426 5924 d 22 h jrf /trunk/src/Geometry/ introducing did_hit_diffuse  
422 5932 d 14 h jrf /trunk/src/Geometry/ Removing unknown/unused/undocumented field "ran" from the Ray structure  
420 5944 d 0 h jrf /trunk/src/Geometry/ Introducing a function that retrieves the hit material from a traced ray. And switching from tab to space indentation (we should do this for all files! Spaces look nice in all editors!)  
417 5947 d 20 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 6648 d 2 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 6663 d 15 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
313 6716 d 21 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 6716 d 23 h jrf /trunk/ BSPTree corrections  
309 6721 d 1 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
304 6723 d 1 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6735 d 0 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 6735 d 2 h jrf /  
290 6737 d 2 h jrf /branches/SPD/src/Geometry/ Andreas' Bounding Box Hierarchies have been added  
208 7029 d 1 h jrf /branches/SPD/src/Geometry/ Adding Bent's BBox, BSPTree, and Ray. Rewritten to fit the TriMesh class in Geometry.
