aramis_acg	f522143909	+ IFC: use custom triangulation algorithm to generate walls with openings. Introduce a configuration option to toggle the triangulation implementation. # IFC: fix bug in boolean clipping code leading to polygons having undefined normals. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@1006 67173fc5-114c-0410-ac8e-9d2fd5bffc1f	2011-05-18 18:08:18 +00:00
aramis_acg	c55509132b	- IFC: implement automatic conversion from polygons with holes to polygons that consist of only one piece and are thus applicable to triangulation by ear-cutting. This solves many of the broken windows that would fall victim to z-fighting in earlier revisions. - IFC: reduce logging overhead - Move parts of IFC and BLENDs logging code to a shared implementation. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@994 67173fc5-114c-0410-ac8e-9d2fd5bffc1f	2011-05-09 18:00:55 +00:00
aramis_acg	1400ae79e7	+ add first prototype version of the IFC-STEP loader. Loads many test models fine but does not support some of the more sophisticated format features. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@979 67173fc5-114c-0410-ac8e-9d2fd5bffc1f	2011-05-06 23:55:38 +00:00
