Characterization	back to summary
pack-priv Characterization(final BSPTree<S> node, final SubHyperplane<S> sub) Simple constructor. Characterization consists in splitting the specified sub-hyperplane into several parts lying in inside and outside cells of the tree. The principle is to compute characterization twice for each cut sub-hyperplane in the tree, once on the plus node and once on the minus node. The parts that have the same flag (inside/inside or outside/outside) do not belong to the boundary while parts that have different flags (inside/outside or outside/inside) do belong to the boundary. Parameters node:BSPTree<S> current BSP tree node sub:SubHyperplane<S> sub-hyperplane to characterize

Characterization

back to summary

pack-priv Characterization(final BSPTree<S> node, final SubHyperplane<S> sub)

Simple constructor.

Characterization consists in splitting the specified sub-hyperplane into several parts lying in inside and outside cells of the tree. The principle is to compute characterization twice for each cut sub-hyperplane in the tree, once on the plus node and once on the minus node. The parts that have the same flag (inside/inside or outside/outside) do not belong to the boundary while parts that have different flags (inside/outside or outside/inside) do belong to the boundary.

Parameters

node:BSPTree<S>: current BSP tree node
sub:SubHyperplane<S>: sub-hyperplane to characterize
