Inverse Geometric Locomotion

Numerous tasks in robotics and character animation involve solving combinations of inverse kinematics and motion planning problems that require the precise design of pose sequences to achieve desired motion objectives. Accounting for the complex interplay ...

C-Tubes: Design and Optimization of Tubular Structures Composed of Developable Strips

Mark Pauly, Michele Vidulis, Florin Isvoranu, Quentin Christian Becker

We introduce C-tubes, 3D tubular structures composed of developable surface strips. C-tubes can be understood as a generalization of Monge surfaces---a special class of sweep surfaces---towards the recently introduced cone-nets. This observation allows fo ...

Computational Design of Deployable Gridshells with Curved Elastic Beams

Quentin Christian Becker

Deployable gridshells are lightweight structures made of interconnected elastic beams. They can be actuated from a compact state to a freeform and volume-enclosing deployed shape. This thesis introduces C-shells, a novel class of deployable gridshells, whi ...

Interactive Design of C-shells Using Reduced Parametric Families

Mark Pauly, Quentin Christian Becker, Seiichi Eduardo Suzuki Erazo

Elastic gridshells are a class of planar-to-3D linkages typically composed of straight flexible beams connected via rigid rotational joints. The integration of planar curved flexible beams into these linkages significantly broadens their design space, allo ...

Computational Design of a Kit of Parts for Bending Active Structures

Mark Pauly, Uday Kusupati, Quentin Christian Becker, Seiichi Eduardo Suzuki Erazo

Bending-active structures are composed of elastic elements that deform to achieve a desired target shape. To support effective design, inverse algorithms have been proposed that optimize the geometry of each element specifically for each design. This makes ...

C-shells: Deployable Gridshells with Curved Beams

Mark Pauly, Francis Julian Panetta, Yingying Ren, Quentin Christian Becker, Davide Pellis, Seiichi Eduardo Suzuki Erazo

We introduce a computational pipeline for simulating and designing C-shells, a new class of planar-to-spatial deployable linkage structures. A C-shell is composed of curved flexible beams connected at rotational joints that can be assembled in a stress-fre ...

On Linear Interpolation in the Latent Space of Deep Generative Models

Quentin Christian Becker, Mike Yan Michelis

The underlying geometrical structure of the latent space in deep generative models is in most cases not Euclidean, which may lead to biases when comparing interpolation capabilities of two models. Smoothness and plausibility of linear interpolations in lat ...
