ulf ad9d178f0a - Bugfix: IfcLoader lost nodes and geometry when they were stored in subnodes of IfcSpace and the setting "Filter IfcSpace" was enabled 2015-03-13 15:13:53 +01:00
Alexander Gessler f6f8462113 Update IfcLoader to use numeric_limits<uint32_t> instead of UINT32_MAX, fixes gcc build and is more consistent with the rest of the codebase. Fixes #471. 2015-02-28 13:40:10 +01:00
ulf b71ded1ad0 - manually merged C4D importer code from acgessler branch 
- manually merged IFC bugfixes and improvements from schrompf branch

George Papadopoulos 5ef8c09dbb Use AiNode's metadata to keep per-node(and per-instance) FBX (3dsmax) UserDefinedProperties 
Also simplify metadata structure to avoid unnecessary allocations (and make it easier for wrappers like AssimpNET to read it)

aramis_acg 81ad224f84 - IFC: Refactor source to simplify maintenance. 
- IFC: rate all available representations by a simple ranking system and take the one that is easiest to load. This should avoid loading the same geometry twice. Also it might result in quality improvements when BRep geometry is avoided in favour of extrusion geometry.
# IFC: Various bugfixes related to geometry loading.

aramis_acg 1e2dd3eefc - IFC: use smart pointers to keep STEP-SELECT entities in the converted output data structures. This allows us to free the original parameter tuples early as ownership of their members can be transferred. This cuts down memory overhead to 8x (assuming a typical x64 builds) and reduces loading time on average by ~5% as measured on my system.

aramis_acg d467b5bb27 # improve robustness of IFC loader: filter out duplicate points, adjacent colinear edges, silently ignore zero-vertex polygons. fix various small bugs and improve numeric stability of some code segments. 
- workaround: silently drop very small nested polygon boundaries to avoid cases where a large polygon brep (i.e. a slab) has extremely holes that are so extremely small in comparison to the dimensions of the outer polygon that the resulting numeric accuracies make the triangulation fail. I guess the ultimate solution would be a delauney triangulator with extremely high numeric stability, however this is difficult to achieve.

aramis_acg 78b44c3aed - IFC: slight optimization, take less memory. 
# IFC: try to make normals point outwards, if possible.
# IFC: implement recursive polygon merging, but leave it disabled since it seems to fail on very complicated polygons with multiple, nested boundaries.

aramis_acg bbd7547fff - Further work on IFC, fix transformations, support non-uniform transformations, optimize loading, use recursive algorithm to resolve holes in polygons, implement CSG logic to generate wall openings. The latter is currently disabled. 
- Triangulation step now automatically drops polygons with an area of zero.
- Add debug preprocessor switch to dump all triangulations to a separate file.
- Refactoring, collect some polygon related functions in a separate header, PolyTools.h

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.
