>> Universal Scene Description (USD) is an efficient, scalable system for authoring, reading, and streaming time-sampled scene description for interchange between graphics applications. What does this mean for the layman? I got a 404 for the 'getting help with USD' link

I am going to hazard a guess as nobody else responded. They have a lot of different tools for different aspects (animation,mocap,shaders,texture painting, modelling, rigging, final render etc) and a USD allows them to quickly back-and-forth between the different stages on as-yet incomplete scenes to preview final renders, make fine adjustments further up and down the pipeline to accomodate for changes made elsewhere.

Currently reading The Pixar Touch by David A. Price and they talk a lot about the types of software and standards for rendering they had to create over the years. Incredibly interesting looking back at what they were able to achieve. A talented crew for sure. For those interested: https://www.goodreads.com/book/show/2632830-the-pixar-touch

Thanks for the recommendation. I've always been interested in the rapid rise of Pixar and the consistency in quality they've maintained for these past two decades.

30 years! Although they started out in hardware... talk about a pivot.

How does this compare with DAE, which seems to be the existing standard for this?

Well, DAE is about the most poorly specified file specification on the planet... so I'm going to guess favourably ;)

An interesting format that is not very widely used (hopefully it will be one day) is OpenGEX. Here's a comparison of Collada vs. OpenGEX:

your company? You work for Clevo in China? because this is Clevo P870DM3-G aka Sager NP9873

It looks exactly the same but with a different logo. However the speaker in the video does seem to have the system76 (Bonobo) logo on his Clevo: http://www.gentechpc.com/Sager-NP9873-S-Clevo-P870DM3-G-nVid... Bonobo: https://system76.com/laptops/bonobo

I never knew anyone was building laptops with dual desktop GTX1080s, but you pay for it by having to lug around two 330W power supplies.

Since someone from System76 is on the thread, can you comment on why the System76 version uses a 1080p@120Hz screen instead of 1440p@120Hz like the Clevo?

That's interesting they didn't just collaborate on alembic.io, despite being sister companies.

Speicifcally USD is a: * scene descriptor * geometry caching format * GL Scene Graph viewer

though each of those can exist independently of each other, and it does support Alembic as a geometry backend.

I believe they didn't support alembic because the geometry heritage of USD predates Alembic being a standard, and they added features like overrides etc.

Though interestingly, Blizzard just added support for Alembic layers that would describe overrides as well, so it's definitely an odd situation between the two.

I believe USD with an Alembic backend will be the eventual outcome

Every step of the way they were scheming how to get to feature films -- everything in between sounds like a means for resources (money, hardware, people, so on so forth).

Just why. If you want to work on the go, clean up your damn inbox!

because its cheaper, they are selling lowest possible Clevo configuration in order to reach lowest starting price.
