341 6474 d 6 h jab /trunk/ Added a ply viewer to OBJViewer.
other minor changes.		  
340 6493 d 5 h jab /trunk/GEL.xcodeproj/ Added ply view to OBJViewer  
339 6493 d 5 h jab /trunk/src/GLGraphics/ Added ply view to OBJViewer  
338 6493 d 5 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
337 6493 d 5 h jab /trunk/apps/OBJViewer/ Added ply view to OBJViewer  
336 6495 d 1 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 6495 d 2 h jab /trunk/ A few changes to the project  
334 6544 d 5 h jab /trunk/src/Geometry/ Slight changes to doc.  
333 6582 d 17 h bj /trunk/apps/RangeScanViewer/ RangeScanViewer  
332 6613 d 20 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 6635 d 2 h jab /trunk/src/ Added a draw function for HMesh  
330 6650 d 0 h jab /trunk/src/Geometry/ Some changes to the KDTree  
329 6662 d 19 h jab /trunk/GEL.xcodeproj/ Added XCode files.  
328 6670 d 6 h jab /trunk/test/Geometry-kdtree/ Some changes to the kdtree test  
327 6670 d 6 h jab /trunk/src/CGLA/ Removed determinant from cpp file  
326 6670 d 6 h jab /trunk/test/CGLA-mat/ changes  
325 6670 d 7 h jab /trunk/src/CGLA/ An alternative 4x4 determinant function is included and commented out.  
324 6671 d 4 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 6676 d 22 h bj /trunk/src/CGLA/ added generic make_rot method with rotation matrix as input  
322 6678 d 17 h jab /trunk/apps/Raytracer/ Small changes to make ray tracer compile on mac  
321 6678 d 18 h jab /trunk/ No log message.  
320 6686 d 4 h awk /trunk/src/CGLA/  
319 6686 d 18 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 6686 d 18 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
317 6688 d 21 h awk /trunk/src/CGLA/  
316 6691 d 22 h jab /trunk/src/CGLA/ Added a constructor to Vec2i that accepts a single int.  
315 6692 d 4 h jab /trunk/ Some slight changes to QEM based decimation  
314 6725 d 5 h jrf /trunk/src/Geometry/  
313 6739 d 23 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 6740 d 1 h jrf /trunk/apps/Raytracer/  
311 6740 d 1 h jrf /trunk/src/Geometry/  
310 6740 d 1 h jrf /trunk/ BSPTree corrections  
309 6744 d 3 h jab /trunk/ numerous changes making ray tracing work with bbox hierarchy  
306 6746 d 1 h jrf /trunk/ quaternion_cleanup branch has been merged with main branch  
305 6746 d 3 h jab /trunk/apps/ I have made minor changes to ensure things compile on Linux. Mostly
adding Makefiles		  
304 6746 d 3 h jab /trunk/src/ I have made minor changes to ensure that GEL compiles on Linux.  
299 6758 d 3 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 6758 d 4 h jrf /trunk/data/  
295 6758 d 4 h jrf /trunk/src/Geometry/
