Abstract

In this paper a high-quality rendering technique for the visualization of 3D scalar fields in an ”aquarium model” is presented. This technique is based on ray casting. The model consists of scalar values defined on a grid, supplemented with glass walls and a bottom. Using trilinear interpolation within the grid is an option. The implementation has been divided into two stages; ray casting, and colour binding using transfer functions are implemented as separate processes. This enables the user to generate different pictures from the same viewpoint, experimenting with different parameters. The method has been applied to data obtained from simulations computing concentrations in sea water.
