PyAssimp Readme
|
|
---------------
|
|
|
|
|
|
-- a simple Python wrapper for Assimp using ctypes to access
|
|
the library. Tested for Python 2.6. Known not to work with
|
|
Python 2.4.
|
|
|
|
|
|
Note that pyassimp is by no means considered mature. It works,
|
|
but it is far away from wrapping Assimp perfectly.
|
|
|
|
|
|
USAGE
|
|
=====
|
|
|
|
To get started with pyAssimp, examine the sample.py script, 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 pyassimp, errors
|
|
>
|
|
> try:
|
|
> scene = pyassimp.load('hello.3ds')
|
|
> except AssimpError, msg:
|
|
> print(msg)
|
|
> return
|
|
|
|
> 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!
|
|
> pyassimp.release(scene)
|
|
|
|
|
|
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/local/lib
|
|
|
|
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.
