- The description of complex shapes (triangle meshes and face sets) in a
- scene graph would normally consists of separate nodes describing info
- like coordinates, normals, transformations and the shape node itself
- right?
-
- And during rendering traversal, different sets of elements in the
- rendering traversal state can be altered by the given class of nodes.
-
- My question is how can I gain access to information such as current
- coordinates after a transformation for example without computing it
- myself? since the traversal would already have done these calculations.
-
-
- Or do i have to access the coordinates directly from the coordinate node
- itself, determine the transformation from the SoTransform nodes and then
- perform the calculations.
-
- Please advice. Thanks
