RM
dictionary
(Optional;
PDF 1.7)
A
render mode dictionary
that specifies the render mode to
use when rendering 3D artwork with this view (see “3D Render Mode Dictio-
is used.
(Optional;
PDF 1.7)
A
lighting scheme dictionary
that specifies the lighting
scheme to be used when rendering 3D artwork with this view (see “3D Lighting
in the 3D artwork is used.
(Optional;
PDF 1.7)
An array that contains
cross section dictionaries (see
vides parameters for applying a cross section to the 3D artwork when using this
view. An empty array signifies that no cross sections are displayed.
(Optional;
PDF 1.7)
A node array consisting of 3D node dictionaries (see “3D
that change the node’s state, including its opacity and its position in world
space. This entry and the
NR
entry specify how the state of each node is
changed.
If a node dictionary is present more than once, only the last such dictionary
(using a depth-first traversal) is used.
LS
dictionary
SA
array
NA
array
NR
boolean
(Optional;
PDF 1.7)
Specifies whether nodes specified in the
NA
array are re-
turned to their original states (as specified in the 3D artwork) before applying
transformation matrices and opacity settings specified in the node dictionaries.
If
true
, the artwork’s 3D node parameters are restored to their original states
and then the dictionaries specified by the
NA
array are applied. If
false
, the dic-
tionaries specified by the
NA
array are applied to the current states of the nodes.
In addition to the parameters specified by a 3D node dictionary, this flag should
also apply to any runtime parameters used by a viewer application, as well as
any additional parameters specified in future PDF versions.
This value is ignored if the
NA
array is not present.
Default value:
false
For any view, the document author may provide 2D content specific to the view,
to be drawn on top of the 3D artwork. The
O
entry specifies a form XObject that
is overlaid on the rendered 3D artwork. The coordinate system of the form XOb-
ject is defined to be the same as the (x,
y,
0) plane in the camera coordinate sys-
tem (see Section 9.5.4, “Coordinate Systems for 3D”).
