Detailed Description

H I T

Information about where a ray hits the surface

Important Note: Surface Normals always point OUT of a solid.

Statement of intent: The hit_point and hit_normal elements will be removed from this structure, so as to separate the concept of the solid's normal at the hit point from the post-boolean normal at the hit point.
