NAME vi - set 3D viewpoint
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
