Recent Projects

SIGGRAPH ASIA 2016 FlexMolds: Automatic Design of Flexible Shells for Molding

We present FlexMolds, a novel computational approach to automatically design flexible, reusable molds that, once 3D printed, allow us to physically fabricate, by means of liquid casting, multiple copies of complex shapes with rich surface details and complex topology. The approach to design such flexible molds is based on a greedy bottom-up search of possible cuts over an object, evaluating for each possible cut the feasibility of the resulting mold.

PACIFIC GRAPHICS 2016 Tracing Field-Coherent Quad Layouts

Given a cross field over a triangulated surface we present a practical and robust method to compute a field aligned coarse quad layout over the surface. The method works directly on a triangle mesh without requiring any parametrization and it is based on a new technique for tracing field-coherent geodesic paths directly on a triangle mesh.

SIGGRAPH 2015 Elastic Textures for Additive Fabrication

We introduce elastic textures: a set of parametric, tileable, printable, cubic patterns achieving a broad range of elastic material properties: the softest pattern is over a thousand times softer than the stiffest, and the Poisson ratios range from below zero to nearly 0.5. Using a combinatorial search over topologies followed by shape optimization, we explore a wide space of wireframe-like, symmetric 3D patterns to obtain a small family.

SIGGRAPH 2015 Data-Driven Interactive Quadrangulation 

We propose an interactive quadrangulation method based on a large collection of patterns that are learned from models manually designed by artists. The patterns are distilled into compact quadrangulation rules and stored in a database. At run-time, the user draws strokes to define patches and desired edge flows, and the system queries the database to extract fitting patterns to tessellate the sketches' interiors...

EUROGRAPHICS 2015 Statics Aware Grid Shells

We introduce a framework for the generation of polygonal grid-shell architectural structures, whose topology is designed in order to excel in static performances....

ACM SIGGRAPH 2014 Robust Field-aligned Global Parametrization

We present a robust method for computing locally bijective global parametrizations aligned with a given cross-field. The singulari- ties of the parametrization in general agree with singularities of the field, except in a small number of cases when several additional cones need to be added in a controlled way.

ACM TOG (To be presented at SigAsia 2014)Field-Aligned Mesh Joinery

Mesh joinery is an innovative method to produce illustrative shape approxi- mations suitable for fabrication. Mesh joinery is capable of producing com- plex fabricable structures in an efficient and visually pleasing manner. We represent an input geometry as a set of planar pieces arranged to compose a rigid structure, by exploiting an efficient slit mechanism. Since slices are planar, to fabricate them a standard 2D cutting system is enough. We automatically arrange slices according to a smooth cross field defined over the surface. Cross fields allow representing global features that char- acterize the appearance of the shape. Slice placement conforms to specific manufacturing constraints.
