Hardware-Accelerated Lagrangian-Eulerian Texture Advection for 2D Flow Visualization
Daniel Weiskopf, Gordon Erlebacher, Matthias Hopf, Thomas Ertl · 2002
A hardware-based approach for visualizing unsteady flow fields by means of Lagrangian-Eulerian advection is presented. Both noise-based and dyebased texture advection is supported. The implementation allows the advection of each texture to be performed completely on the graphics hardware in a single-pass rendering. We discuss experiences with the interactive visualization of unsteady flow fields that become possible due to the high visualization speed of the hardware-based approach.
