Like VRML? https://en.wikipedia.org/wiki/Vrml https://en.wikipedia.org/wiki/Vrml > VRML (Virtual Reality Modeling Language, pronounced vermal or by its initials, originally—before 1995—known as the Virtual Reality Markup Language) is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. It has been superseded by X3D. https://en.wikipedia.org/wiki/X3D https://en.wikipedia.org/wiki/X3D X3D is a royalty-free ISO/IEC standard for declaratively representing 3D computer graphics. File format support includes XML, ClassicVRML, Compressed Binary Encoding (CBE) and a draft JSON encoding. X3D became the successor to the Virtual Reality Modeling Language (VRML) in 2001.[1] X3D features extensions to VRML (e.g. CAD, geospatial, humanoid animation, NURBS, etc.), the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, or binary formatting, and enhanced APIs. There's also OpenXR: https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspe...
