Scalable behaviors for crowd simulation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Crowd simulation for virtual environments offers many challenges centered on the trade-offs between rich behavior, control and computational cost. In this paper we present a new approach to controlling the behavior of ...
Measurement-Based Interactive Simulation of Viscoelastic Solids
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Animation of viscoelastic solids in entertainment and medical applications as well as scientific simulation can be improved through observations of real world objects. This paper presents a method for simulating viscoelastic ...
Point Cloud Collision Detection
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
In the past few years, many efficient rendering and surface reconstruction algorithms for point clouds have been developed. However, collision detection of point clouds has not been considered until now, although this is ...
Real-time Rigid Body Simulation for Haptic Interactions Based on Contact Volume of Polygonal Objects
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time ...
DiFi: Fast 3D Distance Field Computation Using Graphics Hardware
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
We present an algorithm for fast computation of discretized 3D distance fields using graphics hardware. Given a set of primitives and a distance metric, our algorithm computes the distance field for each slice of a uniform ...
Synthesizing Sound from Turbulent Field using Sound Textures for Interactive Fluid Simulation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Sound is an indispensable element for the simulation of a realistic virtual environment. Therefore, there has been much recent research focused on the simulation of realistic sound effects. This paper proposes a method for ...
Immersive Integration of Physical and Virtual Environments
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
We envision future work and play environments in which the user's computing interface is more closely integrated with the physical surroundings than today's conventional computer display screens and keyboards.We are working ...
Image-based Relighting, and Computer Vision
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Image-based techniques have become very popular over the past couple of years. Ranging from modeling to rendering and lighting, the use of images as direct input for graphics algorithms has become as important as processing ...
Interference Detection for Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Accurate and robust interference detection and ray-tracing of subdivision surfaces requires safe linear approximations. Approximation of the limit surface by the subdivided control polyhedron can be both inaccurate and, ...
High Resolution Acquisition, Learning and Transfer of Dynamic 3-D Facial Expressions
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
Synthesis and re-targeting of facial expressions is central to facial animation and often involves significant manual work in order to achieve realistic expressions, due to the difficulty of capturing high quality dynamic ...
