Virtual Rheoscopic Fluids

by Florian Hecht, Peter J. Mucha, Greg Turk
"... Abstract — We present a visualization technique for simulated fluid dynamics data that visualizes the gradient of the velocity field in an intuitive way. Our work is inspired by rheoscopic particles, which are small, flat particles that, when suspended in fluid, align themselves with the shear of th ..."

Stable Fluids

by Jos Stam , 1999
"... Building animation tools for fluid-like motions is an important and challenging problem with many applications in computer graphics. The use of physics-based models for fluid flow can greatly assist in creating such tools. Physical models, unlike key frame or procedural based techniques, permit an a ..."

an animator to almost effortlessly create interesting, swirling fluid-like behaviors. Also, the interaction of flows with objects and virtual forces is handled elegantly. Until recently, it was believed that physical fluid models were too expensive to allow real-time interaction. This was largely due

Emergent order in rheoscopic swirls

by Michael Wilkinson, Vlad Bezuglyy, Bernhard Mehlig , 2010
"... We consider the ordering of particles in a rheoscopic fluid (a suspension of microscopic rod-like particles) in a steady two-dimensional flow, and discuss its consequences for the reflection of light. The ordering is described by an order parameter which is a non-oriented vector, obtained by averagi ..."

Particle-Based Fluid Simulation for Interactive Applications

by Matthias Müller, David Charypar, Markus Gross , 2003
"... Realistically animated fluids can add substantial realism to interactive applications such as virtual surgery simulators or computer games. In this paper we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate fluids with free surfaces. The method is an extension ..."

Reevaluating Amdahl’s law

by John L. Gustafson - Commun. ACM , 1988
"... At Sandia National Laboratories, we are currently en-gaged in research involving massively parallel process-ing. There is considerable skepticism regarding the via-bility of massive parallelism; the skepticism centers around Amdahl’s law, an argument put forth by Gene Amda.hl in 1967 [l] that even w ..."

How can this be, when Amdahl’s argument would predict otherwise? The expression and graph both contain the implicit

Image Mosaicing for Tele-Reality Applications

by Richard Szeliski , 1994
"... While a large number of virtual reality applications, such as fluid flow analysis and molecular modeling, deal with simulated data, many newer applications attempt to recreate true reality as convincingly as possible. Building detailed models for such applications, which we call tele-reality, is a m ..."

Physically Based Deformable Models in Computer Graphics

by Andrew Nealen, Matthias Müller, Richard Keiser, Eddy Boxerman, Mark Carlson - EUROGRAPHICS 2005 STAR – STATE OF THE ART REPORT , 2005
"... Physically based deformable models have been widely embraced by the Computer Graphics community. Many problems outlined in a previous survey by Gibson and Mirtich [GM97] have been addressed, thereby making these models interesting and useful for both offline and real-time applications, such as motio ..."
Abstract - Cited by 164 (3 self) - Add to MetaCart
, while specifics are left to the respective models. Finally, we discuss areas of application, such as elastoplastic deformation and fracture, cloth and hair animation, virtual surgery simulation, interactive entertainment and fluid/smoke animation, and also suggest areas for future research.

Virtual Machine Support for Dynamic Join Points. In: AOSD’04,

by Christoph Bockisch , Michael Haupt , Mira Mezini , Klaus Ostermann , 2004
"... ABSTRACT A widespread implementation approach for the join point mechanism of aspect-oriented languages is to instrument areas in code that match the static part of pointcut designators, inserting dynamic checks for that part of matching that depends on run-time conditions, if needed. For performan ..."
Abstract - Cited by 99 (16 self) - Add to MetaCart
. For performance reasons, such dynamic checks should be avoided whenever possible. One way to do so is to postpone weaving of advice calls until run-time, when conditions determining the emergence of join points hold. This calls for fluid code---code that adapts itself to the join point emergence at run
