I don't understand why everyone is so up in arms about this. It's still a great help to toolkit developers, display server developers, and anyone wanting to port operating systems other than Linux -...

Did you try reversing the polarity of the neutron flow?

OK. WE UNDERSTAND.





THERE. HAPPY? We GET IT. But you know what? It's not magic. Of course you can render hundreds of frames per second if you only cast one ray, but if you only cast...

uh... what? I never mentioned anything about capitalism or buying products. I'm just pointing out that a lot of people say "real-time raytracing" when all they really mean is...

Now you're just playing with words. "Real-time raytracing" does not have any hard and fast definition, it just means raytracing at a high enough frame rate & enough detail for a human being to...

Oh geez... I can't find any good screenshots demonstrating an adaptive sampling grid. I may have to resurrect my years-old raytracing code and make some.

When I said earlier that I wrote a...

Because if you haven't got the computing power to cast at least one real primary ray per pixel, you either just leave the rest of the pixels black, or you fill them in based on the colours of nearby...

Which means you're only casting a couple of rays per frame, which means only a couple of pixels have colour values based on the scene itself. The rest of the pixel colours will be made up using...

Dude CALM DOWN. If you actually READ my posts, I'm describing how quality scaling in interactive raytracers is usually done. I know you can scale the quality up/down to hit a particular FPS target...

No, you can't make things magically FPS-less. It's simple.

The maximum FPS is determined by how long it takes to gather one frame's worth of information at the lowest acceptable quality. For...

Sorry, Q, but I've *written* a raytracer and you are very confused. It is true that you can dynamically alter the performance of a raytracer by changing the number of rays cast, but that does not...

Regardless of whether or not mental health issues are an interesting topic of discussion, they're not relevant to this thread.

So, how 'bout those rendering differences, eh?

That's a very cynical attitude - but unfortunately, that doesn't make it wrong, and I find myself agreeing with most of what you said. Sad but true.

Except I wasn't trolling, I was just pointing out a difference in the renderings, and speculating as to what I thought could be causing it. Q responded with a rant about open vs. closed-source...

So Qaridarium should be allowed to continue insulting people, accusing them of being Nazis, whilst someone who accidentally revives an old thread should be prevented from posting for 10 days?
...

Qaridarium, stop derailing this thread, please. The grown-ups are trying to have a meaningful discussion about a discrepancy in the renderings.

Enough is enough.

Wow - it's almost like my original post describing the problem was genuine, and not an attack on free software at all! ;)

Seriously though, I'm glad someone else is seeing the same thing I am, and...

Just to clarify, I'm not in any way against open-source drivers, and didn't meant to imply that in my post. I was just pointing out what I perceived to be a rendering issue. I did respond to Q's...

Why don't you go and write your magical, bug-free driver then come back and tell us how hard it was? Have you ever actually *written* any code?

It might possibly have been a teensy bit ironic had your statement actually been true, but calling something ironic doesn't magically make it ironic. You're currently failing harder than Michael did...
