Spacetime visualization of relativistic effects
Ping-Kang Hsiung, Robert H. Thibadeau · 1990
We have developed an innovative ray-tracing algorithm to describe Relativistic Effects in SpaceTime (“REST”). Our algorithm, called REST-frame, models light rays that have assumed infinite speed in conventional ray-tracing to have a finite speed c in spacetime, and uses general Lorentz Transformation, which connects the spacetime description of a single event in two inertial coordinate systems (frames) that differ by a constant velocity, to perform the relativistic translation and aberration of light rays.
