Martz, "The osgocclusionquery example contained some duplicate code that was also in the core OSG occlusion query code. This change removes the need for that."	2007-12-26 22:00:28 +00:00
