Hi Yes the hierarchy looks OK _____

Hi, Gordon and Vincent! Thanks for answering my question. I designed as following. class XGLink : public osg::MatrixTransform { . } After that, I wanna add some drawables into XGLink. But XGLink is not a Geode. (osg::Drawable is can be add to only Geode) So, I need to addChild (new Geode) into XGLink. And I addDrawable osg::Drawable to the new Geode. [ hierarchy ] XGLink (osg::Group) | XGLinkGeode (osg::Geode) | XGDrawable (osg::Drawable) Is this correct? Ps. I cannot speak English so well. Please understand me J Ps. How to reply again to reply?

If you want to change the position / orientation of this node and its children as in a shoulder of an arm then is really HAS to be a transformation node and not a basic group or node What's is the issue with using a transform node for what it is designed to do ? _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vincent Bourdier Sent: Tuesday, May 06, 2008 9:28 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Some 'osg::Geode' that can be transformed should bemade as 'osg::MatrixTransform'? Hi, osg::group inherit from osg::node, so a group is a node. Is it your question ? or it is more complicated ? 2008/5/6 Jeongseok Lee <[EMAIL PROTECTED]>: Hi all. This is my first question to all of you. So, it's very naive question. J I'm developing 3D robot dynamics simulator. There are links of robot in that simulator. And the links can move (transform). So I used 'osg::MatrixTransform'. But this a kind of osg::Group. I wanna make link as 'osg::Node'. How am I suppose to do? ================================================================ Jeongseok Lee MS Candidate Robotics Laboratory School of Mechanical & Aerospace Engineering Seoul National University Tel : +82-2-880-7149 Cell : +82-10-8958-3791 E-mail : [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
