Thanks, Molly. I'm pretty happy with the results so far.
You bring up an interesting point, K1TesseraEna.
I'm not sure what the best terminology to use would be, but I'm open to suggestions. Here is the way options are now termed.
Slope OptionsFLATFrom left to right: Flat with no smoothing, Flat with smoothing, Flat with less depth.



I suppose this could be considered a Flat Slope or a Flat Bevel. In other words, it is not really a curved slope. Adjusting the smoothing parameter does round the sharp edges. I believe this type of bevel is sometimes referred to as chiseled. When I decrease the depth, it also decreases the reflectivity.
ROUND1From left to right: Round1 (Default Depth of 7), Round1 (Depth of 4), Round1 (Depth of 2).


ROUND2From left to right: Round2 (Default Depth of 20), Round2 (Depth of 7), Round2 (Depth of 4).



There are differences in the various types of slopes/bevels but I'm not sure how to describe those differences to avoid any confusion. The user is probably just going to have to test out these options interactively to see how their images react to changes in slope types and their corresponding parameters.
I'm certainly open to any ideas.
