| class | CombineStaticTransformsVisitor |
| Combine Static Transform nodes that sit above one another. More... | |
| class | CopySharedSubgraphsVisitor |
| Copy any shared subgraphs, enabling flattening of static transforms. More... | |
| class | FlattenBillboardVisitor |
| Flatten MatrixTransform/Billboard pairs. More... | |
| class | FlattenStaticTransformsVisitor |
| Flatten Static Transform nodes by applying their transform to the geometry on the leaves of the scene graph, then removing the now redundant transforms. More... | |
