It seems to me that ray tracing has to defeat rasterization in games industry, and, for film rendering, has to defeat REYES. Seems like ray-tracing is having a really hard time these days!
Ray tracing in games
In 2007-08, students of the IGAD course of the NHTV University of Applied Sciences (Breda, The Netherlands) worked on two games using a real-time ray tracer for rendering. Here is the page that describes there work.
Though I did not find any good feedback from that place.
2) Quake 4, Quake Wars and Wolfenstein have been ray traced!
Here are the details.
Quake 3 ray traced : 2004
Quake 4 ray traced : 2006
Quake Wars ray traced : 2008
Wolfenstein ray traced : 2010
All these projects, seemingly, are CPU based.
This article at Intel's research site reports about the Wolf3D getting ray-traced-
- Effects achieved : reflections, refractions,
- Scene complexity: around 1 million triangles ( claimed )
- Performance :
