Abstract
An algorithm for rendering scalar field data that reduces rendering times by as much as two orders of magnitude over traditional full resolution images is presented. Less than full-resolution sampling of the scalar field is performed using a fast ray tracing method. The sampling grid points are output as a set of screen-based Gouraud shaded polygons which are rendered in hardware by a graphics workstation. A gradient-based variable resolution algorithm that further improves rendering speed is presented. Several examples are presented
