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.

  • 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.


Tools needed
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.
