New EnSight 9.1 Feature: Smoother Isosurfaces

Darin at the “Viz Worth Watching” blog has posted a little tidbit about a new feature that’ll be available in the upcoming EnSight 9.1, coming directly from one of their engineers.

Some of you know I have been working on a little side feature for awhile now and finally got around to “finishing” it. There is a math function now called “SmoothMesh”. It takes 2D part(s) as input and computes a “smoother” mesh using a multi-pass spring model. The output of SmoothMesh is a vector variable that you apply to the original part as a displacement field. I have attached an image of a computed shock on the shroud dataset that I smoothed this way (upper viewport is the original, lower is the smoothed form). In the example, I used 100 passes with a weighting factor of 0.05.

Some more information is available on their site, but it seems to be a nice combination of mesh decimation with surface smoothing using an iterative approach.  Not terribly great for science, but great for those always-necessary marketing and presentation images.
