Learn how to convert VRML to GLB with CAD Exchanger
VRML (Virtual Reality Modeling Language) was originally known before 1995 as the Virtual Reality Markup Language. It is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind.
VRML is a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color, UV mapped textures, shininess, transparency, and so on. URLs can be associated with graphical components so that a web browser might fetch a webpage or a new VRML file from the Internet when the user clicks on the specific graphical component. Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. A special Script Node allows the addition of program code (e.g., written in Java or ECMAScript) to a VRML file.
VRML files are commonly called "worlds" and have the *.wrl extension (for example island.wrl). VRML files are in plain text and generally compress well using gzip, useful for transferring over the internet more quickly (some gzip compressed files use the *.wrz extension). Many 3D modeling programs can save objects and scenes in VRML format.
Supporting data such as 3D scenes, models, lighting, materials, and geometry / animation are all stored in a single GLB file, eliminating the need for extra support files to access textures, geometry, shaders, animation, and other types of data required for a 3D view. GLB files are 30% smaller than glTF and its associated files, so they load and process faster.
GLB is compatible with various 3D visualization programs, such as Microsoft Paint 3D, Microsoft Remix 3D, Blender, Trimble 3D Warehouse, SketchUp.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
