A .WRZ file is basically a gzip-compressed VRML scene, where a .WRL world file—containing text-based 3D data such as shapes, materials, lights, cameras, and occasional animations—has been reduced in size because VRML compresses extremely well, leading to the convention of naming these archives .WRZ or `.wrl.gz`, and the usual method of opening them is to decompress with something like 7-Zip or `gzip` to produce a .WRL that VRML/X3D tools can read, provided any texture images remain in the correct relative paths.
A straightforward check is verifying whether the file starts with the hex prefix 1F 8B, a strong sign of gzip compression matching the WRZ format, and a common misunderstanding is mixing it up with RWZ, which belongs to email filtering rule backups, so if the file came from email migration it may be RWZ, whereas anything from a 3D or CAD workflow is usually a true WRZ.
Saying a .WRZ is a "Compressed VRML World" means it’s simply a VRML scene—normally saved as .WRL, with "WRL" standing for *world*—that has been gzipped to make the file smaller, as VRML uses structured text to describe full interactive 3D scenes including objects, materials, textures, lighting, and even animations, and since text compresses very efficiently, the VRML community standardized on .wrl. Should you have any kind of inquiries relating to exactly where along with how you can make use of WRZ file viewer software, it is possible to contact us in our own web page. gz or .wrz as names for gzipped VRML files.
Practically speaking, calling it a "compressed VRML world" tells you to handle the file like a gzip stream first so it can expand into a .WRL readable by VRML/X3D-compatible tools, and one easy technical check is whether the file begins with the gzip signature that 1F 8B magic, which strongly indicates you’re dealing with a real gzipped VRML file and not a different format that only looks similar by extension.
Inside the VRML "world" (the .WRL produced after you decompress a .WRZ) you’ll find a typed scene graph covering both scene content and navigation, starting with Transform/Group nodes that define position, rotation, and scale, then Shape nodes that mix geometry—Box—with appearance through Material and ImageTexture, as well as world-level nodes like Viewpoint, NavigationInfo, Background, Fog, or Sound.
In VRML, interactivity stems from Sensor nodes such as TouchSensor that emit events, animations come from TimeSensor and multiple interpolators that generate timed value changes, and ROUTEs wire eventOuts to eventIns, while script nodes using VRMLscript/Javascript (and sometimes Java) add advanced behavior, with Anchor nodes enabling jumps to other worlds or viewpoints, and because VRML separates spatial transform nodes from non-spatial elements like interpolators, NavigationInfo, TimeSensor, and script, the result behaves like a lightweight interactive application rather than a static 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 1F 8B early in the file strongly suggests true gzipped VRML.
