PyAssimp: Python bindings for libassimp ======================================= 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. .. figure:: 3d_viewer_screenshot.png :alt: Screenshot Screenshot To use it, from within ``/port/PyAssimp``: :: $ cd scripts $ python ./3D-viewer 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 ...): .. code:: python from pyassimp import load with load('hello.3ds') as scene: assert len(scene.meshes) mesh = scene.meshes[0] assert len(mesh.vertices) print(mesh.vertices[0]) Another example to list the 'top nodes' in a scene: .. code:: python from pyassimp import load with load('hello.3ds') as scene: for c in scene.rootnode.children: print(str(c)) 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.
