快速的 C OBJ 解析器
Because the world needs another OBJ loader. Single header library, should compile without warnings in both C89 or C++. Much faster (5-10x) than other libraries tested.
To use:
fastObjMesh* mesh = fast_obj_read("path/to/objfile.obj");
...do stuff with mesh...
fast_obj_destroy(mesh);
Note that valid indices in the fastObjMesh::indices array start from 1. A dummy position, normal and
texture coordinate are added to the corresponding fastObjMesh arrays at element 0 and then an index
of 0 is used to indicate that attribute is not present at the vertex. This means that users can avoid
the need to test for non-present data if required as the vertices will still reference a valid entry in
the mesh arrays.
A simple test app is provided to compare speed against tinyobjloader and check output matches.
Version 1.3 makes a small change to the API. Textures are now stored in a separate array on the
fastObjMesh structure, and are referenced by index from materials, instead of being referenced
by the material directly.
