Subject: 12. PRIMITIVE SHAPES

-------------------------------------------------------------------

TIME: Complete this section within 15 minutes

-------------------------------------------------------------------



Most 3D languages have a collection of built-in shapes, or primitives,

that are referenced by name (as opposed to requiring you to create them

yourself they are already there -- just reference them by name).



VRML supports the following primitive nodes:



 Box

 Cone

 Cylinder

 Sphere



You can set the "fields" for nodes to change how the node looks or acts.

To see the fields that these nodes support view the "6 Node reference"

section of the VRML97 Specification.



For fun: Change the fields of your simple.wrl primitive shapes, save the

file, then open (or reload) it in your browser.
