| Isis::BulletAllHitsRayCallback::BulletAllHitsRayCallback | ( | ) |
Default constructor.
The ray beginning and end default to the origin. The intersections vector defaults to empty.

| ) |
Construct a callback with a ray start and ray end.
| observer | The beginning of the ray. |
| lookdir | The end of the ray. |
| cullBackfacers | If back facing intersections should be culled. |

Add a local intersection result to this callback during ray casting.
| rayResult | The local intersection result for the ray cast. |
| normalInWorldSpace | If the normal stored in the local result is in local coordinates or world coordinates. |
