Abstract
Surface fill using Bresenhem algorithm concepts can be adapted to handle the hidden surface and shading functions required in solids modelling. A first plurality of vector generators provides the surface fill function, a second plurality of vector generators provides the hidden surface function, and a third plurality of vector generators provides the shading function. All three pluralities of vector generators can be run in unison to increase the speed at which images of solids can be generated by a factor of 1000.
