Uncertainty visualization using High Dynamic Range volume rendering.

Vijeth D

Abstract

We propose a method for uncertainty visualization of scalar volumetric data sets using high dynamic range (HDR) volume rendering. We design a transfer function that maps each data point to a color in HDR space. We modify existing tone mapping techniques and suitably integrate them with direct volume rendering to obtain a low dynamic range image that is rendered on screen. The resulting visualization allows the user to study the details in data as well as uncertainty.
