Overview
ISO/IEC 19777-1:2006 defines the language binding of the Extensible 3D (X3D) abstract interfaces for the ECMAScript programming language. In practical terms, the standard specifies a language-dependent layer that embeds X3D’s abstract interfaces into ECMAScript while obeying the conventions and idioms of that language. It complements the language‑independent API specified in ISO/IEC 19775-2 by providing the ECMAScript-specific mapping needed for implementation and integration.
Key Topics
- Language binding for X3D: Specifies how X3D abstract interfaces are represented and accessed from ECMAScript environments.
- ECMAScript conventions: Requires adherence to ECMAScript naming, object and data type conventions, and runtime behavior when mapping X3D constructs.
- Integration model: Defines the expectations for embedding X3D capabilities into ECMAScript-based applications and runtimes.
- Interoperability with language‑independent API: Works together with ISO/IEC 19775-2 (the language‑independent API) to provide a complete programming model for X3D services.
Note: The standard focuses on the language-dependent mapping and does not replace the language‑independent API; instead it implements that API’s interfaces in ECMAScript.
Applications
ISO/IEC 19777-1:2006 is useful wherever X3D 3D scenes and services need to be controlled from ECMAScript environments:
- Web and browser-based 3D applications using ECMAScript (e.g., web engines and scripting environments).
- Interactive visualization and scientific visualization tools embedding X3D scripting.
- Game engines or simulation frameworks that expose X3D scene control via ECMAScript.
- Tool and library developers implementing X3D runtime bindings for JavaScript/ECMAScript platforms.
- Enterprise and training systems that integrate 3D content with ECMAScript-driven UI logic.
Implementers use this standard to ensure consistent, standards-compliant access to X3D scene graphs and services from ECMAScript code, improving portability and interoperability across platforms.
Related Standards
- ISO/IEC 19775-2 - Defines the language-independent application programmer interface (API) for X3D services and functions; ISO/IEC 19777-1 provides the ECMAScript mapping of those interfaces.
- X3D family and other ISO/IEC graphics standards - use in combination to implement end-to-end 3D solutions.
