Texture-based flow visualisation

Introduction

Dense, texture-based vector field visualisation has the goal to show the complete vector field and, therefore, does not miss any important features of a data set. This web page gives an overview of research in GPU-accelerated texture-based flow visualisation that allows for interactive applications.

Projects

IEEE Visualization Tutorial 2004

This web page contains material of the IEEE Visualization 2004 Tutorial on "Interactive Texture-Based Flow Visualization". Interactive texture-based flow visualization has become an active field of research in the last three or four years. Recent progress in this field has led to efficient vector field visualization methods and, in particular, to improved techniques for time-dependent data. This tutorial covers approaches for vector fields given on 2D planes, on surfaces, and within 3D volumes. Both the theoretical background and the GPU-oriented implementations of many of these techniques are presented, along with a demonstration of their usefulness by means of typical applications.

 

Spacetime-Coherent Visualization of Vector Fields

This web page contains additional material accompanying the IEEE Visualization 2003 paper "A Texture-Based Framework for Spacetime-Coherent Visualization of Time-Dependent Vector Fields" by Daniel Weiskopf, Gordon Erlebacher, and Thomas Ertl.

 

Animation of Orthogonal Texture Patterns for Vector Field Visualization

Author: Sven Bachthaler, Daniel Weiskopf

This web page contains additional material accompanying the paper which introduces orthogonal vector field visualization on 2D manifolds: a representation by lines that are perpendicular to the input vector field. Line patterns are generated by line integral convolution (LIC). This visualization is combined with animation based on motion along the vector field.
