grotate(z, y, x) |
| See Also | mesh |
z, y, and x
plotting axis by the specified number of degrees,
where x, y, and z are
integer, real, or double-precision scalars.
Before the rotation, the positive x direction is to the right,
the positive y direction is up,
and the positive z direction comes out of the screen.
(The direction of rotation is
clockwise when looking down the corresponding axis from its positive side.)

grotate(30, 0, 70)

gytitle("y")
gztitle("z")
The first rotation is 30 degrees about the positive z direction.
This leaves the positive z direction fixed,
makes the positive x direction down and to the right,
and makes the positive y direction up and to the right.
y direction
has no effect.
x direction
(which is now down and to the right)
leaves the positive z direction up and out of the screen,
the positive y direction to the right, up, and into the screen,
and the positive x direction as it was, down and to the right in
the plane of the screen.
