VXLSE's auto-normals do pretty well when there are small features, or face transitions of 1-2 pixels, but not when the transition is over 3+ pixels.

Since computation power is relatively free, can we add another auto-normals option based on whichever makes most sense, but biases gradual transitions across 5-7 or so pixels on a layer (perhaps allow us to choose threshold and target smoothness).

Then repeat that process once for each axis. If we could even choose which of the 3 axes to smooth this way, we could specify the slices to be from the TOP for a large vessel, since we would have no need to smooth from the SIDE, and we could choose a more aggressive smoother from FRONT. I think this could go a long way to bridging the quality gap to converted 3d models.

I think it makes the most sense to do the calculations as individual layers, smoothing the direction of normals to prevent jaggies in arcs.

The settings I envision are much like the convo we had ages ago about vxl->3d rendering, using a threshold to determine what counts as a feature vs a slope. Either a threshold of dots to include, or a threshold for transition depth...

Thoughts?

You need the knowledge of context to do it in a proper way. This is part of my PhD thesis and I'll still take a long time to finish it.

Well this is why I suggest the threshold setting for the user to play with, and using it on a single layer. Then the context is whatever the user decides works best.
