Render and Ray

This document describes the Alpha_1 rendering programs render and ray which produce shaded images. Render operates with a traditional scanline polygon fill algorithm and a Z-buffer hidden surface algorithm. Ray used a ray-tracing algorithm for more realistic images.

Images are generally produced in the Utah Raster Toolkit (URT) run-length-encoded (RLE) format. URT programs are used to display, convert, or further manipulate the image (e.g., getx11).
