These are considered fields of the node cube. Finally comments are used to make code more easily understood in later use. It can be used at the beginning of a line or at any other point in the line. The Y axis is up and down. Finally, the Z axis is in and out.
All linear measurements are in meters and angle measurements are in radians.
This may be a good time to brush up on degree to radian conversion. These are attributes that must be defined in order to be used. Shapes are hollow. This lesson will teach you how to draw the four basic predefined shapes in VRML without any complications, such as color or light. The four basic shape types in VRML are the cube, the sphere, the cylinder,and the cone.
