Just asking out of curiosity.. are there any future announcements to come or have we seen them all now ?

One good thing is that the exchange rate is going down slowly.

Am I the only one who's just noticed R2D2 lit by HDRI added to the speed/noise section? I thought that the image of the HDR hadn't loaded properly at first. That's insanely great quality coming from one tiny pin prick of light - amazing. I'm interested to hear how big that hdri is.

It's been there awhile ...but yes, amazing indeed...I've got my $$ ready to fly

The map is 6000x3000. The emitter square is 10 pixels x 10 pixels.

FYI, we've also made successful tests with a single pixel and even close to zenith.

I don't know how that's possible but I can't wait. Roll on...

Not to sidetrack this thread... but I just had to ask ...maybe I should start another thread?

Can one of you guys (Mike or Tom) explain to me how/why you would use such a large hdri (that part I get) with such a small plane 10 x 10 pixels?

Thanks very much in advance for your reply/(ies)!!!!!!!!

Wow thats almost freaky!

I'm neither Tom nor Mike but come to think about ypur question I'd guess it is to get crisp shadows like there's a spotlight/sun (depending on the spot size)

[RichG]

Think about it like using an area light in a conventional 3d package. The larger you make it, the more diffuse your shadows become. But I think that here, they're not especially showing something you'd want to do, it's just a demonstration of the phenomenal accuracy of their HDR solution now.

I think a better question would be how LARGE you can make the lit area and still get crisp shadows? I'm very curious how the new system will look with a normal hdri, of a bright sunny day for example. Will it give the slightly soft shadows you'd expect or will all the light coming from the hdri still wash out the shadows?

I think that would be down to the quality of the hdri, they're not all created equally. If you have a properly calibrated image with superbright whites coming from the sun and gentler illumination coming from the surroundings (in theory) it should look as it would in life.

Look at image nr 6, it's lit entirely with an HDR map with sunlight in it. So now you can get sharp shadows from these HDRs as well. Depends ofcourse how the HDR looks, if it was shot with the sun through clouds, you will get blurrier shadows, or you can blur slightly the illumination HDR for blurrier shadows. But if the sun was clear in the HDR, you get sharp shadows

The R2D2 example is ment to show that even in extreme situations Maxwell V2 can handle these maps VERY efficiently. For example outer space lighting is a lot easier now

O.K- Thanks folks, I get it now!
