SYNOPSIS

vi

vi [x|. y|. z|.]

vi radius

DESCRIPTION

The vi command sets the 3D mode view point, which determines the perspective of the 3D plot. The view point is the position in space from where you view the center of the 3D box. The units of the view point are in the box units used with the bo command. Those units place one corner of the 3D box at (0, 0, 0) and the opposite corner at the position set by the bo command. The default view point is at (1.3, -2.4, 2).

To set the view point, you can enter the coordinates as arguments to the command, or you can just enter vi and be prompted for values. When entering arguments on the command line, you can enter a dot to indicate you want to use the current value for the particular coordinate.

By giving one numerical argument to the vi command you can change the view distance without changing the view direction.

EXAMPLE

vi 1.3 -2.4 2
