How to convert X_T
to VRML?

A file with extension X_T (Parasolid text files) is used by the Parasolid core created by Siemens PLM Software. It is being developed as a standard export format for distributing Parasolid CAD models.

The X_T file is a set of structured data containing information about the features of the model construction, the topology of its structural elements, color scheme, coordinates of drawing primitives, etc.

The X_T extension is unpretentious to adapt and can be exported / imported for use in a wide variety of CAD systems. It is stored in text format and can be exported and imported using a variety of other computer-aided design programs.

X_T files are used instead of the old version of the XMT_TXT and XMP_TXT files, which are less used than X_B (Parasolid binary files), and store the same data, but in binary format.

VRML (Virtual Reality Modeling Language) was originally known before 1995 as the Virtual Reality Markup Language. It is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind.

VRML is a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color, UV mapped textures, shininess, transparency, and so on. URLs can be associated with graphical components so that a web browser might fetch a webpage or a new VRML file from the Internet when the user clicks on the specific graphical component. Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. A special Script Node allows the addition of program code (e.g., written in Java or ECMAScript) to a VRML file.

VRML files are commonly called "worlds" and have the *.wrl extension (for example island.wrl). VRML files are in plain text and generally compress well using gzip, useful for transferring over the internet more quickly (some gzip compressed files use the *.wrz extension). Many 3D modeling programs can save objects and scenes in VRML format.
