A `.VRL` file is usually 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.

In a typical VRML/VRL file you’re reading a human-readable scene graph of nodes that outline spatial organization, geometry, and simple behaviors, where objects are positioned with `Transform` nodes, grouped in containers, assigned materials or textures, and reused through `DEF`/`USE` so the same components appear throughout the scene under different transformations to keep the file compact.

In VRML/VRL, visible objects are commonly built with `Shape` nodes combining geometry—such as primitives or `IndexedFaceSet` meshes referencing coordinates and indices—and appearance via `Material` and `ImageTexture`, meaning textures must remain in the expected folders because broken paths cause the geometry to load but display without mapped images, often as plain gray.

VRML files commonly include camera and environmental settings such as `Viewpoint`, `NavigationInfo`, `Background`, and `Fog`, plus lighting nodes like `DirectionalLight`, `PointLight`, or `SpotLight`, which don’t model geometry but shape how the world looks and how users navigate it, and VRML adds interactivity through event-driven nodes like `TimeSensor` and various sensors, with interpolators animating values and `ROUTE` links wiring events so actions like clicks or proximity can trigger movement, rotation, or color changes.

For more sophisticated effects, VRML/VRL supports `Script` nodes that run JavaScript-like code to manage calculations and event handling beyond the reach of basic sensors, while its `Inline` and `PROTO`/`EXTERNPROTO` mechanisms allow pulling in separate VRML files and defining custom node types, making scenes modular and reusable.
