This user guide outlines the use of TIM, an interactive ray-tracing program with a number of special powers. TIM can be customised and embedded into internet pages, making it suitable not only for research but also for its dissemination.

We describe several extensions to TIM, a raytracing program for ray-optics research. These include relativistic raytracing; simulation of the external appearance of Eaton lenses, Luneburg lenses and generalized focusing gradient-index…
