Continuous field visualization with multi-resolution textures

Abstract

A method of using a texture mapping approach to color scales is described, for the purpose of visualizing continuous field scalar quantities. The technique is most appropriate where high gradients are present in the data, or where geometric surfaces are projected to significant screen area. The use of texture mapping takes advantage of widely available 3D display systems for interactive visualization system design. The technique yields a significant reduction in visualization artifacts caused by color interpolation. Multiple resolution textures are shown to improve visualizations of high dynamic range data.
