Ideally you wouldn't need to determine the position of the top after rotation because they would all be positioned off of the same point, and then rotated together into place.
Either way, I found what caused the original code to not work; it was the order of transformations. The PositionAttitudeTransform applies the rotation first, and then applies the translation (imagine the cylinder rotating in place at the origin, and then moving itself into position). This means we want to set the position of the PositionAttitudeTransform to top_of_prev_rotated_cylinder instead of top_of_prev_unrotated_cylinder. That should do the trick. . .

If I were to set the pivot point of each cylinder to the bottom of each cylinder, how would I determine the top of the rotated cylinder? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59597#59597 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
