Ray tracing was brought to a broad knowledge by Whitted [Wh80]. In its simplest form, for each pixel of the image a ray is traced from the …
WebTHEORY OF DYNAMIC RAY TRACING. Conceptually, dynamic ray tracing can be divided into two steps. The first step is the same as geometric ray tracing, from which we get … In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating … See more Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (rays), and that there exists some distance, possibly very small, over which such a ray is locally straight. The ray … See more Astronomy Ray tracing is being increasingly used in astronomy to simulate realistic images of the sky.
