DESCRIPTION OF PROBLEM:
|
||
|
|
=======================
|
||
|
|
|
||
|
|
In the disappearing_triangle regression test I outlined a potential problem
|
||
|
|
in the tjunction.c code, having to do with 2 points being too close together
|
||
|
|
on a winding, and that winding becoming invalid (drawsurf disappearing).
|
||
|
|
|
||
|
|
This example map is the same as disappearing_triangle.map, except that the
|
||
|
|
floor is raised by 1 unit. Therefore the floor intersects the sliver triangle.
|
||
|
|
The resulting chopped sliver has a very short edge that is "degenerate" and
|
||
|
|
causes that draw surf to go away due to problems in the tjunction.c code.
|
||
|
|
|
||
|
|
This is speculation at this point. I will provide more info after the bug has
|
||
|
|
been fixed.
