📌 A .USD data item encompasses a custom 3D scene stored in the Universal Scene Description (USD) layout, designed and implemented by Pixar Animation Studios company. Particularly, the current .USD file elements store appropriate information regarding pinpoint 3D scenes, which involve 3D references to external assets integrated into an accurate scene, shading data, and geometry.
In retrospect, the .USD algorithm was initially designed by Pixar for better compliance with their 3D graphics pipeline for their native animated compositions and scripts. One of the keypoint advantages of the .USD approach is its interchangeability, which enables diverse 3D apps and toolkits utilized within the Pixar 3D graphics pipeline to alter, assemble, package, open, and define the respective 3D content in the .USD file layout.
Another crucial leverage of the .USD extension methodology is its adaptation for collaboration. This tweak suggests interference with different peculiar “layers” in the data layout which are distinguished as separate assets that different collaborating colorists and graphical artists may non-destructively work on in the individual manner and combine their mutual efforts together to form and establish a single common composition or scene.
The .USD tagged marker is a generic label entitlement applied by versatile .USD file entries that can be flawlessly saved in the ASCII shape or commercial “crate” binary structure. Nevertheless, .USD-shaped object samples stored in the “crate” arrangement normally utilize the .USDC label, while those of the data nodes which are covered by ASCII algorithm traditionally grasp the .USDA data marker.
Warning: The .USD-tailored file specification is distributed and shared on the open source principle.
📌 The .USD-formatted data elements can be easily and flexibly unpackaged and opened by Autodesk Maya, NVIDIA Omniverse, SideFX Houdini, or Pixar Animation Studios USD software suites, entirely focused on designing 3D graphics for proficient visual animations and scenes.
