367 6185 d 3 h jab /trunk/ Slight changes to quadric simplification. I made the interface a little saner.  
366 6185 d 7 h jab /trunk/src/CGLA/ So a variable l has now been given a default value to protect against
warnings		  
364 6262 d 20 h jrf /trunk/src/Geometry/ Corrections to have the ray tracer run properly in Visual Studio  
363 6293 d 0 h jab /trunk/ A few changes to make quadric simplification better. In particular, boundaries
are now handled well.		  
362 6297 d 17 h jab /trunk/src/ Some added documentation and also I added the tesselation routine  
359 6411 d 18 h jab /trunk/src/CGLA/ Added 3D matrix functions for transformations  
358 6411 d 18 h jab /trunk/src/CGLA/ added rotation and scaling matrices to 3d double matrices  
357 6416 d 4 h jab /trunk/ A number of changes were made to quadric simplification  
354 6431 d 2 h awk /trunk/src/  
351 6432 d 18 h jab /trunk/ some bug fixes  
350 6444 d 0 h awk /trunk/ Worked around bug in BSPTree. "intersect_fast_node" does not work with
GCC!		  
349 6444 d 0 h awk /trunk/ Misc fixed to make it compile on ubuntu 7.10  
346 6444 d 2 h awk /trunk/  
344 6457 d 1 h jab /trunk/ The power eigensolution method was slightly broken. It seems to work now.  
342 6457 d 1 h jab /trunk/src/CGLA/ The power eigensolution method was slightly broken. It seems to work now. The test program has been improved. However, it is a simple method, and only robust on small matrices but that is what CGLA is all about  
341 6501 d 7 h jab /trunk/ Added a ply viewer to OBJViewer.
other minor changes.		  
339 6520 d 6 h jab /trunk/src/GLGraphics/ Added ply view to OBJViewer  
338 6520 d 6 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
336 6522 d 2 h jab /trunk/ Ensured that the touched value is unchanged when saving
more work to do:
In many places, I change touch values, and probably all
these should be changed so that they restore the value.		  
334 6571 d 5 h jab /trunk/src/Geometry/ Slight changes to doc.  
332 6640 d 21 h jab /trunk/src/HMesh/ Added functions for subdividing (Catmull Clark topological splits - but
not averaging) and closing holes simply by turning holes into boundary
polygons.		  
331 6662 d 3 h jab /trunk/src/ Added a draw function for HMesh  
330 6677 d 1 h jab /trunk/src/Geometry/ Some changes to the KDTree  
327 6697 d 7 h jab /trunk/src/CGLA/ Removed determinant from cpp file  
325 6697 d 7 h jab /trunk/src/CGLA/ An alternative 4x4 determinant function is included and commented out.  
324 6698 d 5 h jab /trunk/src/ Some changes. Mostly a nasty precision issue has been fixed with regard
to 4x4 determinants. KDTrees have also been improved.		  
323 6703 d 22 h bj /trunk/src/CGLA/ added generic make_rot method with rotation matrix as input  
321 6705 d 18 h jab /trunk/ No log message.  
320 6713 d 5 h awk /trunk/src/CGLA/  
319 6713 d 19 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 6713 d 19 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
317 6715 d 21 h awk /trunk/src/CGLA/  
316 6718 d 23 h jab /trunk/src/CGLA/ Added a constructor to Vec2i that accepts a single int.  
315 6719 d 5 h jab /trunk/ Some slight changes to QEM based decimation  
314 6752 d 6 h jrf /trunk/src/Geometry/  
313 6767 d 0 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 6767 d 2 h jrf /trunk/src/Geometry/  
310 6767 d 2 h jrf /trunk/ BSPTree corrections  
309 6771 d 4 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
306 6773 d 2 h jrf /trunk/ quaternion_cleanup branch has been merged with main branch
