A solid 3D cone, whose base is a circular disk and apex is a point perpendicularly above the disk centre.
Definition at line 30 of file Cone3.hpp.
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.
- Parameters
-
| ray | The ray to test for intersection. |
| max_time | Maximum allowable hit time, ignored if negative. |
- Note
- The returned normal need not have unit length.

Get the time taken for a ray to intersect the object, or a negative value if there was no intersection in the forward direction.
