Yes, you’re obviously correct in that Movies != Games. I do think your 10 year projection is a bit pessimistic, I believe it’ll happen sooner than that, especially given the way GPUs are improving year for year, and also given the rate of excellent work in the RTRT segment.

I talked to Larry after his keynote, trying to figure out to what extent their experience is applicable to games. My conclusion is; not much. Iteration time for lighting was perhaps their greatest benefit, which does not apply to games; any lighting technique fast enough to be used for final renders in games is fast enough for rapid iteration by lighting artists. We do have an issue with iteration when prelighting but we are talking about runtime algorithms here. There are other important differences between film and game rendering that apply here. All in all I think we are at least 10 years away from it making sense to use ray tracing rather than rasterization for games; hybrid approaches might start to show up a little faster than that.

See, I told you that RT was more promising than REYES.

The Image Space Gathering paper is now available on NVIDIA’s website (you can find a link on Ke-Sen Huang’s HPG papers page).
