<p class="MsoNormal">I’m trying to figure out how to retrieve the combined matrix from a node that is of a PositionAttitudeTransform node type. I can get it converted to a Transform() class, but there is no clear way of getting the combined matrix from local
to world. For example,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Osg::PositionAttitudeTransform trans;<o:p></o:p></p>
<p class="MsoNormal">Trans.setScale(2,2,2);<o:p></o:p></p>
<p class="MsoNormal">Trans.setPosition(0,10,0);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Osg::Matrixd temp = getCombinedTransform(trans);<o:p></o:p></p>
<p class="MsoNormal">Osg::Matrixd getCombinedTransform(const osg::ref_ptr<osg::Node> & mat)<o:p></o:p></p>
<p class="MsoNormal">{<o:p></o:p></p>
<p class="MsoNormal"> Auto m = mat->asTransform();<o:p></o:p></p>
<p class="MsoNormal"> Return m->computeLocalToWorldMatrix (m, ???); << ====== why use a node visitor on yourself?<o:p></o:p></p>
