Position Based Dynamics
(The Eurographics Association, 2006)
The most popular approaches for the simulation of dynamic systems in computer graphics are force based. Internal and external forces are accumulated from which accelerations are computed based on Newton's second law of ...
Kinetic Separation Lists for Continuous Collision Detection of Deformable Objects
(The Eurographics Association, 2006)
We present a new acceleration scheme for continuous collision detection of objects under arbitrary deformations. Both pairwise and self collision detection are presented. This scheme is facilitated by a new acceleration ...
Stable Interactive Cutting of Deformable Objects
(The Eurographics Association, 2006)
In this paper we present a novel approach for stable interactive cutting of deformable objects in virtual environments. Our method is based on the extended finite elements method, allowing for a modeling of discontinuities ...
Non structured meshes for Cloth GPU simulation using FEM
(The Eurographics Association, 2006)
We present a Finite Element Method (FEM) implementation for cloth simulation on the GPU. The advantages of FEM are twofold: the realism of cloth simulations using this method is improved compared with other methods like ...
Explicit Integrators Analysis for a Simulation Engine
(The Eurographics Association, 2006)
One of the most significant elements when dealing with particle based object modeling in virtual reality applications is the integrator used to compute the state of the particles, because it grants the deformation stability ...
Virtual Resectoscope Interface for a Surgery Simulation Training System of the Prostate
(The Eurographics Association, 2006)
In this work is presented the current state of the development of a virtual resectocope interface for a surgery simulation system for training Transurethral Resection of the Prostate (TURP). The interface consists of two ...
Partitioning Meshes into Strips using the Enhanced Tunnelling Algorithm (ETA)
(The Eurographics Association, 2006)
Triangle meshes are the most used representations for three-dimensional objects, and triangle strips are the organization of triangles mostly used for efficient rendering. Since the problem of optimal strip decomposition ...
Simulating Prostate Surgical Procedures with a Discrete Soft Tissue Model
(The Eurographics Association, 2006)
Simulating surgical procedures is still a complex challenge. Either modeling methods or simulators have to take into account specific geometries and properties of the patient organs. In this paper, a new soft tissue modeling ...
Local Constraint Methods for Deformable Objects
(The Eurographics Association, 2006)
We present a local scheme to enforce non-conflicting geometric constraints for dynamically deforming objects. The approach employs information on the underlying numerical integration method and we present a unified scheme ...
Deformable Hybrid Approach for Haptic Interaction
(The Eurographics Association, 2006)
A new hybrid approach for deformable models is presented here and carried out in a virtual reality environment, achieving real time performance with haptic interactions. Our implementation consists in using two approaches ...
