No flame bait, but more like a seething hatred for the comments made by him at Rage3D.


Final Fantasy-level graphics would be incredible. It would be very, very close to real-life; and in real time too!

Maybe we could mess with him and create a special folder on the forum called Trolls, then just move his (and other trolls') posts to that folder.

Cotita, there is

bbcode, thank you for using it...

I fail to see what you are saying here other than "I'll believe what I see with my own eyes", which is 100% your right, but adds little to the debate.

And... I think I'll stop posting in there for a while... That took me enough time already, and yes I am savvy with my time.

Most of what I wanted to say in all those posts is perfectly summarized by Stealthawk (with the exception that I do think it matters, but that's another story).

I was also looking for some technical debate on the possibilities of the nv30, but it seems to me I am alone to debate that, so sooner or later I would have to recognize it and give up posting here for that debate, and sooner is always better.

Have fun all and who knows, may be see you later?

Those pics were not rendered with an NV30 anywhere near the machine that rendered them. Possibly because there may not even be any working NV30 samples yet, but in any case, there certainly weren't months and months ago when these pics were rendered.

The Killeroo pic posted at sharky's briefly was done using path tracing, which couldn't be accomplished in anything like real time on the NV30.

Oh, and 1Ghz DDR-II on a 128-bit bus would give roughly 16 GB/s bandwidth (or less, if you want to use the 1024 convention for storage instead of the 1000 convention for signaling... so confusing).

Like has been stated, the idea behind the pics is not that they were made w/ an NV30, but that NV30 should be able to do them near real-time.

I think it's a load of bull.

Just like the 1024 max instructions.

Whoops! We meant 256, just like r300!

Our bad!

Default A little follow-up...

Just a quick post for those who were interested in my previous posts in the "Doom 3 who cares" thread in the previous forums, in which I was mainly discussing the possibility of real time ray tracing on new generations gpus (for the record, I first posted about it the 16th of June, 2002).

It might looks like I'm not the only one to think that we will see that one day, and it looks like I'm a damn pessimist compared to some other fools...

You can listen to the fools here, go to the very end for a short discussion about shadows.

Have fun!

Talking ...update...

Guess what?

I just ran a real-time ray tracer demo, at 24 fps. Yup. On what super-duper computer, do you ask? Well, on my desktop PC, why?

But there is good news and a bad news.

Let's start by the bad news. It is at 320x200. Kind of reminded me Doom 1! With full options (and that includes the depth of field) at 1024x768, the average framerate drop at 0.61 fps. Hum...

The good news now. The pictures are not computed by a powerful, parallelized GPU, but by a mere CPU (a P4 1.9GHz with RDRAM-800, if you ask).

So...

1. That does prove that real time ray-tracing is not some inaccessible science-fiction fantasy,

2. Given the speed increase that a GPU can give to such parallelizable computations other a CPU, I expect such a demo to run smoothly at decent resolution (that starts at 640x480x32 for me if the image quality is good) when running on a next-gen GPU (but probably without all the options). (but I agree that's a risky expectation, I really don't have the time to detail check it).

We know already that real-time ray tracers can be programmed as kernel ray-tracers and that it enables them to run on next-gen GPUs. The only question that I see remaining is, how far will it be possible to put eye-candy options in the raytracer?

Needless to say I will be looking for the answer to that with a great interest...


Meanwhile, if you wish to see some Doom1-like images, go there!

Have fun!


(and thanks to 3dchips-fr.com for the news!)

I think it could be done but it won't happen. Ray-tracing with high polygons at the same time it'd run like a slide show. Half-Life on a low res might work (that sort of thing)

But I know nothing about this sort of thing.
