Intersection failed with RTC_GEOMETRY_TYPE_DISC_POINT
I made some tests with geometry of type RTC_GEOMETRY_TYPE_DISC_POINT and i found a weird behavior when a ray start to close to a primitive.
For exemple, if 2 points are close ( inferior to the point size ) and i start a ray just after the first intersected primitive, the second is never intersected until the distance between the both point are larger than the bounding box ( i guess )
I suppose that if a ray starts inside the bounding box of a RTC_GEOMETRY_TYPE_DISC_POINT primitive, it is ignored.
This is problematic if i want to test occlusion between point and a close triangle mesh for example.
