342 6443 d 6 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 6487 d 12 h jab /trunk/ Added a ply viewer to OBJViewer.
other minor changes.		  
340 6506 d 11 h jab /trunk/GEL.xcodeproj/ Added ply view to OBJViewer  
339 6506 d 11 h jab /trunk/src/GLGraphics/ Added ply view to OBJViewer  
338 6506 d 11 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
337 6506 d 11 h jab /trunk/apps/OBJViewer/ Added ply view to OBJViewer  
336 6508 d 6 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.		  
335 6508 d 7 h jab /trunk/ A few changes to the project  
334 6557 d 10 h jab /trunk/src/Geometry/ Slight changes to doc.  
333 6595 d 22 h bj /trunk/apps/RangeScanViewer/ RangeScanViewer  
332 6627 d 1 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 6648 d 8 h jab /trunk/src/ Added a draw function for HMesh  
330 6663 d 6 h jab /trunk/src/Geometry/ Some changes to the KDTree  
329 6676 d 0 h jab /trunk/GEL.xcodeproj/ Added XCode files.  
328 6683 d 11 h jab /trunk/test/Geometry-kdtree/ Some changes to the kdtree test  
327 6683 d 11 h jab /trunk/src/CGLA/ Removed determinant from cpp file  
326 6683 d 11 h jab /trunk/test/CGLA-mat/ changes  
325 6683 d 12 h jab /trunk/src/CGLA/ An alternative 4x4 determinant function is included and commented out.  
324 6684 d 9 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 6690 d 3 h bj /trunk/src/CGLA/ added generic make_rot method with rotation matrix as input  
322 6691 d 22 h jab /trunk/apps/Raytracer/ Small changes to make ray tracer compile on mac  
321 6691 d 23 h jab /trunk/ No log message.  
320 6699 d 10 h awk /trunk/src/CGLA/  
319 6699 d 23 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 6699 d 23 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
317 6702 d 2 h awk /trunk/src/CGLA/  
316 6705 d 4 h jab /trunk/src/CGLA/ Added a constructor to Vec2i that accepts a single int.  
315 6705 d 9 h jab /trunk/ Some slight changes to QEM based decimation  
314 6738 d 10 h jrf /trunk/src/Geometry/  
313 6753 d 4 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.		  
312 6753 d 6 h jrf /trunk/apps/Raytracer/  
311 6753 d 6 h jrf /trunk/src/Geometry/  
310 6753 d 6 h jrf /trunk/ BSPTree corrections  
309 6757 d 9 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
306 6759 d 6 h jrf /trunk/ quaternion_cleanup branch has been merged with main branch  
305 6759 d 9 h jab /trunk/apps/ I have made minor changes to ensure things compile on Linux. Mostly
adding Makefiles		  
304 6759 d 9 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6771 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.		  
297 6771 d 10 h jrf /trunk/data/
