What is USD? Pipelines capable of producing computer graphics films and games typically generate, store, and transmit great quantities of 3D data, which we call “scene description”.  Each of many cooperating applications in the pipeline  (modeling, shading, animation, lighting, fx, rendering) typically has its own special form of scene description tailored to the specific needs … Read moreIntroduction to USD

The Simplest Approach to Subject Classification

Museums, galleries, archives, and many libraries – as well as a host of online databases of various types – seek a simpler approach to subject classification. This paper poses the question: “What is the simplest approach to subject classification?” It suggests a synthetic approach which pursues a sentence-like approach to classification. Such an approach not coincidentally has the added advantage of best capturing the nature of a work.

Subject Classifications in the Scientific and Overall Digital World

Then we trace the structural limitations … Read moreSubject Classifications in the Scientific and Overall Digital World
