A `.VRL` file is mostly a VRML world file written in text to define 3D objects and their materials, which you can check by viewing it in a text editor for the `#VRML V2.

A VRML/VRL file works like a text description of a 3D scene graph made up of nodes that define structure, geometry, and behavior, letting you read how objects are positioned, rotated, textured, and grouped, with `Transform` nodes setting spatial properties and `DEF`/`USE` letting the file reuse pieces such as repeating shapes or materials so large scenes are built efficiently through shared references.

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.

A VRML file often sets up global elements such as viewpoints, navigation styles, background visuals, fog intensity, and lights, which shape how a viewer experiences the scene, and VRML’s event system uses sensors, timers, and interpolators wired through `ROUTE` so user actions or timed triggers can animate movement, rotation, or color transitions.

When richer logic is needed, VRML/VRL files can leverage `Script` nodes containing ECMAScript-style code to process events or coordinate intricate interactions, and the format’s modularity features—`Inline` for external files and `PROTO`/`EXTERNPROTO` for custom node types—let scenes be structured from multiple reusable parts.
