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 tried to cast the result of
getCore() to obtain a TransformPtr but it's not working...
For the cast you have to use the static dcast method. 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.
