ISO/DIS 14306-3

Industrial automation systems and integration — JT file format specification for 3D visualization — Part 3: Version 2

Scope

The JT file format specification for 3D visualization specifies the sequential order of bytes that comprise the segments of data required to represent an ISO 14306 file. The JT format is uniquely compressed to minimize file size.
The JT file format specification for 3D visualization includes data descriptions that can represent the following data.
— facet information (triangles), stored with geometry compression techniques;
— visual attributes such as lights, textures and materials;
— product manufacturing information (PMI);
— boundary representation (b-rep) solid model shape representation and associated metadata;
— configuration representations; and
— delivery methods such as asynchronous streaming of content.

The JT file format specification for 3D visualization does not specify the implementation of, or definition of, any runtime architecture for viewing and/or processing ISO 14306 data.
