ABSTRACT:
A method for rendering a three-dimensional terrain, the method including providing at least one previous display pixel having a previous ray from a point of view through the at least one previous display pixel to a previous terrain unit intersecting an axis of the previous ray, the previous ray having a length, and computing a subsequent ray from the point of view through a subsequent display pixel, whereby the subsequent ray has a length equal to the length of the previous ray.
