typedef GLfloat Point[3]


Points represent locations in space, based on some (unspecified) coordinate system.

Allowed Logical Operations

Distance Between Two Points
point_distance_to(p1, p2) computes the distance between two points.
Displacement between two points
point_diff(&v, p1, p2) computes the displacement vector v from point p1 to point p2
Test to see if point is in Sphere?
point_is_in_sphere(s,p) returns a true value if the point p is within the sphere s
