Hi All,

So I have implemented a solution for my question below.  If the object returned is a segment I check to see if it is degenerate.  If it is I convert its source end to a point.  This seems to work ok.  However, I am still interested to know if this is the intended behavior or not?  Anyone have any thoughts?

Regards,

Matt

Hello,

I have a question regarding the Triangle_3_Segment_3_intersection function that is in CGAL3.5b1.  Should it ever return a degenerate Segment_3?  Seems like it should return a Point_3 instead.  Not sure if this is a bug, is the intended behavior, or I am doing something wrong. 

The situation that is giving me the degenerate segment is the intersection of a coplaner triangle and segment where the end of the segment is touching the edge of the triangle.

I can send a simple example if anyone is interested.

Thanks,

Matt
