# tinyobjloader, Wavefront .obj loader
`tinyobjloader` is a python wrapper for C++ wavefront .obj loader.
`tinyobjloader` is rather fast and feature rich than other pure python version of .obj loader.
## Install
You can install `tinyobjloader` with pip.
```
$ pip install tinyobjloader
```
## Quick tutorial
```py
import sys
import tinyobjloader
# Create reader.
reader = tinyobjloader.ObjReader()
filename = "cornellbox.obj"
# Load .obj(and .mtl) using default configuration
ret = reader.ParseFromFile(filename)
if ret == False:
print("Warn:", reader.Warning())
pint("Err:", reader.Error())
print("Failed to load : ", filename)
sys.exit(-1)
if reader.Warning():
print("Warn:", reader.Warning())
attrib = reader.GetAttrib()
print("attrib.vertices = ", len(attrib.vertices))
print("attrib.normals = ", len(attrib.normals))
print("attrib.texcoords = ", len(attrib.texcoords))
materials = reader.GetMaterials()
print("Num materials: ", len(materials))
for m in materials:
print(m.name)
print(m.diffuse)
shapes = reader.GetShapes()
print("Num shapes: ", len(shapes))
for shape in shapes:
print(shape.name)
print("num_indices = {}".format(len(shape.mesh.indices)))
```
