I listened to their explanation and it sounds a bit shady. First they used that old salesman trick of using a British accent to appear smart, so that was already a red flag.

And then their explanation of the secret to their technology sounded rather ridiculous. They said that their technology was like the google search engine or like searching for the word "money" in an MS word document (the latter was the lamest attempt at subliminal messaging you are likely to find outside of a political ad). Needless to say that is a very silly explanation.

Of course a lot of graphics systems have methods where they determine what elements are supposed to be visible and render only those elements. But that is not something that will give you "unlimited detail".

So yeah .... shady.

Come on, there's a lot to be critical about in this video, but do you honestly think he faked a British accent to appear smart? There's a few million of them that talk like that, you know. And the word search for money being lame subliminal messaging? Really?

[hristov]

Maybe I am being unfair, but that accent seemed a bit fake.

[samlittlewood]

Sounded a bit like Lloyd Grossman to me, and 'data' as 'darta'. From some digging around, I think these guys are in Australia. There are a couple of other vowel slips which would fit.

[andrewcooke]

it sounded real to me (an englishman). that didn't stop it sounding extremely annoying.

[arketyp]

Well, then you don't know English.

[jcromartie]

I read this in a British accent.

If I understood correctly, it seems to resemble a search engine in that it takes all the dots that compose the 3D world and search for the ones that need to be displayed to compose the 2D image on the screen at any given viewing angle?

If that is correct, then I think the search engine example is pretty good at explaining it.

Graphics cards already have this functionality, it's nothing new.

[calcnerd256]

Not arbitrarily. Make sure it's nothing new before you say it is. How complicated is the predicate they're searching?

[hristov]

I can say it is nothing new. I have written and seen many patents that describe systems that do that.

As far as the "predicate they are searching" the video mentioned nothing about the predicate other than it is for things that are visible, and that is nothing new.

[calcnerd256]

They could just be being glib. Clipping and LOD aren't the same thing as one another. Consider the 2-D case of sampling a line (uncountably many points) for a raster display. Reimagining our favorite line drawing algorithms as search problems requires a lot of work to figure out how to best search the space. I hope these guys are doing something like that.
