USAGE
-----
To get started with pyAssimp, examine the `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 [].
### Complete example: 3D viewer
For example, to load a file named 'hello.3ds' and print the first
`pyassimp` comes with a simple 3D viewer that shows how to load and display a 3D
model using a shader-based OpenGL pipeline.

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.

substituted by assertions ...):

PyAssimp requires a assimp dynamic library (`DLL` on windows,
`.so` on linux :-) in order to work. The default search directories
`.so` on linux, `.dynlib` on macOS) in order to work. The default search directories
are:
- the current directory
- on linux additionally: `/usr/lib` and `/usr/local/lib`
- on linux additionally: `/usr/lib`, `/usr/local/lib`,
`/usr/lib/x86_64-linux-gnu`
To build that library, refer to the Assimp master INSTALL
To build that library, refer to the Assimp master `INSTALL`
instructions. To look in more places, edit `./pyassimp/helper.py`.
