blender loader no longer produces randomized output in some scenarious. nice side effect of less asthetic diversity: less segfaults.
assimpview is no longer topmost.

- don't leak LogStreamInfo when detaching streams from DefaultLogger.
- detach the stream before deleting it in aiDetachAllLogStreams.
Thanks to Bart Botta for the patch.
- DefaultLogger does not properly delete log streams if they're still attached to it when the logger is destroyed. This is the behaviour specified in the documentation.
- Adapt AssimpView's logger usage, which didn't follow the spec as well.

git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@243 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
3DS: Fixed transformation problems (Pivot points), added WIP animation support. No target animation yet (cameras, spot lights). Not yet fully tested, but static models that worked before should still work now, except all look correct now :-) (some problems with very large models remaining)
Further work on the IRR and IRRMESH loaders. IRR still WIP, IRRMESH more stable now.
Work on the LWo loader. Added support for the "one-layer-only" mode. Hierarchy bug still unfixed, UV coords bug still unfixed.
Further work on the FindInvalidDataprocess. Improved validation for normals, no false positives anymore.
Further work on the MDR loader, still WIP.

git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@236 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Added lightmap viewing support to the viewer. Irrlicht's tone scaling is hardcoded for the moment, a proper implementation will follow with the new viewer.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@232 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
- made HasFooBar()-checks more precise on the way

git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@211 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Fixed normal vector handling in the ASE loader. Improved animation & camera & light support - as for the 3DS Loader, still in the works.
Fixed AC - Loader. It is now able to load models with complex hierarchies correctly. Added a small workaround for Quick3D, which writes invalid AC files.
DXF-Loader skips {...} blocks produced by 3DS Max & AutoCad correctly now.
DefaultLogger doesn't repeat identical log messages now.
FindInvalidData-Process removes empty or dummy animation tracks now.
LWO-Loader recognizes complex shaders (such as Fresnel) correctly now. Other LLWO bugs still unsolved.
Fixed bugs in the Ply parser, causing non-triangular faces to crash.
Added some additional helperutilities to StreamReader.
Fixed a bug in ProcessHelper.h causing SPlitLargeMeses and SortBxPType to crash for meshes containing many bones.
Changed OB default material from black to gray.
Added additional test fils: ply (bugfix), ase (animation), QUick3D & Irr (in the works), STL (export from 3DS Max)
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@210 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Fixed a bug that caused the viewer to render "random" polygons in some special cases.
ASE: Added parsing support for *GROUP nodes. Improved light & camera handling (still WIP). Fixed a bug that was caused by a recent change. Improved logging.
Updated PretransformVertices. The step works now (and supports line and point meshes). Important: The position of the step in the pipeline has changed. No unit test yet.
Minor fixes to SortByPType. Added a config option that allows users to specify which primitive types they don't need.
Added WIP version of an Irrlicht Scene Loader (.irr).
Added a small helper class ("BatchLoader") to make it easy for loaders to load subsequent meshes from external files (needed for irr and lws).
Added test models for IRR. Added dwarf.x from the Irrlicht repository (readme included) to the test X files.
[Current TODO: Fix bugs in: AC, 3DS, LWO. Finish MDR and OG. Implement: IRR, LWS. Write some more ut's ... ]
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@197 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Added irrmesh (Irrlicht Mesh Format) loader to Assimp. Works quite stable, but no lightmapping support yet.
Removed tinyxml, replaced it with irrxml instead. Added an IOStreamToIrrXML wrapper.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@194 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Moved the code to find degenerated primitives to a separate step that is not anymore active by default.
The FindInvalidData-Step isn't active by default now. It hast a flag and must be explicitly requested.
Added line and point handling code to the CalcTangentsStep - not yet tested.
Added support for the Sense 8 (WorldToolKit) NFF file format. The format uses the same file extension as the "Neutral File Format" (and is implemented in the same loader). Seems to work well, added test files for it.
Added itoa10 function - so we have itoa on all platforms.
Small optimizations in the SortByPType step.
Fixed the material validation: textured meshes without uv coords cause a warning now.
Fixed a minor isses with the OFF loader.
Added empty unit tests for the new steps - to be filled in the next days.
Added SceneCombiner.cpp. It contains utilities to join meshes and scenes. The latter will be needed by the LWS loader (LWS files contain references to external LWO files and the LWO loader is already to complicated that it would make sense to add an additional code path to it). Mesh joining is needed by some pp steps, but the code has not yet been moved to its new location.
Added WIP light & camera support to the ASE loader. Works for the moment, but there's much missing. ASE parser refactored, the code is still quite long but at least cleaner. Fixed a bug that caused ASE to import invalid texture coordinates.
Makefiles and VC8 solution are up-to-date. The rest isn't.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@192 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Added some more essential includes to AssimpPCH.hAdded support for line and point meshes to most steps - I did nto yet adapt all unit tests, so meshes with mixed primitive types are not absolutely safe at the moment.
Added camera and light support to the PretransformVert step. Fixed some small inaccuracies and fixed a bug reported by Mark Sibly causing all transformations to be invalid. However the step is nto yet completely correct, there are still some small artifacts.
Updated light and camera data structures, added temporary validation code for the
Renamed AI_SCENE_FLAGS_ANIM_SKELETON_ONLY to a more generic AI_SCENE_FLAGS_INCOMPLETE flag.
Fixed bug in the OFF loader causing meshes with polygons to crash
Added line support to the DXF loader - seems to fail for the moment cause of SortByPType.
Added support for lights and cameras to NFF, implemented another NFF format subtype (file starts with 'nff'). Implemented NFF 'tpp' chunk and a corresponding texture extension.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@185 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
