An Improved Jacobi Solver for Particle Simulation
(The Eurographics Association, 2014)This paper presents a new method for simulating particles for computer graphics and video games, based on an improved Jacobi solver and a hybrid approach between velocity time stepping and position based dynamics. Current ... -
Information Fusion for Real-time Motion Estimation in Image-guided Breast Biopsy Navigation
(The Eurographics Association, 2014)A real-time delivery of accurate soft-tissue intervention navigation information is one of the most crucial aspects for accepting the soft-tissue navigation systems for intra-operative use. Currently, soft-tissue navigation ... -
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 ... -
Massively-Parallel Proximity Queries for Point Clouds
(The Eurographics Association, 2014)We present a novel massively-parallel algorithm that allows real-time distance computations between arbitrary 3D objects and unstructured point cloud data. Our main application scenario is collision avoidance for robots ... -
Mechanical Modeling of Three-dimensional Plant Tissue Indented by a Probe
(The Eurographics Association, 2014)Morphogenesis in a developing organism depends on the mechanics of the structural elements of the organism. In plants, typical experiments involve indenting tissues with a probe and measuring the force needed to reach a ... -
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 ... -
A Parallel Architecture for IISPH Fluids
(The Eurographics Association, 2014)We present an architecture for parallel computation of incompressible IISPH simulations on distributed memory systems. We use orthogonal recursive bisection for domain decomposition and present a stable and fast converging ... -
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 ... -
SutureHap: A Suture Simulator with Haptic Feedback
(The Eurographics Association, 2014)Surgical procedures require a high degree of complexity and difficulty. Consequently, extensive preparation in the learning process of medical students is necessary in order to perform suturing tasks successfully. Some ... -
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 ... -
Virtual Fitting Pipeline: Body Dimension Recognition, Cloth Modeling, and On-Body Simulation
(The Eurographics Association, 2014)This paper describes a solution for 3D clothes simulation on human avatars. The proposed approach consists of three parts, the collection of anthropometric human body dimensions, cloths scanning, and the simulation on 3D ...
