This article is intended to be a follow up article to one released about a year ago through PC Perspective. A lot of things have changed since then. Real-time ray tracing for desktop machines is just around the corner.
How will ray tracing for games hit the market? Many people expect it to be a smooth transition – raster only to raster plus ray tracing combined, transitioning to completely ray traced eventually. They think that in the early stages, most of the image would be still rasterized and ray tracing would be used sparingly, only in some small areas such as on a reflecting sphere.
It is a nice thought and reflects what has happened so far in the development of graphics cards. So it is understandable that people have it in their minds that ray tracing should be introduced in small steps. The only problem is: Technically it makes no sense.
