Note that when `triangulate` flas is true in `tinyobj::LoadObj()` argument, `num_face_vertices` are all filled with 3(triangle). Note that when `triangulate` flas is true in `tinyobj::LoadObj()` argument, `num_face_vertices` are all filled with 3(triangle).
### float data type
TinyObjLoader now use `real_t` for floating point data type.
Default is `float(32bit)`.
You can enable `double(64bit)` precision by using `TINYOBJLOADER_USE_DOUBLE` define.
