It's really exciting to see the things growing from the roots of what USD provides. As the delivery format for AR, USDZs can be authored to target a specific Apple device, letting you tailor the experience for your audience. On the Apple Developer site, there are command line tools to allow you to automate processing of batches of assets. obj, alembic, and a wide variety of other 3D formats as well. Last year, we released Realitåonverter, a stand-alone utility to allow easy creation of a self-contained USDZ from collections of USD files. But it's also the front-end for a full featured pipeline that delivers USDZ for AR and e-commerce and assets for offline rendering. ![]() USD naturally allows creation of USDZ files for AR content. USDZ is the archive package for USD and inherits most of these features, is optimized for sharing, and allows a single file to contain all the resources needed for rich AR interchange. And USD is built with collaboration as a core feature, allowing for many artists to work on a single scene without getting in each other's way. Pixar developed USD for its use in films, so representing millions of objects is the typical case. USD supports all of this and is additionally designed to be highly scalable. These usually support multiple models that can be laid out in a scene graph and have varying levels of support for material and definitions. Then there's a large group of more modern file formats. It has limited support for materials and no support for animations. obj, which often essentially contains just a single 3D model. ![]() Let's take a high level look at other formats out there today. The USD forum is active and full of core contributors answering queries, and the Academy Software Foundation has a working group that meets regularly to gather input from interested groups. Pixar is using an open and collaborative model that the USD project has been following. It's built on decades and decades of production experience in the film industry and is increasingly being adopted for games, simulation, AR, manufacturing, and e-commerce. It's inherently extensible by design and is rapidly emerging as a key workflow technology. USD-based workflows are highly collaborative, enabling you to work independently on parts of an asset, easily incorporating your changes with others. We at Apple worked with Pixar a few years ago to develop the USDZ format to utilize USD in a single file to deliver rich AR content directly to your devices. ![]() USD was developed by Pixar to enable them to create the enormously complex movies we love. Render, collaborate, for games, AR, film all with USD at the center. USD is a foundational technology that, with the growing and deepening integration into Digital Content Creation tools, is enabling more and more ways of creating assets and content. The flexibility of USD can be a core component of an extensible, collaborative, 3D pipeline. ![]() From object capture, asset creation, layout and editing to rendering quick thumbnails for sharing or feedback to creating USDZ assets for use in Augmented Reality, or AR. USD is a set of libraries and file formats that allows for assembly, interchange, and organization of any number of assets into scenes, shots, or virtual objects. We'll talk a little bit about what USD is, take a look at the exciting developments n the world of USD, show some incredible new features in Preview, and demonstrate how USD can be at the center of a creative 3D workflow. My name is Doug, and today my colleague Nate and I will take a look at how Universal Scene Description, or USD, can be used for a wide variety of 3D work flows.
