A .WRZ file is generally a gzip-compressed VRML world, effectively a .WRL text-based 3D environment—holding geometry, textures, lighting, cameras, and sometimes interactive features—that has been reduced for easier distribution, which is why formats like .WRZ or `.wrl.gz` became common, and the practical way to view it is to unpack it with 7-Zip or `gzip` to obtain a .WRL file readable by VRML-compatible viewers, making sure related texture files stay in the expected folders.

A simple check is seeing whether the file begins with the hex code 1F 8B, which is typical of gzip-compressed data and supports the idea that WRZ is a gzipped WRL, and people often mix it up with RWZ, a format associated with Microsoft Outlook rule settings, so a file from an email setup is probably RWZ, while one from a 3D workflow is almost certainly WRZ.

The phrase “Compressed VRML World” for a .WRZ indicates that it’s a VRML scene file—typically a .WRL, with “WRL” meaning *world*—that has been gzipped to reduce its footprint, because VRML uses structured text to define entire 3D scenes including geometry, materials, textures, lights, and interactive elements, and this text compresses very efficiently, so the VRML ecosystem commonly labels gzipped VRML as .wrl.

From a practical standpoint, the phrase “compressed VRML world” signals that you should open the file as a gzip archive first to recover a .WRL usable in VRML/X3D-capable software, and you can verify this by checking for gzip’s magic bytes 1F 8B in a hex viewer, which is strong evidence you’re dealing with an authentic gzipped VRML file, not a look-alike format.

A VRML “world” (the .WRL obtained after decompressing a .WRZ) generally contains a structured scene graph describing what you see and how you navigate, using Transform/Group nodes for hierarchical transforms, Shape nodes blending geometry—Box—with materials and textures via Material/ImageTexture, plus common extras like Viewpoint camera positions, NavigationInfo navigation rules, and bindable world settings such as Background, Fog, and Sound.

Interactivity in VRML comes from Sensor nodes like contact-based sensors that send events, while animation flows from TimeSensor and assorted interpolators that generate evolving values, connected through ROUTEs tying eventOuts to eventIns, and richer behaviors use Script nodes written in VRMLScript/JavaScript or occasionally Java, plus Anchor nodes for hyperlink-like jumps, with the spec differentiating between nodes affected by transforms and nodes that sit outside the spatial hierarchy—such as interpolators, NavigationInfo, TimeSensor, and Script—making the world behave more like a tiny application than a mere mesh.

Describing .WRZ as a “Compressed VRML World” means it’s not its own format but a VRML world (.WRL) compressed via gzip to reduce bandwidth back in VRML’s web days, so the content remains VRML text defining 3D scene elements like geometry, viewpoints, lights, textures, navigation, and interactivity, with .wrz or .wrl.gz indicating that gzip wrapper—a convention the Library of Congress documents—which is why 7-Zip/gzip works and why spotting the 1F 8B signature early in the file strongly suggests true gzipped VRML.
