Re: surface elements for transparent_solids.dem

[Daniel J S. <dan...@ie...>]

My previous mail has come through as of yet.  Anyway, I've found that the depth sort approach works a little better (at least for the Kuen surface) when using the average depth of corners as opposed to the max z value.

Well, a few of those flawed surfaces at the thin parts of the Kuen surface still seem odd to me.  The quadrangle on the back side *at the edge* seems to be ahead of the quandrangle on the front side *at the edge*.  But these two quadrangles share a couple points; so what I find hard to believe, looking at the Kuen surface from other angles, is that the two other points for the quadrangles average out so that the back quadrangle is more ahead.

But hold on, this may be for naught.  I may have an easier fix for this given the situation.  Give me a bit...
