(“the Act”), Alliance for OpenUSD Series LLC (“AOUSD”) has filed written notifications simultaneously with the Attorney General and the Federal Trade Commission disclosing additions or changes to its standards development activities.

The Geometry WG will define and evolve the strategy for the description of 3D geometry in OpenUSD. Its first deliverable will be the USD Transformable 3D Geometry Specification that will describe the surfaces and volume representations, spatial transformations, rules of determining primary visibility, and other properties required for imaging those representations.

On October 30, 2023, AOUSD filed its original notification pursuant to section 6(a) of the Act. The Department of Justice published a notice in the Federal Register pursuant to section 6(b) of the Act on December 15, 2023 (88 FR 86939).
