On Mesh-Free Valley Surface Extraction with Application to Low Frequency Sound Simulation
Found in: IEEE Transactions on Visualization and Computer Graphics
By Harald Obermaier,Jan Mohring,Eduard Deines,Martin Hering-Bertram,Hans Hagen
Issue Date:February 2012
pp. 270-282
Crease surfaces describe extremal structures of 3D scalar fields. We present a new region-growing-based approach to the meshless extraction of adaptive nonmanifold valley and ridge surfaces that overcomes limitations of previous approaches by decoupling po...
Phonon Tracing for Auralization and Visualization of Sound
Found in: Visualization Conference, IEEE
By Martin Bertram, Eduard Deines, Jan Mohring, Jevgenij Jegorovs, Hans Hagen
Issue Date:October 2005
pp. 20
We present a new particle tracing approach for the simulation of mid- and high-frequency sound. Inspired by the photorealism obtained by methods like photon mapping, we develop a similar method for the physical simulation of sound within rooms. For given s...
Visualization of Intricate Flow Structures for Vortex Breakdown Analysis
Found in: Visualization Conference, IEEE
By Xavier Tricoche, Christoph Garth, Gordon Kindlmann, Eduard Deines, Gerik Scheuermann, Markus Ruetten, Charles Hansen
Issue Date:October 2004
pp. 187-194
Vortex breakdowns and flow recirculation are essential phenomena in aeronautics where they appear as a limiting factor in the design of modern aircrafts. Because of the inherent intricacy of these features, standard flow visualization techniques typically ...
