Abstract

Direct volume rendering (DVR) is a very useful visualisation technique. However, the difficulty in specifying a suitable transfer function often discourages its application to visualisation problems. This work presents a technique for providing meaningful and fast visual feedback that greatly facilitates the transfer function specification process. The feedback is based on a slice-based preview of the actual volume rendering that can be calculated in real-time and can be superimposed on a slice-based view of the data that is being rendered.
