Creating complex models with a transformation graph

A transformation graph is a forest of semantic transformations in which each node represents a tree of models. Combining all of these tree models produces a complex 3D model structure. The following image on the left-hand side shows a semantic model of the transformation. The right-hand side image shows a tree structure represented by each of the nodes in the semantic transformation graph:

Creating complex models with a transformation graph

Note

Transformation graphs use the parent-child relationship extensively. Without this, the transform graph hierarchy is very difficult to manage. A transformation graph represents node hierarchies, in which each ...
