Anyone here have any experience with this? I noticed a small booth at ISE recently, saying it hosted HP/AMD, so I walked up and asked one of the guys if they had managed to add edgeblending to the Eyefinity cards, and he told me that the drivers for the pro range did indeed support edgeblending, but as he wasn't from AMD I had to come back later when the AMD folks were around to make sure and ask if, what, how, and so on.

And now I just came across these two clips. The first Eyefinity introduction video, also at some club the year before simply used overlapping projectors, but this year at CES the clip (first link) shows edgeblending. The blend zones are visible, but I doubt there is any gamma or brightness correction used, so that is to be expected.

This looks very promising! I've downloaded the trial; it is vendor card independent and it is way more universal than the code I wrote; so it would work with almost all DirectX applications (games, video players, etc.). I've contacted them to offer my code if they needed.

Let us know what you think. Like I said there should be support in AMD's drivers now. DirectX and OpenGL, it says on the website. No verticalblending as for now, so no 2x2 or 3x2 blends. Vendor independant, well eyefinity, some nvidia and the matrox triplehead ubits, I guess this means it doesn't use the graphiccards processing power to do the warping and blend calculations?

[antorsae]

Can you let me know in which release of Eyefinity they support edge blending?

Re: Nthusim, AFAIK they do use graphic card acceleration/computing to do warping.

Like I said, I was told this by an AMD booth partner, not the AMD folks themselves they weren't at the booth the afternoon I attended the ISE trade show. So sorry I can't tell you the version, or if they weren't simply refering to hard edge blending.

Looks like it was one of these guys, as the name on his badge appeared to be German: http://www.ventuz.com/news/company/139/ise_2011_recap_-_can_touch_this!.aspx.

OpenGL has been doing warping for a long time, so not surprised to see the warping done on the card. Issue will be doing warping, blending, gamma correction, brightness adjustments, and AVC decompression all at the same time.

The Canon Dome turns out to have been running on servers using Firepro cards, the blend looked quite good, unlike last year's small, very dim, and very clear blend zones by AVStumpfle software three projector torus demo. So I suspect this is done using a seperate blend function in the 7thSense server software in combination with the show authoring software adjusting for the blend, http://news.creativecow.net/story/865497.

Searching fireuser.com, there are no results for edge blend, so looks like I was misinformed. That's why, I was asking whether there indeed is support in any of the Eyefinity cards and software.

From the world of PC flight simulation I have seen several cool sw apps.
Scalable Display Technologies appears to be the gold standard but the pricing is a tad steep.

NTHUSIASM I have seen. It is an extension of Sol7

DJs also use some free-/shareware, advantage is those do realtime video, not just pre-rendered, or rendered graphics like the scientific comunity used. Soft-edge blending has been a feature of presentation software like Watchout! and Wings Platinum.
