An algorithm is presented for rendering scalar field data which reduces rendering times by as much as two orders of magnitude over traditional full resolution images. 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 is presented which further improves rendering speed. Several examples are presented.
