On the basis of a new ray tracing idea, a program has been developed which simulates the propagation of sound in an environment. The unique feature of the method is that both the room and the ray are represented only in discrete points. The program is of great use at the planning stage of assembly h

It is well known that eikonal solvers provide a fast and accurate way to compute traveltimes in complex media. However, they only give solutions corresponding to first arrivals. In (J. Comput. Phys. 128, 463 (1996)), J. D. Benamou presents an algorithm which gives a multivalued traveltime solution o

This paper is concerned with field estimation by the ray tracing method (RTM) in two-dimensional (2D) tunnels with arbitrary cross section whose dimension is relatively large compared with the wavelength. The tunnel wall is approximated as a combination of plates. We investigate the accuracy of RTM

It has been shown that height field ray tracing efficiency can be improved by traversing rays in steps across evenly spaced inverted cones of empty space centered above height field cells. This approach, referred to as linear parametric height field ray tracing, has previously been extended by direc
