Tiny but powerful 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.

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.
|
||||
|
||||
`tinyobjloader` is good for embedding .obj loader to your (global illumination) renderer ;-)
|
||||
|
||||
Notice!
|
||||
-------
|
||||
|
||||
`master` branch will be replaced with `develop` branch in the near future: https://github.com/syoyo/tinyobjloader/tree/develop
|
||||
`develop` branch has more better support and clean API interface for loading .obj and also it has optimized multi-threaded parser(probably 10x faster than `master`). If you are new to use `TinyObjLoader`, I highly recommend to use `develop` branch.
