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.

Ray failures in finite ray tracing
Applied Optics, 1985Le rayon peut manquer la surface geometrique definie par l'equation de surface, il peut subir une reflexion interne totale a la limite milieu dense-milieu moins dense, et la hauteur du rayon a la surface, peut depasser la demi-ouverture indiquee pour cette surface, le rayon peut rencontrer la meme surface apres ...

Algoritmo di calcolo utilizzato nei motori di rendering per simulare il comportamento della luce e dei materiali al fine di emulare i fenomeni tipici che permettono di percepire visivamente la realtà fisica (ad es. colore, illuminazione, ombre, riflessioni, diffusione della luce)

Geometrical ray‐tracing: a ‘ray free’ method
Ophthalmic and Physiological Optics, 1990A new geometrical method of determining the location of the image of an optical component is described. This method does not require rays to be drawn. It can be applied to refractive and reflective components as well as multi‐component systems.
