Trying to learn how to use isosurfaces, I am playing with provided samples.
Specifically I am interested in seeing max_gradient estimation in action.
So I went to the isosurface in the crackle3.pov sample file, uncommented the
evaluate keyword and changed its parameters to 1, 10, 0.99 as suggested in
the manual. Also changed max_gradient to 5 as suggested. Then rendered it.
I am looking and looking in the Message window after rendering and I do not
see a warning about the max_gradient POV-Ray should have found for me to
copy and paste.
Is it called something else? Or am I doing something wrong? Or is this a
bug?
