File created in the HOOPS Stream Format (HSF), a CAD publishing format developed by Tech Soft 3D for visualization; supported via plug-in or as a native publishing format by several CAD applications, including SolidWorks and CATIA v5. OpenHSF has largely been replaced by Adobe's 3D PDF technology, which allows 3D visualization data to be embedded into .PDF documents. The OpenHSF Initiative promoted the HOOPS Stream Format until the PDF visualization technology became available.

The OpenHSF Initiative is an industry-wide effort to establish HOOPS Stream Format (HSF) as a common, open and rich streaming format for sharing visualization data between disparate engineering applications. OpenHSF represents the only truly open visualization format geared specifically toward engineering, making it the ideal solution for sharing visual models between the myriad of applications used within the greater PLM marketplace. Supported by dozens of software vendors and end users and already imported/exported from a wide range of popular applications, OpenHSF is enabling lightweight 2D/3D models to move smoothly through concept, design, analysis, manufacturing, marketing, e-commerce, maintenance and end-of-life phases that make up the full product life-cycle. Membership in the OpenHSF Initiative is free and open to all interested parties. The specification to HSF is public and published and a free version of the HSF read/write SDK is also available to members for use in their applications.
