Huygens wavefront tracing: A robust alternative to conventional ray tracing |

A robust alternative to conventional ray tracing

**Paul Sava and Sergey Fomel**

We present a method of ray tracing that is based on a system of
differential equations equivalent to the eikonal equation, but formulated
in the ray coordinate system. We use a first-order discretization scheme
that is interpreted very simply in terms of the Huygens' principle. The
method has proved to be a robust alternative to conventional ray tracing,
while being faster and having a better ability to penetrate the shadow
zones.
