Nvidia Raytraces the Moon Landing

[Cypher-Jackson]

How could they possibly have landed on the moon without ray-racing in the first place?

If there is light, anything will drop a shadow unless it's a blinding light reflecting of something.

That's the entire point of the original tech demo. To prove that the lunar soil can bounce off enough sunlight to sufficiently light up something within an object casting a shadow from the sun.

Which would mean his whole suit belly would be bright. But wasn't.

??? Lunar soil albedo isn't that high.

Just the valves looked like they were stuck there without any material properties other than basic specular map which gives it that fake shine. Which just makes no sense. Or the rectangular thing on the lunar module that also sticks out in the video like it was placed there without any normal and specular map what so ever.

It looks more like they were following basic physically based shader material principles and didn't bother with anything more than coloring.

 

I mean it obviously sounds like you know a lot more than NVIDIA's developers. So why don't you go create your own? With blackjack and hookers?

mwahahahahahaaaaaa~ this article reminded me RTX still existed XD the games sure as hell aren't.

Ah yes, the usual "why don't you do it". Whatever. If it looks so horribly off I don't need to recreate anything.

Piggy-backing off this; the Albedo of the lunar surface is around 0.12 or so.

 

That's less reflective than most soil material on Earth.

FAKE. everyone knows the earth is flat ffs!

The thing is that it doesn't seem to be a really challenging scene either, so its not that impressive. Itll become impressive with large number of light sources, of different models, with raytraced participating medium, caustics, snow, sand etc.

You are thinking of it like a computer game where the scenery and physics are all controlled engineered by the computer/artist, their primary goal here is to be as accurate as possible with the physical conditions, not make them look pretty by being able to control light angles, materials, etc. 

 

If you don't like the way a window looks in a game you can change it's refractive index and it will look better in the game,  they are not going to change the refractive index of space suits and valves etc just to make it look prettier, they are trying to recreate as realistic representation of what it actually looks like from the source material. They are trying to be as true to the original with very limited input data. 

 

 

It's Nvidia, if they wanted they could bend the the light, add some colors and shit and make the moon dust look amazing, but that's not their goal.

[TheNamelessOne]

Aha now we know how they faked it. Their secret has been revealed. Muahahahaha

The amount of times people make claims like that is amazing.

 

 

>company invests millions of dollars using top end hardware/talent and puts their reputation on the line producing something.

>Internet random claims the output could have been done by a monkey in a basement.

 

If the end of 5 years work by people way more professional than us, using hardware we can only dream about and with Industry support from Nasa and Nvidia, is some how lack luster to our eyes, then maybe we are not considering half of what they have done and the limitations they might have faced.

I'm not the one complaining about it not looking good...

I'm saying that they are recreating a not so complex scene from a rendering complexity.

So it should be easy then right? Probably could have done it on 10-20 year old tech?

This is such an awesome waste of money that its worth it!

Well it's not a huge leap forward no... its nice bit it's in no way groundbreaking

didn't answer the question.

 

EDIT: Don't forget this is the quality of their source material:

 

 

that and a few higher res photo's.  It's not like they have access to a MAYA data bank of this stuff that they can just manipulate, they have to extract all the data from this.

And NASA deleted the original high quality recordings. The best we've got is low quality videotapes of the live broadcast and a Super 8 film recording of one of the primary down-link monitors.

How can something so important in history be misplaced...

 

Well, we can always have Nick Cage find it in exchange for a movie.

The story is that in the 1980's NASA erased and reused the tapes. After the moon landing Congress began cutting away at NASA's budget. Faced with a shortage of data tapes and no money to buy new ones they instituted a policy of erasing and reusing old tapes from previous programs. It's likely the tapes were erased without anyone realizing what they were.

Sooooooooo Dulllllllll, RTX was such a bad choice on their part. We've lost 3 years in performance for a technology that inst supported and no one cares about.

Just my thoughts exactly! We have proof now! It was rendered on an Nvidia graphics card!!

The same thing happened in the past and most if not all of those features are now in every modern GPU.

if we landed on the moon then why is the mission named after apollo the sun god? wake up people we never landed on the moon we landed on the sun

Agreed but the price gouging is worse than ever.

The price gouging is so bad even AMD are starting to make profits.

ILM was doing this for Disney on 4 Quadros/Titans IIRC in real time. So no, not 10-20 year old tech, but it was possible... fitting it in 1 pc is new and special. Doing it at all is not.

Again that is working with completely controlled environments and pre rendered artwork. They didn't create toy story from a grainy 50year old barely understandable video.  From what I understand big hero 6 took months to render on huge render farms and it only had 127 traces per frame (happy to be corrected on that given I didn't look it up and operating on memory). This is an interactive recreation from that first video (meaning it recreates all the traces as you move the mouse).
