Alembic+ > Pixar's USD:

"USD (Universal Scene Description) is an efficient, scalable system for authoring, reading, and streaming time-sampled scene description for interchange between graphics applications."

I think I set a new record in here: 0 views and 0 replies during 1 month. Well, that was before I wrote this "reply." :)

must be the forum software :) I know I've viewed it but I had no idea what it was for and what kind of problem it solves. Even after I've watched the videos. :mf_prop:

The number of views only updates whenever someone adds a post.

I have the same question... what is the + in Alembic+ ?

Hehe, okay. Didn't know that about the forum's inner workings.

Anyway, I wrote Alembic+ because USD is related to Alembic in the sense that it allows applications to read entire scene data and not just objects and cameras like Alembic does.

I think that being able to access the scene data within Fusion would allow a compositor to generate mattes on a need to have basis. Comper uses a picker of some sort and selects the object he/she needs a matte for and Fusion will generate a trimmed down scene file using USD and that file will be submitted and rendered.

Gotcha, thanks. Interesting stuff. Is this an open standard? Can't seem to find info on that...

Don't think so. But I don't know for sure because I can't find related info either. Pixar's OpenSubdiv is and they are clear about that on the website, not so on their USD page...

from the presentation slides:

We are gauging interest to determine if we want to release USD and its associated IP as an OpenSource project
