Abstract:


    Merging ray tracing with real-time hidden-surface algorithms such as the z-buffer algorithm offers a smooth transition from interactive display with approximate soft shadows, reflections, and transparency to full ray tracing with all of its associated effects. This is done by using the ray tracer only for tracing shading rays at the vertices of polygons and using another hidden-surface technique for hiddensurface removal in conjunction with Gouraud interpolation.
