JT (visualization format)
3D data format
JT (Jupiter Tessellation) is an openly-published ISO-standardized 3D CAD data exchange format used for product visualization, collaboration, digital mockups, and other purposes. It was developed by Siemens.
It can contain any combination of approximate (faceted) data, boundary representation surfaces (NURBS), Product and Manufacturing Information (PMI), and Metadata (textual attributes) either exported from the native CAD system or inserted by a product data management (PDM) system.
The JT format contains a scene graph representation of an assembly, nested sub-assemblies of parts with CAD specific node and attributes data. Facet information (triangles) is stored by using geometry compression techniques. Visual attributes of 3D scene and model like lights, textures, and/or materials are supported. Product and Manufacturing Information (PMI), Precise Part definitions (BRep), additional metadata, and a variety of representation configurations are supported. The JT format is designed to be streamable.
Overview
JT files are used in product lifecycle management (PLM) software programs and their respective CAD systems, by engineers and other professionals that need to analyze the geometry of complex products. The format and associated software is structured so that extremely large numbers of components can be quickly loaded, shaded and manipulated in real-time.
“JT (visualization format)” enters the record as 3D data format. Crown Archives preserves that source wording while asking what visualization, format and data can confirm, complicate or overturn.
Why this record matters
“JT (visualization format)” is worth following because a concise public description often conceals a longer documentary argument. Here, visualization, format and data provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q1589482. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
