Function intrSphereVsPlane
Checks sphere and plane for intersection
Example
Sphere sphere = Sphere(Vector3f(0, 0.9f, 0), 1.0f);
Plane plane = Plane(Vector3f(0, 1, 0), 0.0f);
Intersection isec = intrSphereVsPlane(sphere, plane);
assert(isec .fact);
assert(isConsiderZero(isec .penetrationDepth - 0.1f));
assert(isAlmostZero(isec .point - Vector3f(0.0f, -0.1f, 0.0f)));
assert(isAlmostZero(isec .normal - Vector3f(0.0f, 1.0f, 0.0f)));
