342 6475 d 14 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 6519 d 20 h jab /trunk/ Added a ply viewer to OBJViewer.
other minor changes.		  
340 6538 d 19 h jab /trunk/GEL.xcodeproj/ Added ply view to OBJViewer  
339 6538 d 19 h jab /trunk/src/GLGraphics/ Added ply view to OBJViewer  
338 6538 d 19 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
337 6538 d 19 h jab /trunk/apps/OBJViewer/ Added ply view to OBJViewer  
336 6540 d 15 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 6540 d 16 h jab /trunk/ A few changes to the project  
334 6589 d 19 h jab /trunk/src/Geometry/ Slight changes to doc.  
333 6628 d 6 h bj /trunk/apps/RangeScanViewer/ RangeScanViewer  
332 6659 d 10 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 6680 d 16 h jab /trunk/src/ Added a draw function for HMesh  
330 6695 d 14 h jab /trunk/src/Geometry/ Some changes to the KDTree  
329 6708 d 9 h jab /trunk/GEL.xcodeproj/ Added XCode files.  
328 6715 d 20 h jab /trunk/test/Geometry-kdtree/ Some changes to the kdtree test  
327 6715 d 20 h jab /trunk/src/CGLA/ Removed determinant from cpp file  
326 6715 d 20 h jab /trunk/test/CGLA-mat/ changes  
325 6715 d 20 h jab /trunk/src/CGLA/ An alternative 4x4 determinant function is included and commented out.  
324 6716 d 18 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 6722 d 11 h bj /trunk/src/CGLA/ added generic make_rot method with rotation matrix as input  
322 6724 d 7 h jab /trunk/apps/Raytracer/ Small changes to make ray tracer compile on mac  
321 6724 d 7 h jab /trunk/ No log message.  
320 6731 d 18 h awk /trunk/src/CGLA/  
319 6732 d 8 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 6732 d 8 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
317 6734 d 10 h awk /trunk/src/CGLA/  
316 6737 d 12 h jab /trunk/src/CGLA/ Added a constructor to Vec2i that accepts a single int.  
315 6737 d 18 h jab /trunk/ Some slight changes to QEM based decimation  
314 6770 d 19 h jrf /trunk/src/Geometry/  
313 6785 d 13 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 6785 d 15 h jrf /trunk/apps/Raytracer/  
311 6785 d 15 h jrf /trunk/src/Geometry/  
310 6785 d 15 h jrf /trunk/ BSPTree corrections  
309 6789 d 17 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
306 6791 d 15 h jrf /trunk/ quaternion_cleanup branch has been merged with main branch  
305 6791 d 17 h jab /trunk/apps/ I have made minor changes to ensure things compile on Linux. Mostly
adding Makefiles		  
304 6791 d 17 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6803 d 16 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 6803 d 18 h jrf /trunk/data/
