clear3d
and rgl.clear
clear the specified stack, or restore
the defaults for the bounding box (not visible) or viewpoint. By default
with id=0
rgl.pop
removes
the top-most (last added) node on the shape stack. The id
argument
may be used to specify arbitrary item(s) to remove from the specified stack.rgl.clear
and clear3d
may also be used to clear material properties
back to their defaults.
clear3d
has an optional defaults
argument, which defaults to
r3dDefaults
. Only the materials
component of this argument
is currently used by clear3d
.
rgl.ids
returns a dataframe containing the IDs in the currently active
rgl window, along with an indicator of their type.
For convenience, type="shapes"
and
id=1
signifies the bounding box.
Note that clearing the light stack leaves the scene in darkness; it should normally
be followed by a call to rgl.light
or light3d
.
