,
y
point
, and z
point
are real numbers that set the x-, y-, and z-coordinates as the eye-point from
which to view a 3D plot’s view volume. The y-coordinate must always be 1 unit less than the view
volume’s nearest point (y
near
of YVOL). These coordinates are stored in the reserved variable
VPAR.
