1db46c242f
Added AC-loader, WIP version. PLY loader is now able to load models from blender, test model added. Refactoring. Added FindInvalidData step. Added support for precompiled headers, the release builds in VC8 are configued to use PCH now. Added separate makefile for mingw, no -FPic warning anymore, -clear works now. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@176 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
