460 5698 d 14 h jab /trunk/src/Geometry/ Some performance improvement to bbox trees.  
451 5866 d 18 h jrf /trunk/src/Geometry/ the golden middle way with respect to precision for ray-triangle intersection distance check  
450 5873 d 15 h jrf /trunk/src/Geometry/ increasing precision for ray-triangle intersection distance check  
443 5889 d 13 h jab /trunk/src/Geometry/ Fixed all of the include guards so that they follow the standard where both directory and file name are part of the guard name  
440 5889 d 14 h jab /trunk/src/Geometry/ Load functions which allow for loading of several types depending on extension  
438 5907 d 16 h jrf /trunk/src/Geometry/ correcting a bug in placement of BSP planes and cleaning up a little bit  
436 5915 d 16 h jrf /trunk/src/Geometry/ closing files after use  
430 5926 d 11 h jrf /trunk/src/Geometry/ Minor correction to avoid numerical errors  
429 5926 d 12 h jrf /trunk/src/Geometry/ Improving ray-triangle intersection implementation and removing unnecessary static variables.  
428 5926 d 13 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 5935 d 12 h jrf /trunk/src/Geometry/ introducing did_hit_diffuse  
423 5935 d 17 h jrf /trunk/src/Geometry/ initializing shininess by 0.0f instead of 0  
422 5943 d 4 h jrf /trunk/src/Geometry/ Removing unknown/unused/undocumented field "ran" from the Ray structure  
421 5943 d 4 h jrf /trunk/src/Geometry/ Updated Wavefront .mtl loading  
420 5954 d 14 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 5954 d 14 h jrf /trunk/src/Geometry/ Introducing a function that applies a transformation matrix to a TriMesh  
417 5958 d 10 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 6054 d 13 h jrf /trunk/ bashing Visual Studio warnings  
404 6067 d 13 h jab /trunk/ Small changes  
385 6096 d 11 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 6102 d 16 h jab /trunk/ a number of fixes  
375 6115 d 11 h jrf /trunk/src/ Adding a homebrewed XmlParser and bashing the Expat dependency!  
373 6115 d 14 h jrf /trunk/ eliminating errors and warnings in VS 2005 compile  
371 6115 d 17 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 6223 d 7 h jrf /trunk/src/Geometry/ Corrections to have the ray tracer run properly in Visual Studio  
362 6258 d 4 h jab /trunk/src/ Some added documentation and also I added the tesselation routine  
357 6376 d 14 h jab /trunk/ A number of changes were made to quadric simplification  
354 6391 d 13 h awk /trunk/src/  
350 6404 d 10 h awk /trunk/ Worked around bug in BSPTree. "intersect_fast_node" does not work with
GCC!		  
349 6404 d 11 h awk /trunk/ Misc fixed to make it compile on ubuntu 7.10  
338 6480 d 17 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
334 6531 d 16 h jab /trunk/src/Geometry/ Slight changes to doc.  
330 6637 d 12 h jab /trunk/src/Geometry/ Some changes to the KDTree  
324 6658 d 16 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 6666 d 5 h jab /trunk/ No log message.  
319 6674 d 5 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 6674 d 5 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
315 6679 d 16 h jab /trunk/ Some slight changes to QEM based decimation  
314 6712 d 16 h jrf /trunk/src/Geometry/  
313 6727 d 11 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.
