Webintersection is found, the ray is intersected with the height eld. The task of intersecting the ray and the height eld is performed most efciently by projecting the ray onto the base … WebMusgrave's QAEB Tracing for Procedural Height Fields. no source available, but perhaps good for normal grid heightfields; many other algorithms, from the ray-tracing field?

WebRocket ionosphere experiments give the relative delay of a pulsed signal as a function of rocket position. These data are used in an analysis to obtain the electron-density distribution with respect to height. This analysis, which takes into account the effects of the earth's magnetic field and the obliquity of the ray paths, is for the smooth, horizontally stratified … WebMusgrave, F.K.: Grid Tracing: Fast Ray Tracing for Height Fields.
