Looking over the Performance tips for Java 3D at
http://tintoy.ncsa.uiuc.edu/~srp/java3d/perf_guide.html
there is an item which reads:
------------------------
Change Number of Shape3D Nodes
In the current implementation there is a certain amount of fixed overhead
associated with the use of the Shape3D node. In general, the fewer Shape3D
nodes that an application uses, the better. However, combining Shape3D nodes
without factoring in the spatial locality of the nodes to be combined can
adversely effect performance by effectively disabling view frustum culling.
An application programmer will need to experiment to find the right balance
of combining Shape3D nodes while leveraging view frustum culling.
------------------------
I don't understand what this means. I use a lot of Shape3D objects. How
else do you define geometric objects in Java 3D??
What does "...combining Shape3D nodes...." mean? Is there a way to combine
several Shape3D objects into a single Shape3D object?
