Smoothing Surfaces #682

Open ajweis opened 4 years ago

Is your feature request related to a problem? Please describe. When modeling an aneurysm, it seems as though SimVascular over smooths the surface, but there is no way to correct or this over smoothing.

Describe the solution you'd like A parameter to control the smoothing factor of the surface would be helpful.

Describe alternatives you've considered I've tried to correct for this issue by adjusting the other parameters that are available for modeling (thresholds, propagation scaling, advection scaling, curvature scaling, iterations), but it doesn't allow me to produce an accurate model of the vessel and the aneurysm.

@ajweis Sorry, I don't understand the context. How are you modeling the aneurysm?

ajweis commented 4 years ago

I'm sorry, I should have said segmenting. I used colliding fronts to segment a region including the brain aneurysm. When I ran colliding fronts, it over-smoothed the surface and I could not find a combination of parameters that corrected for the smoothing.

I'm not too familiar with colliding fronts, let me experiment with it a bit.
