Detailed Description

This implicit function mollifies on implicit function using another implicit function (e.g., "GaussianSphereIF"). Basically, the IF being mollified is sampled in a small (specified) neighborhood of a point and convolved with the mollifying function in this neighborhood.

Constructor & Destructor Documentation

MollifyIF::MollifyIF ( const BaseIF a_impFunc,
