ISO 14306-2:2024

Overview

ISO 14306-2:2024 is the second part of the international standard defining the JT file format specification for 3D visualization under the scope of industrial automation systems and integration. Published by ISO in August 2024, this document specifically focuses on establishing a comprehensive vocabulary related to the JT file format-a widely used, lightweight, and flexible file format for 3D product definition data.

The ISO 14306 series supports efficient visualization and collaboration across extended enterprises by enabling seamless data streaming, compression, and flexible 3D data repurposing. Part 2, the vocabulary document, serves as a foundational reference for terms and definitions essential to understanding, developing, and implementing the JT file format and related tools and standards.

Key Terms

ISO 14306-2:2024 provides standardized definitions for critical concepts used in the JT file format and 3D visualization, including:

• 3D Visualization: The graphical and textual representation of 3D data to facilitate understanding, information sharing, and decision-making.
• Streaming: Sequential loading of data from disk or over a network to efficiently manage system memory and enable immediate interaction with data.
• Boundary Representation (B-Rep) Solid Model: Defines solid geometry through faces, edges, and vertices bounding the object.
• Logical Scene Graph (LSG): A hierarchical graph representing the logical organization and properties of 3D model components.
• Product and Manufacturing Information (PMI): Non-geometric information such as dimensions, tolerances, symbols, surface finishes, and instructions essential for manufacturing.
• Level of Detail (LOD): Alternate graphical representations of model components to optimize performance.
• Coordinate Systems: Including Local Coordinate System (LCS), Model Coordinate System (MCS), View Coordinate System, and World Coordinate System (WCS), defining how 3D data points are spatially referenced and transformed.
• Shader: Customizable programs determining pixel color based on lighting, texture, and surface attributes.
• Quantize: Process of limiting values to discrete levels rather than continuous sets, improving data precision and compression.
• Collaboration and Extended Enterprise: Terms highlighting cooperative work processes and interconnected entities involved in product lifecycle and delivery.

These terms unify the language used across software developers, engineers, and stakeholders working with JT files, contributing to consistent implementation and interoperability.

Applications

ISO 14306-2:2024 is integral to industries relying on 3D visualization for design, manufacturing, and product lifecycle management, including:

• Industrial Automation: Facilitates exchange and visualization of 3D product data to streamline automation workflows.
• CAD and PLM Systems: Provides a standardized vocabulary for systems supporting JT file handling and visualization.
• Extended Enterprise Collaboration: Enables diverse stakeholders such as suppliers, manufacturers, and customers to share and validate 3D product data efficiently.
• Simulation and Validation: Supports detailed 3D visualization critical for verifying product design and manufacturing information.
• Digital Twins and Virtual Prototyping: Enhances creation and management of virtual representations with consistent terminology and data definitions.

By standardizing vocabulary, this document aids in the development of interoperable software tools and promotes best practices in 3D data management and communication.

Related Standards

ISO 14306-2:2024 is part of the broader ISO 14306 series focused on the JT file format and 3D visualization. It connects with several relevant international standards, such as:

• ISO 14306-1: The core specification covering the general data format and file structure for JT files.
• ISO 10303 (STEP series): Standards for product data representation and exchange relevant for broader CAD and PLM data management.
• ISO 44001: Guidance on collaborative business relationships within extended enterprises, referenced for defining collaboration terminology.
• ISO/IEC 8824-1: Abstract Syntax Notation used for unambiguous information object registration related to this document.
• OpenGL Standards: For graphics programming aspects like texture channels and shaders, as referenced in texture and rendering terms.

These connections help integrate JT format specifications within the global ecosystem of industrial automation and product lifecycle management standards.
