Discussion:



  • Cary Phillips

  • Joseph Goldstone

  • Nick Porcino

  • Peter Hillman

  • Li Ji

  • Peter: PR #1595 add deep id/manifest tools and co

  •  

    • Need to add reference to Philippe Lafrance as co-author, he wrote the docs as a part of the Weta tools, “how to write Deep nodes.” Was meaning to add the example code generation examples. 

    • Should have a note to the relationship with Cryptomatte. We’re suggesting people switch from Cryptomatte to this.

    • Nuke parses the json every time you move the mouse

  • Nick:

  •  

    • Haven’t had time to track down the compression bug in Core

    • Another bug: I didn’t realize how strong the requirement is that the channels be alphabetically ordered. I accidentally shipped a version of the USD where the channels got flopped. 

    • Peter: the file has to have them ordered. 

    • Nick: I thought we just suggest they’re in order

    • Peter: The C++ API requires them to be in order because it uses a  map to store them. The framebuffer mechanism stores them in whatever order but alphabetizes them as you write. 

  • Li:

  •  

    • Website builder needs exrheader, but on Windows, it needs exrheader.exe. But really it would be better to convert them images and store them.

    • Peter: two cmake targets, one to do the conversion, then commit the generated files to the repo, then another to build the website.

    • We have a Christmas party next week with local startup studios and media companies in the Vancouver area. Most people don’t know about OpenEXR and ASWF. Is there a publicity slide deck?

    • A local Canadian university professor talked to me about collaborting on projects, they have money they don’t know how to spend. Could the ASWF collaborate?

    • Google scholar search for “openexr”. Lots of examples of academic references to OpenEXR!

    • Nick: invite the authors to the meeting?

    • Peter: or invite them to the email/slack.

    • Peter: Could write a survey paper about usage of OpenEXR
