Virtual Reality model
WRL is a file extension for a Virtual Reality Modeling Language (VRML) file format often used by browser plug-ins to display virtual reality environments. VRML files are known as “worlds,” which is what WRL stands for.
WRL files are plain ASCII text files. A WRL file includes data specifying 3-D details such as vertices, edges for a 3-D polygon, surface color, image-mapped textures, light and reflection mapping, and transparency.
MIME type: x-world/x-vrml, model/vrml
