Description: Raytrace3d implements raytracing in an isotropic medium described by a set of velocity nodes, with the nodes being organized into adjoining tetrahedra. Within any tetrahedron, the velocity varies linearly with position, and the raypaths are therefore arcs of circles. The traveltime
along along the ray is a known, analytic function of arc-length along the ray. Thus the major effort in raytracing is the bookkeeping necessary
to continue rays between adjacent tetrahedra. README
