for example — for which the path tracing algorithm needs to be tweaked to avoid undue loss of information in smaller samples. It’s possible that with those objects, the algorithm will simply brute force ray trace it instead, to guarantee accuracy. ...
If talking about ray tracing, I've never heard it described as a single ray. It's always been described, as far as I can recall, as something similar to path tracing. It's just that it's never been called path tracing. The only time I've heard single rays being used is to descri...

We then presented a sparse surfel-based approach where we use raytracing to pathtrace irradiance from surfels spawned from the camera. Surfel-based Global Illumination (from GDC slides) We also covered ambient occlusion (AO), and how raytraced AO compares to screen-space AO. ...
In a sense, this history misses the point: for interactive rendering we use whatever gives us the best quality in an allotted amount of time. We usually don’t, and probably shouldn’t, trace rays everywhere, just for the purity of it. Rasterization works rapidly because of coherence exploit...
a technique that uses complex computations to trace the rays of light in a scene to create accurate depictions of how the light would interact with the objects in a scene. This took the world of gaming by an unexpected storm and the whole industry put Ray Tracing as their primary focus go...
