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. In particular, only loading of models is currently supported (no export).
To get started with pyAssimp, examine the
sample.py script in
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::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 ...):
from pyassimp import * scene = load('hello.3ds') assert len(scene.meshes) mesh = scene.meshes assert len(mesh.vertices) print(mesh.vertices) # don't forget this one, or you will leak! release(scene)
Another example to list the 'top nodes' in a scene:
from pyassimp import * scene = load('hello.3ds') for c in scene.rootnode.children: print(str(c)) release(scene)
pyassimp by running:
python setup.py install
PyAssimp requires a assimp dynamic library (
DLL on windows,
.so on linux :-) in order to work. The default search directories
- the current directory
- on linux additionally:
To build that library, refer to the Assimp master INSTALL
instructions. To look in more places, edit
additional_dirs list waiting for your entries.
