HI Vincent,
I can't really work out exactly what the problem you have, I presume
others too had a problem understanding what the issue you have is as
otherwise others would have posted a reply...
My best guess is that you are confusing what getWorldMatrices()
provides... if so please just read the doxygen docs for it...
/** Get the list of matrices that transform this node from
local coordinates to world coordinates.
* The optional Node* haltTraversalAtNode allows the user to
prevent traversal beyond a specifed node. */
MatrixList getWorldMatrices(osg::Node* haltTraversalAtNode=0) const;
Please note, WorldMatrices is not local matrices, its exactly what it
says. local matrices and world matrices only every coincide when you
have now transforms in your parental path.
Robert.
