Carmack Speaks On Ray Tracing, Future id Engines

Vigile writes "As a matter of principle, when legendary game programmer John Carmack speaks, the entire industry listens. In a recent interview he comments on a multitude of topics starting with information about Intel, their ray tracing research and upcoming Larrabee GPU. Carmack seems to think that Intel's direction using traditional ray tracing methods is not going to work and instead theorizes that using ray casting to traverse a new data structure he is developing is the best course of action. The 'sparse voxel octree' that Carmack discusses would allow for 'unique geometry down to the equivalent of the texel across everything.' He goes on to discuss other topics like the hardware necessary to efficiently process his new data structure, translation to consoles, multi-GPU PC gaming and even the world of hardware physics."

    It as if hundreds of ray tracing fanboys cried out at once, and were silenced.

      It's the most realistic possible way of rendering, so when computers get fast enough we'll be able to everything with ray tracing.

      When that happens, will it also become possible to wield a flashlight and a shotgun at the same time? Or is there some kind of fundamental law against that, like how you can't know the position and velocity of a particle at the same time?

      I already have a QGPU in my computer, though I think it died... I should pop open the case and take a look.

    So, let me get this straight, intel says their baby is the best. Nvidia says theirs is the best. And Carmack is making his own, and saying his is the best. Wow, these articles have all been so informative. I could not possibly have predicted those outcomes.

    The Church of Carmack condemns your post, a profuse apology and confession is now your only hope to salvation. Belief in ray casting will put you down the road to truth and righteousness! But seriously, Carmack created the FPS genre and is still a leader, which makes him one of the most experienced in his field, so, you know, that kind of helps in creating a "god-like" status, or if your still skeptical, a "mini-god" status. okay, how is "almost-god" sound? At least put the word "God" and "Carmack" in the same sentence somewhere, preferably next to each other...
