Abstract

The application of transfer functions to map data values to visual properties as, e.g., color and opacity, is a crucial step in direct volume rendering. Due to the complex relationship between the transfer function and the resulting image it is usually extremely difficult to model an appropriate mapping. In this paper we present an advanced transfer function specification scheme for the visualization of medical data. The concept of metadata is used to make the modeling of transfer functions more intuitive. A small number of parameters is sufficient to completely describe a transfer function, thus this specification scheme is suitable for (semi-)automated search techniques.
