Hardware-Accelerated Lagrangian-Eulerian Texture Advection for 2D Flow Visualization
نویسندگان
چکیده
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.

We present hardware-accelerated texture advection techniques to visualize the motion of particles in steady or time-varying vector fields given on Cartesian grids. We propose an implementation of 2D texture advection which exploits advanced and programmable texture fetch and per-pixel blending operations on an nVidia GeForce 3. For 3D vector field visualization, we present an algorithm for SGI’...

In this paper, we propose a new technique to visualize dense representations of time-dependent vector fields based on a Lagrangian-Eulerian Advection (LEA) scheme. The algorithm produces animations with high spatio-temporal correlation at interactive rates. With this technique, every still frame depicts the instantaneous structure of the flow, whereas an anima...

This report summarizes my research on real-time flow simulation and visualization. In particular, my research is concentrated on efficient GPU algorithms that can exploit the fine-granular thread parallelism of graphics hardware. Several established data structures and numerical solvers perform poorly on the GPU. For this reason, I study and develop new methods that are optimized for the underl...
