this program is a sophisticated
three-dimensional design and display program. Using simple commands,
the user may create a solid object or set of objects in three- dimensional
space, observe, modify, print and store such displays.
The program includes commands to allow you, the user, to move
round the object and look at it from different distances and directions.
In this way, we can design a solid object and obtain a sense of its
reality in the three-dimensional world. After loading VU-3D from cassette,
the user is asked if he wishes to create a new design or set of objects,
or whether he wishes to load a data file from cassette. If this is the
first time you have used VU-3D, press the option "1".
