Visibly there's a misunderstanding on terminology here. I'm saying osg::BoundingBox is not restricted to a cube. It's a general AABB, meaning it can have different sizes in all three dimensions, but all aligned to the axes. For example: osg::Vec3 _min(-2, -6, -3); osg::Vec3 _max(1, -2, 64); means a bounding box of size (3, 4, 67). All three dimensions have different sizes. The center is (-0.5, -4, 30.5). I assume you were saying the same thing, and thus we're both arguing the same side of the argument :-) J-S -- ______________________________________________________ Jean-Sebastien Guay [EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ 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
