rendering system is CPU-bound, or memory is particularly tight, this additional load
can decrease the frame rate and cut into the speedup provided by regulating level of

POLYGONAL MESHES
The essential concepts of LOD management apply to any model representation.
Polygonal meshes, splines, voxels, implicit surfaces, and even point- and image-based
representations are all compatible with the notions of static, continuous, and view-
dependent LOD. All of these representations are important for certain applications
or problem domains. ...
