PyAssimp Readme
|
|
===============
|
|
|
|
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).
|
|
|
|
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 [].
|
|
|
|
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 ...):
|
|
|
|
```python
|
|
|
|
from pyassimp.core 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:
|
|
|
|
```python
|
|
|
|
from pyassimp.core import *
|
|
scene = load('hello.3ds')
|
|
|
|
for c in scene.rootnode.children:
|
|
print(str(c))
|
|
|
|
release(scene)
|
|
|
|
```
|
|
|
|
INSTALL
|
|
-------
|
|
|
|
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`.
|
|
There's an `additional_dirs` list waiting for your entries.
