FYI Bounding::sphere and bounding box both have ::contains( const vec3 vec ), both return true if the given point is within their volume

First check - see if its in the bounding sphere of the PAT Second check - go for the bounding boxes of the drawables. I guess I'll need to inverse transform my point by the PAT's matrix first? Anyway good to know it's not too difficult, Thank you, Andrew ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15633#15633 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
