VRML (Virtual Reality Modeling Language) is an open, text-based file format used to describe three-dimensional scenes and objects for interactive 3D graphics applications and virtual reality environments. VRML files define the geometry, appearance, lighting, and interactivity of 3D scenes, allowing them to be rendered and explored in real-time using compatible VRML viewers and browsers.

Key features of VRML include:

Scene Description: VRML files describe the structure of a 3D scene, including objects, their positions, orientations, scales, colors, and textures.

Hierarchy: VRML scenes can have a hierarchical structure with parent-child relationships between objects, allowing for complex scene organization.

Geometry and Appearance: VRML supports basic geometric shapes (cubes, spheres, cones, etc.) and provides options for applying textures, materials, and lighting to objects.

Interactivity: VRML supports interactivity through scripting, allowing users to interact with and manipulate objects within the scene.

Animation: VRML supports animations, including the ability to animate object transformations and properties over time.

Navigation: VRML scenes can include navigation information, enabling users to move through and explore the virtual environment.

File Format: VRML files are typically saved with the .wrl file extension. The format uses a text-based syntax that is human-readable and editable.

Compatibility: VRML was designed to be platform-independent and can be viewed in VRML-enabled browsers, standalone viewers, and 3D modeling software.

Integration: VRML can be integrated with web pages to create interactive 3D content for websites.

VRML was developed in the 1990s and gained popularity as one of the early standards for creating interactive 3D content for the web. However, its adoption diminished over time as newer technologies and formats emerged, such as X3D (an evolution of VRML) and more modern web technologies like WebGL.

X3D is a successor to VRML and extends its capabilities to support advanced features and better integration with modern web standards. WebGL, a JavaScript API, enables hardware-accelerated 3D graphics in web browsers without the need for plug-ins.

If you're working with 3D content for the web, consider exploring X3D and WebGL as potential alternatives to VRML, as they offer improved performance, better compatibility, and integration with contemporary web technologies.
