VRML, or Virtual Reality Modeling Language, is a standard file format used to create and display 3D interactive graphics on the web. Developed in the mid-1990s, it allows users to navigate through virtual environments and interact with 3D objects using a web browser. VRML files are text-based and describe the geometry, appearance, and behavior of 3D scenes. They can include various elements like shapes, colors, and animations, making it possible to create immersive experiences. Although it has been largely replaced by more advanced technologies like WebGL and Unity, VRML laid the groundwork for 3D web content.
