/** @file Implementation of the CPP-API class #Importer */
#include "AssimpPCH.h"
General - Added format auto-detection to most loaders - Simplified BaseImporter::CanRead() with some utility methods - improved fast_atof -> no overruns anymore. Fuck you, irrlicht. - added assimp_cmd tool to allow command line model processing. Mainly adebugging tool for internal purposes, but others might find it useful, too. - vc8/vc9: revision number is now written to DLL version header - mkutil: some batch scripts to simplify tagging & building of release versions - some API cleanup - fixing some doxygen markup (+now explicit use of @file <filename>) - Icon for assimp_view and assimp_cmd 3DS - Normal vectors are not anymore inverted in some cases - Improved pivot handling - Improved handling of x-flipped meshes Collada - fixed a minor bug (visual_scene element) LWS - WIP implementation. No animations yet, some bugs and crashes. - Animation system remains disabled, WIP code - many test files for LWS, but most of them test the anim support, which is, read above, currently disabled. STL - fixing a log warning which appears for every model - added binary&ascii test spider, exported from truespace MD3 - Cleaning up output tags for automatically joined player models. IRR - Fixing coordinate system issues. - Instance handling improved. - Some of the reported crashes not yet fixed. PretransformVertices - Numerous performance improvements. - Added config option to preserve the hierarchy during the step. RemoveRedundantMaterials - Added config option to specify a list of materials which are kept in every case. UNREAL - Added support for the old unreal data format (*.a,*.d,*.uc) - tested only with exports from Milkshape - more Unreal stuff to come soon git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@356 67173fc5-114c-0410-ac8e-9d2fd5bffc1f

Fixed some minor issues in the AC loader. However, it still crashes with large and complicated models. Line handling is complete. 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

Fixed some minor issues in the AC loader. However, it still crashes with large and complicated models. Line handling is complete. 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

General - Added format auto-detection to most loaders - Simplified BaseImporter::CanRead() with some utility methods - improved fast_atof -> no overruns anymore. Fuck you, irrlicht. - added assimp_cmd tool to allow command line model processing. Mainly adebugging tool for internal purposes, but others might find it useful, too. - vc8/vc9: revision number is now written to DLL version header - mkutil: some batch scripts to simplify tagging & building of release versions - some API cleanup - fixing some doxygen markup (+now explicit use of @file <filename>) - Icon for assimp_view and assimp_cmd 3DS - Normal vectors are not anymore inverted in some cases - Improved pivot handling - Improved handling of x-flipped meshes Collada - fixed a minor bug (visual_scene element) LWS - WIP implementation. No animations yet, some bugs and crashes. - Animation system remains disabled, WIP code - many test files for LWS, but most of them test the anim support, which is, read above, currently disabled. STL - fixing a log warning which appears for every model - added binary&ascii test spider, exported from truespace MD3 - Cleaning up output tags for automatically joined player models. IRR - Fixing coordinate system issues. - Instance handling improved. - Some of the reported crashes not yet fixed. PretransformVertices - Numerous performance improvements. - Added config option to preserve the hierarchy during the step. RemoveRedundantMaterials - Added config option to specify a list of materials which are kept in every case.
