MetaBall.cpp File Reference

A MetaObject exerts a positive or negative 'charge' in a scalar field, whose isocontours (level sets) define blobby surfaces with different threshold values corresponding to the contour level. MetaObjects positively or negatively affect their neighboring MetaObjects depending on their 'strength' and 'negative' attributes. A MetaBall exerts a non-zero charge (aka influence) over a spherical region emanating from a single point, 'position', out to a maximum distance of 'radius'. More...

MetaObjects positively or negatively affect their neighboring MetaObjects depending on their 'strength' and 'negative' attributes.
