Implicit Blending Revisited
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
Blending is both the strength and the weakness of functionally based implicit surfaces (such as F-reps or soft-objects). While it gives them the unique ability to smoothly merge into a single, arbitrary shape, it makes ...
Large Scale Terrain Generation from Tectonic Uplift and Fluvial Erosion
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in ...
Sketch-based Modeling
(The Eurographics Association, 2016)
Sketching is one of the most natural ways to exchange ideas. It has been used by human beings since prehistory. Research has shown that human beings have an inherent ability to understand sketches. This is why sketch-based ...
Generation of Folded Terrains from Simple Vector Maps
(The Eurographics Association, 2015)
While several terrain generation methods focused on plausible watersheds, the fact that most mountains should not be isolated but rather be part of wider scale mountain ranges was seldom considered. In this work, we present ...
Folded Paper Geometry from 2D Pattern and 3D Contour
(The Eurographics Association, 2011)
Folded paper exhibits very characteristic shapes, due to the presence of sharp folds and to exact isometry with a given planar pattern. Therefore, none of the physically-based simulators developed so far can handle paper-like ...
Mutable Elastic Models for Sculpting Structured Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we propose a new paradigm for free-form shape deformation. Standard deformable models minimize an energy measuring the distance to a single target shape. We propose a new, ''mutable'' elastic model. It ...
Geometric Details on Skeleton-based Implicit Surfaces
(The Eurographics Association, 2012)
We present a modeling technique to enhance implicit surfaces with procedural geometric details. The details are based on Gabor noise, which enables us to seamlessly handle anisotropy. The orientation of details can be ...
Replaceable Substructures for Efficient Part-Based Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
A popular mode of shape synthesis involves mixing and matching parts from different objects to form a coherent whole. The key challenge is to efficiently synthesize shape variations that are plausible, both locally and ...
Crowd Sculpting: A Space-time Sculpting Method for Populating Virtual Environments
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We introduce "Crowd Sculpting": a method to interactively design populated environments by using intuitive deformation gestures to drive both the spatial coverage and the temporal sequencing of a crowd motion. Our approach ...
