virtualinherited 
Get the intersection of a ray with the object, including the hit time and the normal at the intersection point.
A negative time is returned if there was no intersection in the forward direction. If the normal cannot be computed, the zero vector is returned.
ray  The ray to test for intersection. 
max_time  Maximum allowable hit time, ignored if negative.

pure virtualinherited 
Get the time taken for a ray to intersect the object, or a negative value if there was no intersection in the forward direction.
All subclasses must reimplement this method. If the return value is negative, it should be at least
