A `.VRL` file is typically a VRML scene file containing human-readable text that outlines 3D objects and materials, and the fastest check is opening it in a text editor to look for the `#VRML V2.0 utf8` header or familiar keywords like `Transform` and `Material`, since some workflows save VRML as `.vrl` rather than `.wrl`, and once confirmed you can load it in a VRML/X3D viewer or Blender for conversion, keeping texture folders intact to avoid missing-texture problems, while a file that appears as binary noise may indicate compression or a proprietary format best identified by 7-Zip or its source.

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.

A VRML/VRL file shows its visual elements through `Shape` nodes that merge geometry and appearance, using primitives or mesh types like `IndexedFaceSet` defined by coordinate data and index lists, and surface style comes from `Material` values or texture references in `ImageTexture`, so losing the referenced image files leads to a flat gray look even though the model itself still loads.

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 may include `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.
