Tiny but powerful single file wavefront obj loader written in C++03. No dependency except for C++ STL. It can parse over 10M polygons with moderate memory and time.

`tinyobjloader` is good for embedding .obj loader to your (global illumination) renderer ;-)

* 19 Feb, 2020 : The repository has been moved to https://github.com/tinyobjloader/tinyobjloader !

* 18 May, 2019 : Python binding!(See `python` folder. Also see https://pypi.org/project/tinyobjloader/)

* 14 Apr, 2019 : Bump version v2.0.0 rc0. New C++ API and python bindings!(1.x API still exists for backward compatibility)

* 20 Aug, 2016 : Bump version v1.0.0. New data structure and API!
