Modelling of Clouds from a Hemispherical Image
(The Eurographics Association, 2014)
This paper presents an image-based method for modelling clouds. Unlike previous image-based approaches, a hemispherical photograph is used as input, enabling to consider an entire sky instead of merely a portion. Our method ...
Continuous Collision Detection Between Points and Signed Distance Fields
(The Eurographics Association, 2014)
We present an algorithm for fast continuous collision detection between points and signed distance fields. Such robust queries are often needed in computer animation, haptics and virtual reality applications, but have so ...
Towards the Creation of Digital Stones from 2D Samples
(The Eurographics Association, 2014)
In order to decide which preservation strategies one should follow for Cultural Heritage objects made of stone, it is necessary to estimate the impact of different alternative strategies. A useful aid in such a process is ...
A p-Multigrid Algorithm using Cubic Finite Elements for Efficient Deformation Simulation
(The Eurographics Association, 2014)
We present a novel p-multigrid method for efficient simulation of co-rotational elasticity with higher-order finite elements. In contrast to other multigrid methods proposed for volumetric deformation, the resolution ...
Automatic Garment Modeling From Front And Back Images
(The Eurographics Association, 2014)
We present a system which can automatically generate a realistic garment model from two images of an existing garment. Without the requirement of tailoring expertise and tedious operation, our method takes the front and ...
A New Fast and Robust Collision Detection and Force Computation Algorithm Applied to the Physics Engine Bullet: Method, Integration, and Evaluation
(The Eurographics Association, 2014)
We present a collision detection and force computation algorithm based on the Voxelmap-Pointshell Algorithm which was integrated and evaluated in the physics engine Bullet. Our algorithm uses signed distance fields and ...
A Unified Topological-Physical Model for Adaptive Refinement
(The Eurographics Association, 2014)
In Computer Graphics, physically-based simulation of deformable objects is a current challenge, and many efficient models have been developed to reach real-time performance. However, these models are often limited when ...
Evaluating the Curvature Analysis as a Key Feature for the Semantic Description of Architectural Elements
(The Eurographics Association, 2014)
The recent developments in the fields of photogrammetry and laser scanning, have made possible mass acquisitions of heritage artifacts with a particularly high level of geometric accuracy. A processing of the digital model ...
Parallel Particles (P2): A Parallel Position Based Approach for Fast and Stable Simulation of Granular Materials
(The Eurographics Association, 2014)
Granular materials exhibit a large number of diverse physical phenomena which makes their numerical simulation challenging. When set in motion they flow almost like a fluid, while they can present high shear strength when ...
Massively Parallel Batch Neural Gas for Bounding Volume Hierarchy Construction
(The Eurographics Association, 2014)
Ordinary bounding volume hierarchy (BVH) construction algorithms create BVHs that approximate the boundary of the objects. In this paper, we present a BVH construction that instead approximates the volume of the objects ...
