Point and plane
We have seen the plane equation before; a point is on a plane if the result of the plane equation is 0. To find the point on the plane closest to a test point, we must project the test point onto the normal of the plane. We then subtract this new vector from the test point to get the closest point:
Getting ready
We are going to implement two functions. The first function will test whether a point is on the surface of a plane using the plane equation. The second function will find the point on a plane closest to a given test point.
How to do it…
Perform the following steps to implement point tests for a plane:
- Declare
