KEY
TYPE
VALUE
C
array
(Optional)
A three element array specifying the center of rotation on the cutting plane
in world space coordinates (see Section 9.5.4, “Coordinate Systems for 3D).
Default value:
[0 0 0]
specifying a cutting plane rotating about the origin of the world
space.
O
array
(Required)
A three-element array specifying the orientation of the cutting plane in
world space, where each value represents the orientation in relation to the X, Y, and Z
axes, respectively (see Section 9.5.4, “Coordinate Systems for 3D). Exactly one of the
values must be
null
, indicating an initial state of the cutting plane that is perpendicular
to the corresponding axis and clipping all geometry on the positive side of that axis.
The other two values must be numbers indicating the rotation of the plane, in degrees,
around their corresponding axes. The order in which these rotations are applied
should match the order in which the values appear in the array.
Default value:
[null 0 0]
specifying a cutting plane that is perpendicular to the X axis
and coplanar with the Y and Z axes.
PO
number
(Optional)
A number in the range [0, 1] indicating the opacity of the cutting plane us-
ing a standard additive blend mode.
Default value: 0.5
PC
array
(Optional)
An array that specifies the color for the cutting plane. The first entry in the
array is a color space, and the remaining entries are values in that color space. The
only valid color space is
DeviceRGB
. If a color space other than
DeviceRGB
is specified,
this entry is ignored and the default value is used.
Default value:
[/DeviceRGB 1 1 1
] representing the color white.
IV
boolean
(Optional)
A flag indicating the visibility of the intersection of the cutting plane with
any 3D geometry. If
true
, then the intersection is visible. If
false
, then the intersection
is not visible.
Default value:
false
IC
array
(Optional)
An array that specifies the color for the cutting plane’s intersection with the
3D artwork. The first entry in the array is a color space, and the remaining entries are
values in that color space. The only valid color space is
DeviceRGB
. If a color space
other than
DeviceRGB
is specified, this entry is ignored and the default value is used.
This entry is meaningful only if
IV
is
true
.
Default value: [
/DeviceRGB 0 1 0
] representing the color green.
