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.
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 [].
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[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:
from pyassimp import *
scene = load('hello.3ds')
for c in scene.rootnode.children:
print(str(c))
release(scene)
Install 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
are:
- the current directory
- on linux additionally:
/usr/lib
and/usr/local/lib
To build that library, refer to the Assimp master INSTALL
instructions. To look in more places, edit ./pyassimp/helper.py
.
