Interactive Modeling of Support-free Shapes for Fabrication
Résumé
We introduce an interactive sculpting approach that enables modeling of support-free objects: objects which do not require any
support structures during 3D printing. We propose three operators – trim, preserve, grow – to maintain the support-free property
during interactive modeling. These operators let us define brushes that perform either in an unconstrained manner (adapting
the shape to the brush effect), or selectively discard changes inside the brush volume. Our technique can be applied to many
modeling operations and we demonstrate it on brushes for adding or removing matter. We describe an efficient implementation of
a voxel-based modeling tool that produces only support-free shapes, and show example shapes modeled within minutes
