Hello  Erik, other  mentors and developers .

 I would like to have your views and clarifications as regards
implementing options for the heart primitive .

I am having some issues determining the exact key properties of the
heart to serve for the internal representation in the database. (This
will help for the ID_HRT in rtgeom.h)
I have been looking at the metaball primitive and the Blobby method
which was used to implement it. Since  2 spheres to implement the
metaball. I was thinking of using 2 spheres and an elliptical parabola
(epa)  to implement the heart. The spheres will serve as the lobes of
the heart and the epa will be the bottom section.

Regards.
Izak.
