	Either you gave a much too high value for max_gradient, or else it
varies greatly from point to point in your isosurface (I think eval
adjusts the max_gradient on a point by piont basis, whereas max_gradient
is necessarily global, therefore if there are only a couple of points
with a high gradient, eval should be faster than using this high value
for every point).
