Interactive Modeling of Support-free Shapes for Fabrication

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 ...

Warp-based helical implicit primitives

Implicit modeling with skeleton-based primitives has been limited up to now to planar skeletons elements, since no closed-form solution was found for convolution along more complex curves. We show that warping techniques can be adapted to efficiently generate convolution-like implicit primitives of varying radius along helices, a useful 3D skeleton found in a number of natural shapes. Depending...

Planning Reconstruction for Facial Asymmetry

This paper describes the use of 3D shape modeling to plan reconstructive facial surgery for children born with facial asymmetry. The study used 3D images synthesized from high resolution CT scans. The images were manipulated using geometric morphometrics and the principal components of variation were derived. The software developed allows the user to either reconstruct how the whole face would ...
