i transform linkage of bars (cuboids linked via joints), using transformation matrices in opengl. if linkage structure tree, can transform fine, fixing 1 part, setting root of tree, each part, transformation matrix of part own local transformation multiplied transformation matrices of ancestors root.
however, don't know how this, if linkage structure graph has cycles. mean node might have multiple parents, how can describe transformation matrix of node has multiple parents in terms of of ancestors in graph root?
