summary 
The author discusses how to cut down the number of polygons required to model and render the Voyager spacecraft. The geometric problem is to find the tangent lines from a point to a circle. There are two ways to go about solving this, one using gardenvariety analytical geometry and the other using high tech homogeneous coordinates. The author in this column discusses the simple way
