438 5954 d 22 h jrf /trunk/src/Geometry/ correcting a bug in placement of BSP planes and cleaning up a little bit  
436 5962 d 22 h jrf /trunk/src/Geometry/ closing files after use  
430 5973 d 18 h jrf /trunk/src/Geometry/ Minor correction to avoid numerical errors  
429 5973 d 18 h jrf /trunk/src/Geometry/ Improving ray-triangle intersection implementation and removing unnecessary static variables.  
428 5973 d 19 h jrf /trunk/src/Geometry/ Correcting major bug in BSPTree. It was clearing a vector and using it afterwards as if it hadn't been cleared. Unbelievable that we haven't seen problems because of this.  
426 5982 d 18 h jrf /trunk/src/Geometry/ introducing did_hit_diffuse  
423 5982 d 23 h jrf /trunk/src/Geometry/ initializing shininess by 0.0f instead of 0  
422 5990 d 10 h jrf /trunk/src/Geometry/ Removing unknown/unused/undocumented field "ran" from the Ray structure  
421 5990 d 11 h jrf /trunk/src/Geometry/ Updated Wavefront .mtl loading  
420 6001 d 20 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!)  
419 6001 d 20 h jrf /trunk/src/Geometry/ Introducing a function that applies a transformation matrix to a TriMesh  
417 6005 d 16 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.  
409 6101 d 19 h jrf /trunk/ bashing Visual Studio warnings  
404 6114 d 19 h jab /trunk/ Small changes  
385 6143 d 17 h jab /trunk/ CMakefiles included.

Note that exceptions were removed from Geometry/Polygonize.cpp since it did not play nice with visual studio 2005. An improved solution is needed so that the program does not just abort.		  
382 6149 d 22 h jab /trunk/ a number of fixes  
375 6162 d 17 h jrf /trunk/src/ Adding a homebrewed XmlParser and bashing the Expat dependency!  
373 6162 d 20 h jrf /trunk/ eliminating errors and warnings in VS 2005 compile  
371 6162 d 23 h jab /trunk/src/Geometry/ Ply loading was added to this Directory. Two files rply.c and rply.h which
expose an MIT licensed ply handling API have been introduced as well as
a ply_load function declared in ply_load.h and defined in ply_load.cpp		  
364 6270 d 13 h jrf /trunk/src/Geometry/ Corrections to have the ray tracer run properly in Visual Studio  
362 6305 d 10 h jab /trunk/src/ Some added documentation and also I added the tesselation routine  
357 6423 d 21 h jab /trunk/ A number of changes were made to quadric simplification  
354 6438 d 19 h awk /trunk/src/  
350 6451 d 17 h awk /trunk/ Worked around bug in BSPTree. "intersect_fast_node" does not work with
GCC!		  
349 6451 d 17 h awk /trunk/ Misc fixed to make it compile on ubuntu 7.10  
338 6527 d 23 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
334 6578 d 22 h jab /trunk/src/Geometry/ Slight changes to doc.  
330 6684 d 18 h jab /trunk/src/Geometry/ Some changes to the KDTree  
324 6705 d 22 h jab /trunk/src/ Some changes. Mostly a nasty precision issue has been fixed with regard
to 4x4 determinants. KDTrees have also been improved.		  
321 6713 d 11 h jab /trunk/ No log message.  
319 6721 d 12 h awk /trunk/src/Geometry/ Partitioned interface into public / private..
Changed all TriMesh* to const TriMesh*
Commented normal computation code in intersect in..
Fixed bug with normals (object space normals were returned, not world space)		  
318 6721 d 12 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
315 6726 d 22 h jab /trunk/ Some slight changes to QEM based decimation  
314 6759 d 23 h jrf /trunk/src/Geometry/  
313 6774 d 17 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.		  
311 6774 d 18 h jrf /trunk/src/Geometry/  
310 6774 d 19 h jrf /trunk/ BSPTree corrections  
309 6778 d 21 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
304 6780 d 21 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6792 d 20 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.
