Draws domain edges on an existing volume rendering.

Draws a white wireframe on the domain edges.

Parameters:

Parameters:	im: Numpy ndarray : Existing image that has the same resolution as the Camera, which will be painted by grid lines. alpha : float, optional The alpha value for the wireframe being drawn. Used to control how bright the lines are with respect to the image. Default : 0.3
Returns:	nim: Numpy ndarray : A new image with the domain lines drawn

im: Numpy ndarray :

Existing image that has the same resolution as the Camera, which will be painted by grid lines.

alpha : float, optional

Examples

>>> im = cam.snapshot() 
>>> nim = cam.draw_domain(im)
>>> write_bitmap(nim, 'render_with_domain_boundary.png')
