313 6741 d 5 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 6741 d 7 h jrf /trunk/src/Geometry/  
310 6741 d 7 h jrf /trunk/ BSPTree corrections  
309 6745 d 9 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
306 6747 d 7 h jrf /trunk/ quaternion_cleanup branch has been merged with main branch  
304 6747 d 9 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6759 d 8 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.		  
295 6759 d 10 h jrf /trunk/src/Geometry/  
277 6839 d 11 h jrf /trunk/src/ The int_pow function in CGLA has been updated to run with O(log(n)) complexity.

The QuatTrackBall has been updated.		  
271 6853 d 8 h bj /trunk/ removed .vcproj and .sln files from SVN  
248 6899 d 9 h bj /trunk/src/CGLA/  
230 6937 d 7 h bj /trunk/src/Geometry/ resolving jab sloppyness ;-)  
229 6937 d 7 h bj /trunk/src/HMesh/ warnings removed  
223 6943 d 9 h bj /trunk/ resolved LIBC default lib issue with a #pragma
clapack.lib needs to have libc ignored		  
222 6955 d 5 h jab /trunk/src/ minor changes  
220 6955 d 7 h jab /trunk/ Fixed QEM problems  
219 6955 d 9 h bj /trunk/src/HMesh/ #include "Util/BinaryHeap.h" removed  
215 6956 d 7 h jab /trunk/src/HMesh/ Our version of QSlim has been greatly improved. It now performs
consistency checks to avoid bad edge collapses which will flip
triangles. Another fixed problem was a voracious memory hunger.

Fuzzy vector median smoothing has been added.

Other changes are minor.		  
214 6956 d 7 h jab /trunk/src/Geometry/ Load raw can now load a signed short volume
Elsewhere Vec3d has replaced Vec3f		  
211 7045 d 7 h jab /trunk/src/ Removed IMesh from documents  
206 7053 d 10 h jrf /trunk/src/CGLA/ Added a constructor to Vec3f taking a Vec4f as argument. The last element of the Vec4f is simply thrown away.

Added a Vec2ui. A 2D vector of unsigned integers is useful for specifying dimensions.		  
204 7089 d 10 h jrf /trunk/src/GLGraphics/ Minor bug corrected with respect to zero rotation  
203 7092 d 11 h jrf /trunk/src/Geometry/ pragmas corrected  
198 7096 d 9 h bj /trunk/ Added Visual Studio 2005 compatibility  
197 7097 d 8 h jrf /trunk/src/CGLA/ Redefinition of CGLA::isnan to have better cross platform support  
196 7097 d 8 h jrf /trunk/src/CGLA/ cgla_nan() has been corrected. A minor bug caused it to return 0.0 rather than nan ...  
195 7097 d 11 h jrf /trunk/ warning pragmas corrected.
Added messages stating that some preprocessor directives are needed for HMesh to work with MSVC8.		  
192 7103 d 10 h jab /trunk/ I made some changes to the polygonizer.  
191 7103 d 12 h jab /trunk/ So some changes have been made. Things are partly foobar in the volume
polygonizer and the trilinfilter. There is a dilemma - it is hard to
allow trilinear interpolation of vectors while disallowing gradient
computation of unsigned entities.		  
190 7113 d 11 h bj /trunk/ updated vcproj/sln files  
189 7116 d 4 h jab /trunk/ Fixed a bad bad bug in Mat3x3f - some fields in generated rotation
matrices were undefined.

The Makefile now works on Linux - it should be made to work on at least
OSX and Linux - the problem is the shared libs.		  
188 7117 d 22 h bj /trunk/src/CGLA/ fixed merge error  
186 7124 d 5 h jab /trunk/src/ Fixed a bug in gel_glut.h and made TrilinFilter more portable.  
184 7124 d 10 h jab /trunk/src/Geometry/ Some changes to the trilinfilter. For instance, the gradient can now be
computed.		  
183 7124 d 10 h jab /trunk/src/HMesh/ Some restructuring. fair_polygonize (h and cpp) have been removed.
The contents is now in volume polygonizei. Mostly minor changes
elsewhere.		  
182 7130 d 12 h bj /trunk/ merged restructuring branch properly  
178 7131 d 6 h bj /trunk/ merged restructuring branch  
171 7134 d 11 h bj /trunk/src/CGLA/ added make_rot(Mat4x4f)  
166 7145 d 5 h bj /trunk/src/HMeshUtil/  
165 7145 d 5 h bj /trunk/src/HMeshUtil/
