Dr TIM: Ray-tracer TIM, with additional specialist scientific capabilities
Description
This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract 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 generalised focusing gradient-index lens (GGRIN) lenses, which are types of perfect imaging devices; raytracing through interfaces between spaces with different optical metrics; and refraction with generalised confocal lenslet arrays, which are particularly versatile METATOYs. Title of program: TIM Catalogue Id: AEKY_v2_0 Nature of problem Visualisation of scenes that include scene objects that create wave-optically forbidden light-ray fields Versions of this program held in the CPC repository in Mendeley Data AEKY_v1_0; TIM; 10.1016/j.cpc.2011.11.011 AEKY_v2_0; TIM; 10.1016/j.cpc.2013.10.031
