Statistical Simulation of Rigid Bodies
(ACM SIGGRAPH / Eurographics Association, 2009)
We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions ...
Realtime Ray Tracing of Dynamic Scenes on an FPGA Chip
(The Eurographics Association, 2004)
Realtime ray tracing has recently established itself as a possible alternative to the current rasterization approach for interactive 3D graphics. However, the performance of existing software implementations is still ...
Hardware-based Simulation and Collision Detection for Large Particle Systems
(The Eurographics Association, 2004)
Particle systems have long been recognized as an essential building block for detail-rich and lively visual environments. Current implementations can handle up to 10,000 particles in real-time simulations and are mostly ...
A Point-based Method for Animating Incompressible Flow
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper, we present a point-based method for animating incompressible flow. The advection term is handled by moving the sample points through the flow in a Lagrangian fashion. However, unlike most previous approaches, ...
Real-Time Deformation and Fracture in a Game Environment
(ACM SIGGRAPH / Eurographics Association, 2009)
This paper describes a simulation system that has been developed to model the deformation and fracture of solid objects in a real-time gaming context. Based around a corotational tetrahedral finite element method, this ...
Visibility Transition Planning for Dynamic Camera Control
(ACM SIGGRAPH / Eurographics Association, 2009)
We present a real-time camera control system that uses a global planning algorithm to compute large, occlusion free camera paths through complex environments. The algorithm incorporates the visibility of a focus point into ...
Simulating Balance Recovery Responses to Trips Based on Biomechanical Principles
(ACM SIGGRAPH / Eurographics Association, 2009)
To realize the full potential of human simulations in interactive environments, we need controllers that have the ability to respond appropriately to unexpected events. In this paper, we create controllers for the trip ...
Anisotropic Friction for Deformable Surfaces and Solids
(ACM SIGGRAPH / Eurographics Association, 2009)
This paper presents a method for simulating anisotropic friction for deforming surfaces and solids. Frictional contact is a complex phenomenon that fuels research in mechanical engineering, computational contact mechanics, ...
Efficient and Robust Annotation of Motion Capture Data
(ACM SIGGRAPH / Eurographics Association, 2009)
In view of increasing collections of available 3D motion capture (mocap) data, the task of automatically annotating large sets of unstructured motion data is gaining in importance. In this paper, we present an efficient ...
Style Learning and Transferring for Facial Animation Editing
(ACM SIGGRAPH / Eurographics Association, 2009)
Most of current facial animation editing techniques are frame-based approaches (i.e., manually edit one keyframe every several frames), which is ineffective, time-consuming, and prone to editing inconsistency. In this ...
