417 5949 d 6 h jrf /trunk/ Introducing gel_rand: a speed-optimized linear congruential pseudo-random number generator. It has been placed in CGLA.h. And all references to rand, srand, and RAND_MAX have been changed to gel_rand, gel_srand and GEL_RAND_MAX.  
324 6649 d 12 h jab /trunk/src/ Some changes. Mostly a nasty precision issue has been fixed with regard
to 4x4 determinants. KDTrees have also been improved.		  
318 6665 d 2 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
313 6718 d 7 h jrf /trunk/ BSPTree ray tracing now works well !
The problem was a way too large epsilon causing triangles to appear unnecessarily in several different space division boxes. Precision has now been increased and the code has been made more robust. Try it out on the bunny.		  
310 6718 d 9 h jrf /trunk/ BSPTree corrections  
309 6722 d 11 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
304 6724 d 11 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6736 d 10 h jrf /trunk/ The SPD branch has been merged with the main branch.
This means that Bounding Box Hierarchies, BSP Trees, and two new applications have been added.		  
294 6736 d 13 h jrf /  
290 6738 d 12 h jrf /branches/SPD/src/Geometry/ Andreas' Bounding Box Hierarchies have been added  
208 7030 d 12 h jrf /branches/SPD/src/Geometry/ Adding Bent's BBox, BSPTree, and Ray. Rewritten to fit the TriMesh class in Geometry.
