Yes, I already know it. All is working fine now: thank you for you help, I really appreciates :) JA -----Message d'origine----- De : Christoph Fuenfzig [mailto:[EMAIL PROTECTED] Envoyé : 8 mars 2005 13:56 À : [email protected] Objet : Re: [Opensg-users] Local transform matrix of a parent node Hi, Jacques-André Boulay wrote: >Hi, > >I have a simple question for you: how can I obtain the local >transformation matrix of the parent node of a node? > >I tried to call getParent() first to obtain the parent node of my >node, but I don't know how to extract the transform node from it >since getCore() return a NodeCorePtr that is not directly >compatible with a TransformPtr.

I always use TransformPtr trf = TransformPtr::dcast(node->getCore()); If the result is NullFC then it is not a Transform and you have to go further up the tree... Do you know the method Matrix getToWorld() of Node? It gives you the accumulated matrix in the node.
