Class Collision3
- Namespace
- GeometryHelper.Core
- Assembly
- GeometryHelper.dll
Provides static methods for deciding whether two 3D shapes overlap.
CollidesWith answers yes or no and says nothing about where. Shapes that merely touch count
as colliding, so the answer agrees with Distance3 reporting zero for the same pair. Where
the shapes meet is Intersection3, and how far apart they are when they do not is
Distance3.

Remarks
A segment, a ray and a flat region have no thickness between them, so there is nothing for them to overlap in: they touch exactly where they cross. Each of these is therefore the crossing test with the point thrown away, which is worth having under its own name because a caller who only wants to know whether they meet should not have to declare somewhere to put an answer it will not read.
A ray against a box is the one that needs a second question. A box is bounded, so a ray that starts inside it always leaves and does cross the surface — but a ray starting on the inside is the case a crossing count is least sure of, so where it starts is asked first, as it is for a ray against a solid.
