Ray tracing is a method to produce realistic images; it determines visible surfaces in an image at the pixel level (Appel, 1968; Kay & Greenberg, 1979; Whitted, 1980). Unlike the z-buffer and BSP tree, ray tracing operates pixel-by-pixel rather than primitive-by-primitive.

An iterative ray-tracing method described by T Smith is shown to give a divergent sequence of approximations in certain cases; when it converges it has only first order convergence according to Hartree's classification of iterative processes An iterative method which always gives second order convergence is described and the significance of the ...

The results of measuring the ray trace speed and compilation speed of thirty-nine computers in fifty-seven configurations, ranging from personal computers to super computers, are described. A correlation of ray trace speed has been made with the LINPACK benchmark which allows the ray trace speed to be estimated using LINPACK performance data.

SPIE Proceedings, 1990
This paper presents a new linearized ray-trace technique for analysis of general optical beam trains, developed for integrated structures/optics/controls design of spaceborne optical instruments. Computer routines based on our approach are fast enough to be executed in-line as part of a spacecraft dynamic simulation or as part of a real-time controller.
