This paper describes an algorithm for clipping and capping polyhedrons and a display system for three-dimensional finite element math models to facilitate viewing internal surfaces in the form of continuous tone computer generated color images. A plane is passed through the model with the result that the elements (or portions thereof) on one side of the(More)
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(More)
