[ggt-devel] Patch Intersection.h

[Sebastian M. <seb...@gm...>]

Hi,

as I've written some weeks ago, I've fixed some float/double/ DATA_TYPE 
issues and  corrected some intersection functions, that were return 
false positives.

The changes in detail:

Line 318:
Fixed the box / lineseg intersection, which was missing an early out for 
the case were the ray hit the box. but the line didn't (some simple 
early out test by checking tin,tout between 0 and 1)

Lines 584, 616, 649, 706:

changed the declaration of tIN and tOUT parameters consitently to 
DATA_TYPE instead of fixed float.
addiditionally the numHits were mixed int/unsigned int which I've 
corrected to unsigned int everywhere

Line 745:
Same as above, double/float DATA_TYPE corrections
Here I've corrected the intersection test between plane an ray, that 
failed due to missing check in tIn/tOut - range

I've also added the proposed intersectDoubleSided-Test for ray/triangle, 
that ignores the triangle orientation.


cheers
