Abstract
A symbol generator useful for stroke based and raster display systems provides the ability of generating ellipses and elliptical arc segments. A look-up table provides cosine and sine values for incremental angles which are multiplied by major and minor axis scale factors for a selected ellipse. Global input parameters permit rotation of all arcs and vectors to generate orthogonal projections, thereby producing 2-D and 3-D symbology.
