Pixar OpenSubdiv and Autodesk webinar

[Daniel Brassard]

Originally posted by Graham on Si-community.

 

Next Tuesday, the 23th, yours truly will be hosting a webinar with special guests, Bill Polson, Dirk Van Gelder, Manuel Kraemer, Takahito Tejima, David G. Yu and Dale Ruffolo, from Pixar Animation Studios’ GPU team, to show how Autodesk and Pixar are working together to build technology with stunning real-time results and how real time display of subdivision surfaces helps artists be more productive, and how this code is open source and engineered for ease of integration.

OpenSubdiv is a set of open source libraries that implement high-performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures. The code embodies decades of research and experience by Pixar.

Here's a link to the webinar: Join Pixar Animation Studios, to learn about the OpenSubdiv Project

The webinar page has different links depending on what general time zone you're in, so be sure to choose the right one.

Webinar will be in English only.

Amazing stuff.   Since I an remember, I was dreaming of the day this would become a reality - and it's surpassed those dreams

Crease sets didn't exist before? Been creasing in SI for years!

All the CPU/GPU computing, tesselation etc was very cool though, exciting times ahead where we'll have way more info on screen.

Thanks for posting the webinar!

I guess the real advantage with the creases is with the new adaptative tesselation, so it adds geometry where it needed, sometimes with creases you have to get your subdivision level quite high because it's uniform to have decent creasing, with adaptative it would only add geometry where it's needed to maintain the limit of the surface.

[Graham Bell]

Creasing and Crease Sets have been around in Maya for a while. 2014 has a far better Crease Set editor though, similar to what's seen in the video.

Yes, if it's presented with the tessellation improvements in mind it makes sense.
The way he was talking about it in the webinar made it sound like creases were a new concept that allowed him to have the same result as packing up your edges to visually crease your geometry, making it much less of a pain each time the director asked to modify the model.

That would make perfect sense.

 

Maya subdivision technology has been licensed from Pixar for years. But to what extent is not clear.

Pixar's SDS "technology" has been licensed from everybody and their dog for years, actually.
Thanks to some patents granted on creasing it was either doing that, or risking litigation, or offsetting whole sets of features from the way they would have looked in PRMan.

In theory only the RR semi-sharp creasing algorithm is patented, and some vendors worked around it with different methods, but it's always been slightly ubiquitous and many bigger fishes decided not to risk it, or simply to align to PRMan's look for those, and license away.

Soft has had the same Pixar licensing note forever, and Houdini could render creases in SDS in PRMan for ages, but not in Mantra, due to the same patents (RR SS creasing). Air, 3Delight and MRay work around it with different algorithms.

This new openSubD stuff is really interesting, I do resent they had to go for the MS open source licensing though (MS-Pl I think), but it seemed unavoidable given the collaboration, and all in all it's not too bad a license anyway.

[Luc-Eric Rousseau]

Softimage didn't license from pixar and the tessellation and creasing
implementation are not the same.
On the maya side, it's been co-developed and licensed from pixar and
fully compatible.

[Raffaele Fragapane]

I stand corrected, had been told otherwise time ago though.
I'm curious then, what was the Pixar licensing/copyright notice for then?

Probably for the .TIFF lzw thingy.

[Raffaele Fragapane]

Didn't the unisys(sp?) one expire literally a decade ago, and all others 7 to 8?

[Matt Lind]

Use of PIC and PICT file formats in image libraries?

[Luc-Eric Rousseau]

There was, perhaps still is, a pixar patent notices in Softimage
related to mental ray anti aliasing.

[Pingo van der Brinkloev]

Yeah, something as silly as the help button. You know that small questionmark you click and it takes you to the online docs in a webbrowser? Very helpful!

Well in 2014 when i click or press F1, it takes me to this Autodesk SI startup menu instead - That is it shows me a glimpse of what seems to be the right help page, but then rushes on to the menu, and I have to search for whatever issue I might have from there.

Anyone else experiencing this? It's really bugging me.

Cheers all!

Pingo

[Thomas Volkmann]

Damn, you are right! Help!!

SDK guide works fine though.

Hi,

We are already working on this issue. It will be fixed, as soon as possible. Sorry for any inconvenience..

Awsome news Hemadri!

What I can say about is that it actually go in ther right page (I can see that) and then, after a second, it redirect to the main page.

Eeh.. and now it works (?)

Really.. It does. Didn't do anything other that restart since last.

Haha it works for me to. Must have been something in the online help then. Great work AD!

Yes, this issue has been fixed. By mistake, the relevant context-sensitive Help topics were redirected to the main page in the Online Help. Thanks for your patience..
