Chapter 8. 3D Point Tests
Now that we have some 3D primitives defined, it's time to implement some simple point tests for them. In this chapter, we are going to implement the following point-related test functions:
- Point contained in sphere
- Closest point on sphere
- Point contained in AABB
- Closest point on AABB
- Point contained in OBB
- Closest point on OBB
- Point on surface of plane
- Closest point on plane
- Point on line segment
- Closest point along line
- Point on ray
- Closest point along ray
Introduction
For each primitive (other than the point) we will implement two test functions. The first function will tell us if a point is located inside or on the surface of a primitive. The second test will tell us what the closest point on the primitive is to a test point.
