Thanks for answering Robert. I understand your position but I have already taken a look to the source code. The problem is that I very new to OSG & OpenGL programming, so it is difficult to me to understand it. Nevertheless, I can see on line 127 of TrackballDragger.cpp, this line of code:
Code: geode->addDrawable(createCircleGeometry(1.0f, 100)); So I think this is the line responsible for creating a fixed size sphere for the trackball. Also, I have noticed that this sphere looks immutable to other transformations, i.e., if I scale the object by using a tab box dragger, this sphere doesn't resize its radius up to the new bounding box. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=52707#52707 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
