Loading A Collada Document

Collada documents can be loaded with the Collada class:

mesh = Collada('file.dae')

Zip archives are also supported. The archive will be searched for a dae file.

The constructor can also accept a file-like object:

f = open('file.dae')
mesh = Collada(f)

Note that this will also work with the StringIO module. When loading from non-file sources, the aux_file_loader parameter can be passed to the constructor. This is useful if loading from an unusual source, like a database:

dae_file = open('file.dae')
dae_data = dae_file.read()
texture_file = open('texture.jpg')
texture_data = texture_file.read()

def my_aux_loader(filename):
    if filename == 'texture.jpg':
        return texture_data
    return None

mesh = Collada(StringIO(dae_data), aux_file_loader=my_aux_loader)

When using the Collada object (see Collada Object Structure), if you try and read a texture, the my_aux_loader function will be invoked.

Loading a collada document can result in an exception being thrown. For a list of possible exceptions, see Exceptions. Sometimes, you may want to ignore some exceptions and let the loader try to continue loading the file. For example, the following will ignore errors about broken references and features that pycollada doesn’t support:

mesh = Collada('file.dae', ignore=[DaeUnsupportedError, DaeBrokenRefError])

If any errors occurred during the load, you can find them in Collada.errors.
