Title: Brigade engine
Post by: LeonhartGR on 2013-03-07 04:47:30

What is Brigade Engine? (http://icelaglace.wordpress.com/2012/09/22/what-is-brigade-engine/)

WIP teaser picture (http://www.facebook.com/photo.php?fbid=547035341997617&set=a.471466862887799.111426.198351220199366&type=1&theater) from future demo, coming soon.

Okay, so he's raytracing. Anybody can do that, it's not impressive. I'll be impressed if this engine can do it in realtime and maintain reasonable framerates on reasonable hardware (no dual GTX 690s in SLI or any such nonsense).

That's what I was thinking. He claims it's realtime, but this guy's using it to render photos not worlds. Impressive photos, yes, but nothing moving.

That's just Covarr's point. Some of those sample vids are peaking at just under 10 fps while holding still and 5-6 while doing the path tracing. If the image isn't moving the result is pretty nice, better than anything Pixar or Dreamworks has ever given us. It looks really grainy while it's rendering too.

It's promising, but the implementation is a little advanced for current GPUs to handle in real-time (at least 30fps).

That's certainly an improvement from before, but I still don't think it's anywhere near ready for primetime yet. The grainy look comes from not enough rays being traced. When  the engine can run with significantly more rays, the grain will disappear. That's also why it looks so much better when there's less motion.

One thing I will say is that ray tracing is the future of kickass graphics. It allows for natural reflections (which would ordinarily require framebuffer effects) as well as natural, high resolution shadows, all at little to no additional compute cost beyond what's necessary to do the ray tracing at all. In fact, the only thing that really doesn't scale nicely when raytracing is additional light sources (more lights = more rays).

You can read all about technical stuff in Hayssam Keilany's FB page http://www.facebook.com/icenhancer he provides some interesting replies. Maybe you can make a few suggestions yourself.
I'm really positive about this engine and looking forward for future updates!

Well, it certainly looks very promising! I look forward to seeing its development :)

Gosh Youtube's new HD compression is terrible. Looks like they got the engine worked out.....

I wonder what specs he's using. It's still pretty noisy, but if it's like that on something mid-high end, I'd imagine it's much better on something absolutely top-end.

Once I've read he's got double titans.
