Abstract:
Many renderers perform poorly on scenes that contain a lot of detailed
geometry. Level-of-detail techniques can alleviate the load on the
renderer by creating simplified representations of primitives that are
small on the screen. Current methods work well when the detail is due
to the complexity of the individual elements, but not when it is due
to the large number of elements. In this paper, we introduce a
technique for automatically simplifying this latter type of geometric
complexity. Some elements are pruned (i.e., eliminated), and the
remaining elements are altered to preserve the statistical properties
of the scene.
