A `.VRL` file is frequently a VRML scene file describing 3D environments in readable text, and you can confirm its type by opening it in a text editor and checking for `#VRML V2.

When you open a VRML/VRL file you’re looking at a text-driven scene graph built from nodes that specify how a 3D world is organized, drawn, and interacted with, and you can usually follow the intended layout as objects are placed and given materials inside `Transform` groups, with repeated items linked through `DEF` and `USE` to keep the scene lightweight while reusing the same geometry in multiple spots.
The “things you see” in a VRML/VRL file are typically defined by `Shape` nodes that merge geometry and appearance, where geometry may be basic shapes or `IndexedFaceSet` meshes driven by coordinate and index arrays, and surface style is set through `Material` settings and optional textures, which rely on file paths that must stay intact or the model loses its mapped images and appears gray.
In VRML you’ll frequently 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.
For more advanced behavior, a VRML/VRL file often adds `Script` nodes that run ECMAScript-style code to compute values, respond to events, or manage interactions too complex for sensors and interpolators alone, and the format supports modularity through `Inline` nodes plus extensibility via `PROTO`/`EXTERNPROTO`, allowing scenes to be built from external pieces and custom node types instead of one huge file.
