 Tiny but poweful single file wavefront obj loader written in C++. No dependency except for C++ STL. It can parse 10M over polygons with moderate memory and time.

 What's new
 ----------
 
+* Jun 23, 2015 : Various fixes and added more projects using tinyobjloader. Thanks many contributors!
+* Mar 03, 2015 : Replace atof() with hand-written parser for robust reading of numeric value. Thanks skurmedel!
+* Feb 06, 2015 : Fix parsing multi-material object
 * Sep 14, 2014 : Add support for multi-material per object/group. Thanks Mykhailo!
 * Mar 17, 2014 : Fixed trim newline bugs. Thanks ardneran!
 * Apr 29, 2014 : Add API to read .obj from std::istream. Good for reading compressed .obj or connecting to procedural primitive generator. Thanks burnse!
