Building and Animating User-Specific Volumetric Face Rigs

Ladislav Kavan, Mark Pauly, Alexandru Eugen Ichim, Merlin Eléazar Nimier-David

Currently, the two main approaches to realistic facial animation are 1) blendshape models and 2) physics-based simulation. Blendshapes are fast and directly controllable, but it is not easy to incorporate features such as dynamics, collision resolution, or ...

Exploratory Topology Modelling of Form-Active Hybrid Structures

Mark Pauly, Anders Holden Deleuran

The development of novel form-active hybrid structures (FAHS) is impeded by a lack of modelling tools that allow for exploratory topology modelling of shaped assemblies. We present a flexible and real-time computational design modelling pipeline developed ...

Beyond Developable: Computational Design and Fabrication with Auxetic Materials

Sofien Bouaziz, Mark Pauly, Bailin Deng, Mina Konakovic Lukovic

We present a computational method for interactive 3D design and rationalization of surfaces via auxetic materials, i.e., flat flexible material that can stretch uniformly up to a certain extent. A key motivation for studying such material is that one can a ...

Sphere-Meshes for Real-Time Hand Modeling and Tracking

Mark Pauly, Anastasia Tkach, Andrea Tagliasacchi

Modern systems for real-time hand tracking rely on a combination of discriminative and generative approaches to robustly recover hand poses. Generative approaches require the specification of a geometric model. In this paper, we propose a the use of sphere ...

Discovering Structured Variations via Coupled Template Matching

Duygu Ceylan, Mark Pauly, Ngoc Minh Dang, Boris Neubert

Understanding patterns of variation from raw measurement data remains a central goal of shape analysis. This understanding reveals which elements are exactly repeated, or how elements can be derived as structured variations from a common base element. We i ...

ShapeOp - A Robust and Extensible Geometric Modelling Paradigm

Sofien Bouaziz, Mark Pauly, Mario Moacir Deuss, Bailin Deng, Anders Holden Deleuran

We present ShapeOp, a robust and extensible geometric modelling paradigm. ShapeOp builds on top of the state-of-the-art physics solver (Bouaziz et al. in ACM Trans Graph 33:154:1–154:11, 2014). We discuss the main theoretical advantages of the underlying s ...

Interactive Design of Probability Density Functions for Shape Grammars

Duygu Ceylan, Mark Pauly, Stefan Lienhard, Boris Neubert

A shape grammar defines a procedural shape space containing a variety of models of the same class, e.g. buildings, trees, furniture, airplanes, bikes, etc. We present a framework that enables a user to interactively design a probability density function (p ...

Robust Articulated-ICP for Real-Time Hand Tracking

Sofien Bouaziz, Mark Pauly, Anastasia Tkach, Andrea Tagliasacchi

We present a robust method for capturing articulated hand motions in realtime using a single depth camera. Our system is based on a realtime registration process that accurately reconstructs hand poses by fitting a 3D articulated hand model to depth images ...

Dynamic 3D Avatar Creation from Hand-held Video Input

Sofien Bouaziz, Mark Pauly, Alexandru Eugen Ichim

We present a complete pipeline for creating fully rigged, personalized 3D facial avatars from hand-held video. Our system faithfully recovers facial expression dynamics of the user by adapting a blendshape template to an image sequence of recorded expressi ...

Self Tuning Texture Optimization

Alexandre Kaspar, Mark Pauly, Boris Neubert

The goal of example-based texture synthesis methods is to generate arbitrarily large textures from limited exemplars in order to fit the exact dimensions and resolution required for a specific modeling task. The challenge is to faithfully capture all of th ...

Interactive design exploration for constrained meshes

Sofien Bouaziz, Alexandre Kaspar, Yuliy Gennadievich Schwartzburg, Mark Pauly, Mario Moacir Deuss, Bailin Deng

In architectural design, surface shapes are commonly subject to geometric constraints imposed by material, fabrication or assembly. Rationalization algorithms can convert a freeform design into a form feasible for production, but often require design modif ...

A hydrodynamically optimized nano-electrospray ionization source and vacuum interface

Klaus Kern, Stephan Rauschenbach, Mark Pauly, Gordon Rinke

The coupling of atmospheric pressure ionization (API) sources like electrospray ionization (ESI) to vacuum based applications like mass spectrometry (MS) or ion beam deposition (IBD) is done by differential pumping, starting with a capillary or pinhole inl ...

Method of producing a reflective or refractive surface

Mark Pauly

A method and apparatus for producing a reflective or refractive surface that reflects or refracts light shined thereon and reproduces on a screen a desired greyscale intensity image on which the reflective or refractive surface is based and a corresponding ...

Projective Dynamics: Fusing Constraint Projections for Fast Simulation

Ladislav Kavan, Sofien Bouaziz, Mark Pauly

We present a new method for implicit time integration of physical systems. Our approach builds a bridge between nodal Finite Element methods and Position Based Dynamics, leading to a simple, efficient, robust, yet accurate solver that supports many differe ...

SAFE: Structure-aware Facade Editing

Duygu Ceylan, Mark Pauly, Ngoc Minh Dang, Boris Neubert

Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often there are numerous plausible editing ...

Assembling Self-Supporting Structures

Mark Pauly, Mario Moacir Deuss, Yang Liu

Self-supporting structures are prominent in historical and contemporary architecture due to advantageous structural properties and efficient use of material. Computer graphics research has recently contributed new design tools that allow creating and inter ...

Coupled Structure-from-Motion and 3D Symmetry Detection for Urban Facades

Duygu Ceylan, Mark Pauly

Repeated structures are ubiquitous in urban facades. Such repetitions lead to ambiguity in establishing correspondences across sets of unordered images. A decoupled structure-from-motion reconstruction followed by symmetry detection often produces errors: ...

Wire Mesh Design

Mark Pauly, Bailin Deng, Akash Garg

We present a computational approach for designing wire meshes, i.e., freeform surfaces composed of woven wires arranged in a regular grid. To facilitate shape exploration, we map material properties of wire meshes to the geometric model of Chebyshev nets. ...

High-contrast Computational Caustic Design

Romain Pierre Testuz, Yuliy Gennadievich Schwartzburg, Mark Pauly, Andrea Tagliasacchi

We present a new algorithm for computational caustic design. Our algorithm solves for the shape of a transparent object such that the refracted light paints a desired caustic image on a receiver screen. We introduce an optimal transport formulation to esta ...
