-PyAssimp Readme
-===============
-
-A simple Python wrapper for Assimp using `ctypes` to access the library.
-Requires Python >= 2.6.
-
-Python 3 support is mostly here, but not well tested.
-
-Note that pyassimp is not complete. Many ASSIMP features are missing.
-
-USAGE
------
-
-### Complete example: 3D viewer
-
-`pyassimp` comes with a simple 3D viewer that shows how to load and display a 3D
-model using a shader-based OpenGL pipeline.
-
-![Screenshot](3d_viewer_screenshot.png)
-
-To use it, from within `/port/PyAssimp`:
-
-```
-$ cd scripts
-$ python ./3D-viewer <path to your model>
-```
-
-You can use this code as starting point in your applications.
-
-### Writing your own code
-
-To get started with `pyassimp`, examine the simpler `sample.py` script in `scripts/`,
-which illustrates the basic usage. All Assimp data structures are wrapped using
-`ctypes`. All the data+length fields in Assimp's data structures (such as
-`aiMesh::mNumVertices`, `aiMesh::mVertices`) are replaced by simple python
-lists, so you can call `len()` on them to get their respective size and access
-members using `[]`.
-
-For example, to load a file named `hello.3ds` and print the first
-vertex of the first mesh, you would do (proper error handling
-substituted by assertions ...):
-
-```python
-
-from pyassimp import *
-scene = load('hello.3ds')
-
-assert len(scene.meshes)
-mesh = scene.meshes[0]
-
-assert len(mesh.vertices)
-print(mesh.vertices[0])
-
-# don't forget this one, or you will leak!
-release(scene)
-
-```
-
-Another example to list the 'top nodes' in a
-scene:
-
-```python
-
-from pyassimp import *
-scene = load('hello.3ds')
-
-for c in scene.rootnode.children:
-    print(str(c))
-
-release(scene)
-
-```
-
-INSTALL
--------
-
-Install `pyassimp` by running:
-
-```
-$ python setup.py install
-```
-
-PyAssimp requires a assimp dynamic library (`DLL` on windows,
-`.so` on linux, `.dynlib` on macOS) in order to work. The default search directories 
-are:
-
-- the current directory
-- on linux additionally: `/usr/lib`, `/usr/local/lib`,
-  `/usr/lib/x86_64-linux-gnu`
-
-To build that library, refer to the Assimp master `INSTALL`
-instructions. To look in more places, edit `./pyassimp/helper.py`.
-There's an `additional_dirs` list waiting for your entries.
