Detailed Description

FBMatrix class.

Four x Four (double) Matrix.

This class creates a list like object, which can be modified using the list protocol method. But unlike lists, its length is fixed: it always contain 16 floating point values. Thus it does not support the any list methods that would affect its length. The values within can be changed, usually via the bracket operator.

# Supported list protocol methods:
mat = FBMatrix()
len(mat)
print mat[13]
mat[12] = 1.0

Warning

The implementation of this 4x4 matrix uses a simple list of 16 elements, not a list of 4 vectors of 4 elements.*

Slicing is not supported by this object.

See samples: Matrix.py, FreezeLocalRotation.py.
