I understand it can be daunting at first. There are a few tutorials that might be useful, for instance Paul Martz's OSG Quick Start Guide, and the NPS tutorials which are on the Wiki now - see http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials . The latter even have a picking tutorial IIRC. > For instance, I didn't know that an > intersection was made directly with the Drawable, even though my instance > connected to the viewer is a MatrixTransform... A MatrixTransform does not have any geometry, so it cannot be intersected itself... The MatrixTransform has a child Geode, which contains a Drawable (ShapeDrawable in your case, but could be Geometry) and this is what actually checks if it was intersected (on the polygon level). Therefore, that is what is returned in the intersections list. Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [EMAIL PROTECTED] http://whitestar02.webhop.org/ ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
