I just can't get this to work. Accuracy, method and max_gradient (over 2000)
have no effect at all. The artifact stays there.
The right half of the front-side of the box is shadowed. It depends on
the location of the camera (eg. if the camera is moved a bit to the right, the
shadowed area moves as well).
Another interesting effect happens when you uncomment the last light_source
in the example scene. Since it's inside the isosurface, it shouldn't illuminate
anything. However, it not only illuminates the isosurface itself but also
the floor.
Any explanation / fix suggestion?
