Global illumination with path tracing in OptiX

"This is no doubt the future of game graphics"

...and it always will be.

@bernverdnardo1 wanna bet?

[deifo]

Why not render to an offscreen buffer and write to screen a blurred version of that offscreen buffer? That would eliminate the black pixels.

Yes, you'll get a blurry picture until the colors converge, but that would be subjectively better IMO.

But what about dynamic objects? does it have to reconstruct the acceleration structure(kd tree, etc)?

[SuperGastrocnemius]

@NutsandGuts each dynamic object uses a separate BVH in OptiX, soon it will use HLBVH. It's very fast and allows for thousands of dynamic objects to be updated/rebuilt simultaneously at high framerates. So expect dynamic raytraced or pathtraced demos soon.

I've been dreaming of the day where we can play games using path tracing for a while! I'm sure it will be possible very soon, at least on very high-end systems. If that day ever comes it will be strange, because instead of people with bad computers just having bad framerates, they will be able to have a tradeoff between framerates and noisy pictures.

[SuperGastrocnemius]

@Phygar1 Me too! I also believe it will be possible "soon", like in 1-2 years, at low res and with some noise but not too obtrusive. Just look at the Brigade engine developed by Jacco Bikker: youtube"dot"com/watch?v=Jm6hz2­-gxZ0 Very exciting stuff, that could start a little revolution for game rendering.

@Phygar1 Me too. I can't wait until the Bohemia Interactive include this in their war sims. =) Will it come to Arma 3 maybe? =]

[nazurea]

@MrKarlalfred88 no.

[MrKarlalfred88]

@nazurea you are right. probably not. :) that game is too complex for that. :) but it will still come to other games. I believe so.

Wow!
