Spectral Rendering with the Bounded MESE and sRGB Data
(The Eurographics Association, 2019)
In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ...
Real-Time Sound Synthesis for Paper Material Based on Geometric Analysis
(The Eurographics Association, 2016)
In this article, we present the first method to generate plausible sounds while animating crumpling virtual paper in real time. Our method handles shape-dependent friction and crumpling sounds which typically occur when ...
Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...
Geometric Accuracy Analysis of Stationary BTF Gonioreflectometers
(The Eurographics Association, 2015)
The accurate BTF data representation requires specialized measurement gantries, some of them designed as gonireflectometers. These consist of an illumination source and a camera mounted on two robotic arms, one degree of ...
LandSketch: A First Person Point-of-View Example-Based Terrain Modeling Approach
(ACM, 2013)
We present an intuitive interface for easy modeling of terrains, compatible with example-based synthesis approach. The interface consists on a picture's canvas-like screen, where the user sketches silhouettes of mountains, ...
Accurate Surface Embedding for Higher Order Finite Elements
(ACM SIGGRAPH / Eurographics Association, 2013)
In this paper we present a novel approach to efficiently simulate the deformation of highly detailed meshes using higher order finite elements (FE). An efficient algorithm based on non-linear optimization is proposed in ...
SymPan: 3D Model Pose Normalization via Panoramic Views and Reflective Symmetry
(The Eurographics Association, 2013)
A novel pose normalization method, based on panoramic views and reflective symmetry, is presented. Initially, the surface of a 3D model is projected onto the lateral surface of a circumscribed cylinder, aligned with the ...
Efficient Simulation of Secondary Motion in Rig-Space
(ACM SIGGRAPH / Eurographics Association, 2013)
We present an efficient method for augmenting keyframed character animations with physically-simulated secondary motion. Our method achieves a performance improvement of one to two orders of magnitude over previous work ...
Hierarchical hp-Adaptive Signed Distance Fields
(The Eurographics Association, 2016)
In this paper we propose a novel method to construct hierarchical hp-adaptive Signed Distance Fields (SDFs). We discretize the signed distance function of an input mesh using piecewise polynomials on an axis-aligned ...
Stylistic Patterns for Generating Cinematographic Sequences
(The Eurographics Association, 2015)
For film editors, the decision of how to compose and sequence camera framings is a question pertaining to a number of elements involving the semantics of shots, framings, story context, consistency of style, and artistic ...
