A `.VRL` file is most often a VRML world file written in plain text that describes a 3D scene much like HTML describes a webpage, and you can confirm this by opening it in a text editor to check for a `#VRML V2.0 utf8` header and keywords such as `Transform`, `Shape`, or `IndexedFaceSet`, since some tools use `.vrl` instead of `.wrl`, and once identified you can view it with a VRML/X3D viewer, edit it in Blender, and avoid display issues by keeping textures in the same folder, while a binary-looking file may mean it’s compressed or not VRML at all, in which case 7-Zip or the file’s origin usually provides the clue.
Inside a VRML/VRL file you’re essentially reading a text-based scene graph made of nodes that describe what exists in 3D space and how it’s arranged, with structural nodes organizing objects, visual nodes drawing geometry, and other nodes shaping navigation or interaction, and because it’s plain text you can usually see objects placed, transformed, and textured, often wrapped in `Transform` groups and reused through `DEF`/`USE` so the same geometry appears multiple times with different placements.
The visible content in VRML/VRL files is commonly produced by `Shape` nodes that pair geometry with appearance, where geometry may be primitives like `Box` or `Sphere` or complex meshes such as `IndexedFaceSet` that rely on coordinate lists and index arrays, and appearances use `Material` and `ImageTexture` nodes to define color, shininess, or textures—meaning texture folders must stay nearby or the model loads as dull gray.
In VRML you’ll often find world-level elements including `Viewpoint`, `NavigationInfo`, `Background`, `Fog`, and different light types, which influence the camera and mood rather than modeling objects, and the format’s interactive side uses timers, sensors, and interpolators—connected by `ROUTE` statements—to let events such as clicks, motion, or time-based triggers animate objects or adjust properties on the fly.

When simple sensors aren’t enough, VRML/VRL can embed `Script` nodes using ECMAScript-like code to handle complex interactions or dynamic values, and through `Inline` imports plus `PROTO`/`EXTERNPROTO` extensions, creators can organize scenes across multiple files and custom components instead of maintaining a single unwieldy model.
