nipy.labs.viz_tools.maps_3d.affine_img_src(data, affine, scale=1, name='AffineImage', reverse_x=False)

Make a Mayavi source defined by a 3D array and an affine, for which the voxel of the 3D array are mapped by the affine.

data: 3D ndarray

The data arrays

affine: (4 x 4) ndarray

The (4 x 4) affine matrix relating voxels to world coordinates.

scale: float, optional

An optional addition scaling factor.

name: string, optional

The name of the Mayavi source created.

reverse_x: boolean, optional

Reverse the x (lateral) axis. Useful to compared with images in radiologic convention.


The affine should be diagonal.
