VRML (Virtual Reality Modeling Language) is a standard file format for representing 3D interactive vector graphics, designed particularly for the World Wide Web. It allows the creation of "virtual worlds" or 3D scenes that users can explore and interact with. VRML files describe the geometry and appearance of objects in a 3D scene, as well as their behavior and interactions. This includes defining shapes, colors, textures, lighting, and animations. VRML supports features like hyperlinks, allowing objects in the virtual world to link to other VRML scenes or web pages. It also supports scripting languages like JavaScript to add interactivity and dynamic behavior to the scene. VRML was widely used in the late 1990s and early 2000s for creating virtual environments, educational simulations, and interactive 3D content on the web. While largely superseded by X3D and other formats, VRML remains relevant for legacy applications and understanding the history of 3D graphics on the internet. The file format is text-based, making it relatively easy to read and edit, although complex scenes can result in large and intricate files. VRML's open standard nature contributed to its initial popularity, allowing for interoperability between different VRML browsers and authoring tools.
