A .WRZ file represents a gzipped VRML world, where a .WRL 3D scene—built from plain-text instructions describing geometry, materials, textures, lights, and occasional animations—has been gzip-packed for easier sharing, which resulted in the convention of calling such files .WRZ or `.wrl.gz`, and the usual approach is to unzip them with tools like 7-Zip or `gzip` to obtain a .WRL file that VRML-supporting viewers can load, with textures appearing correctly only if their referenced image files stay in the proper folders.

A straightforward check is verifying whether the file starts with the gzip indicator 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 Microsoft Outlook rule configurations, 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 wrapped in gzip 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.

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 the standard 1F 8B header in a hex viewer, which is strong evidence you’re dealing with an authentic gzipped VRML file, not a look-alike format.

Exploring a VRML "world" (the .WRL you get from unpacking a .WRZ) shows a scene graph of typed nodes describing visuals and user movement, with Transform/Group constructs managing transform hierarchies, Shape nodes merging geometry such as Sphere with Material/ImageTexture appearance, and standard world components including Viewpoint cameras, NavigationInfo behavior settings, and bindable environment nodes like Background, optional Fog, and Sound.

A VRML world handles interaction through Sensor nodes such as ProximitySensor that fire events, while animations rely on TimeSensor plus the various interpolators (Position/Orientation/Color/Scalar) to produce timed value changes, all linked together via ROUTE connections, and advanced logic is added through Script nodes using VRMLScript/JavaScript or, in some cases, Java, with Anchor nodes enabling hyperlink-style navigation, and VRML distinguishes spatial nodes in the transform tree from non-spatial nodes like interpolators, NavigationInfo, TimeSensor, and Script, giving the world an interactive program-like feel.

A .WRZ being a "Compressed VRML World" means WRZ is just a VRML .WRL file wrapped in gzip for smaller transfers, keeping VRML’s text-based description of meshes, textures, lighting, viewpoints, navigation settings, and simple interactions intact, but delivered in gzip form and named .wrz or .wrl.gz as noted by the Library of Congress; this is why decompression tools like 7-Zip/gzip open it easily, and why the gzip magic bytes 1F 8B in the header help confirm it’s authentic gzipped VRML rather than an unrelated format.
