DESCRIPTION OF PROBLEM:
|
||||
=======================
|
||||
|
||||
Because of the coarse nature of SnapNormal(), planes that are 0.25 degrees
|
||||
away from being axial are "snapped" to be axial. The "normal epsilon"
|
||||
is a very small value by default, and cannot go much smaller (without
|
||||
running into limits of floating point numbers). The problem with
|
||||
SnapNormal() is that we compare the components of the normal that are near
|
||||
1, instead of comaring the components that are near 0. This leads to a very
|
||||
coarse and inaccurate SnapNormal().
|
||||
|
||||
If you open the example map in Radiant, you can see that the red brick should
|
||||
touch the middle checkered brick at the edge. However, once this map is
|
||||
compiled, the edges are a significant distance apart. This is due to the
|
||||
coarse and inaccurate nature of SnapNormal(). Likewise, the green brick should
|
||||
be flush with the center tiled brick, but it's not.
