Abstract

We present a graphics hardware-based system for interactive denoising, vortex detection, and visualization of vector data. No intermediate results need to be read back by the application once the vector field has been loaded onto the graphics adapter. Due to modern GPUs' parallel processing capabilities, our system significantly outperforms software implementations and thus provides a valuable tool for the interactive exploration of vector fields and the understanding of flow structures.
