PVRTC2

[Lazy8s]

PVRTC received a major update, enhancing their 2bpp and 4bpp formats with improved quality, NPOT support, sub texturing and other refinements.

Did they send Simon to GDC?

 

[Simon F]

Short answer - No. Too busy for that sort of thing

 

[Lazy8s]

Busy can be a good thing.

I want to see some updated comparisons of quality among the different texture compression algorithms. The old page and any mirror of it also seems long gone.

If the 2bpp method retains even more quality of a source than before, a lot of devs are going to be even happier! The update is coming right in time to help devs manage the insane standards set by the new iPad's display resolution.

Do you think PVRTC2 is already in iOS 5.1?

I don't think it's exposed in the software at present.

I don't think it's exposed in the software at present.

We can expect though a relevant whitepaper about PVRTC2 in a reasonable amount of time?

 

[Lazy8s]

Does the PSNR also reflect much of the improved quality of PVRTC2 or is it best reflected in visual observation?

On another note, hopefully HTC and their lawyers learned a lesson last time.

A proper published paper? Unlikely given time constraints. I suspect the publications department might reformat one of the internal ones.

Yes the PSNR does improve. To be honest, PSNR (or equivalently RMSE) is not really a good measure but until I find something that is better, I suppose it'll have to do.

On another note, hopefully HTC and their lawyers learned a lesson last time.

No comment.

How does it compare to ASTC announced with Open GL 4.3?

Are there any Android devices running PowerVR? There have been a lot of complaints from the Linux community regarding the available drivers, has that situation improved?

Nice joke!

Welcome back home at earth after your 10 year long transpluto space mission.

I imagine they'll want to for the retina iPad in the future.

PVRTC2 looks very nice

PVRTC looks like jpg@ 40 (unusable for esp HUD stuff etc) PVRTC2 is like jpg@90
So what old IOS hardwares going to support it?

also related is there a photoshop plugin for PVR for the mac?

 

[iwod]

Bump on this. Any news?

 

[Simon F]

In what sense?

 

[Dominik D]

I guess he's re-asking "Did they send Simon to GDC?" ;] So, did they?

 

[Simon F]

I've never been to GDC
