Numerical ray tracing is a procedure that makes use of these equations in order to advance the wave along the ray by an incremented raypath distance. An initial path estimate is perturbed using a geometric interpretation of the ray equations, and the travel time along the path is minimized in a piecewise fashion. By using the API directly, the focus is on highlighting some of the most important new features, functions, and data structures. The main reason why ray tracing hasn't been fully embraced at a larger scale is that traditionally, any real-time ray-tracing application needed a GPU beast running an OpenCL-based algorithm to produce images similar to the one above. Path Tracing work in a similar way, but, once rays reach an intersection point, they act more in a life-like way: They keep bouncing through objects getting more. To deal easily with the various primitive objects, you need to be able to work in all three of the standard 3D coordinate systems: rectangular (x,y,z), spherical polar ( ), and cylindrical polar ( ).
