  1. What is VRML ? VRML stands for Virtual Reality Modeling Language. VRML is commonly referred to as Vermal. VRML is a simple text language for describing 3-D shapes and interactive environments.

  2. VRML • VRML is a text file where 3D can be specified along with surface color, textures, transparency, and so on. • VRML also allows you to add animations, sounds, lighting, and other aspects of the virtual world. • VRML files are commonly called worlds with .wrl files. • VRML uses four basic shapes Cone, Sphere, Box, and Cylinder.

  3. VRML • When saving VRML files you must save as .wrl (ex. Box.wrl). • When using color is must be typed in diffuseColor 0,0,0. • When using translations you must type them in 0,0,0. The first zero is the x axis, second zero is the y axis, and the third zero is the z axis.

  4. Tools Needed • Editor to create and edit the .wrl file. • Any text editor can be used, but Textpad has useful features. • A Viewer for viewing the 3D world described by the .wrl file. • Textpad VRML Viewer or Web Browser.

  5. Where to get Tools • Download Tools package and Installation Document from Citera website • http://citerawv.us/resources/index.htm • Follow installation document to install VRML Cortona Viewer, Textpad, along with WVHTCF’s custom VRML help tools
