Title Computer Display of Curved Surfaces
Date 1978
Description This thesis attacks the ?roblem of generating computer synthesized images both more rapidly and more realistically. Increase in speed is achieved by a scan line based algorithm for drawing pictures of parametrically defined curved surfaces. Computation time is reduced by requiring calculation at only a few visually important points along a scan line, and by interpolating intensities between them. The realism is increased by use of shading functions based on semi-empirical models of how light actually reflects off of real surfaces. Other enhancements involve simulation of surface roughness and irregularities by applying perturbations to the properties of the surface as a function of the value of the defining parameters.
