Our application is a CAD-type app. Our domain objects already store their locations relative to other objects, so we thought it made sense to mirror that in our scene graph. Most of these transforms will not change from one frame to the next, only when the user adds/removes/moves an object, or at certain other times.
We also have a live video image provided by a real camera that we are projecting into the scene through projective texture mapping. It's important to maintain 20 fps for the video, not so much for the rest of the scene. Some of our domain objects are represented by 3D surfaces that we want the video projected onto. Others are overlay type objects that will not have the video texture applied to them. For each type of object, we have a single Geode that we then share between all the leaf MatrixTransforms corresponding to each object's location. For the sample graph in my earlier post, each of the 2000 subgraphs are initially identical. However at certain points in time one or more matrices in the subgraphs might change, so they would no longer be identical. We also need to be able to easily add or remove objects at any level at any time. ... Thank you!
