SNL: ZSweep does not handle concavities
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The ZSweep mapper is not correctly rendering when there is a concavity. I suspect the problem is that ZSweep is not properly recording when a face is external (or perhaps its direction) and is filling empty space between non adjacent cells as if there was a cell there.
The attached pvs file provides some data that demonstrates the problem. It is a Wavelet source with the higher values thresholded out. This leaves an empty space in the middle. When you turn on ZSweep, you see that in any place you have cells-space-cells, it looks really solid. It does not with either PT or Bunyk.
