DESCRIPTION OF PROBLEM:
|
|
=======================
|
|
|
|
The sample map contains a wedge brush. The tip (the sharp edge) of the wedge
|
|
is chopped off by the YZ plane (side 5, or the last side, of the brush).
|
|
The height of the wedge where it is chopped is about 0.9. This makes it
|
|
barely smaller than DEGENERATE_EPSILON. So the face resulting from the chop
|
|
is probably degenerate, and that winding will be removed. I'm now wondering
|
|
what happens to the rest of the brush. 0.9 rounded to the nearest 1/8 unit
|
|
is 1/8, so the top face of the brush should get a slight raise, making the
|
|
"hole" even bigger. The sides will have degenerate edges near the chop, so
|
|
they will become triangles, creating open slivers in the sides.
|
|
|
|
Although this behavior is a tad nasty, it is expected based on the way the
|
|
code is written. I want to make sure nothing really nasty happens.
|
|
|
|
I consider this regression test to be broken if there is a "hole" in the brush,
|
|
and I consider this test to be very broken if something more drastic happens.
