The mfrow3d
and layout3d
functions provide functionality in rgl
similar to par("mfrow")
and layout
in classic R graphics.

value |
A new subscene list to set. If missing, return the current one (or |
window |
Which window to operate on. |
nr, nc |
Number of rows and columns of figures. |
byrow |
Whether figures progress by row (as with |
mat, widths, heights |
Layout parameters; see |
parent |
The parent subscene. |
sharedMouse |
Whether to make all subscenes |
... |
Additional parameters to pass to |
current |
The subscene to move away from. |
clear |
Whether the newly entered subscene should be cleared upon entry. |
reuse |
Whether to skip advancing if the current subscene has no objects in it. |
delete |

rgl can maintain a list of subscenes; the mfrow3d
and layout3d
functions create that list.
When the list is in place, next3d
causes rgl to move to the next scene in the list, or cycle
back to the first one.
Unlike the classic R graphics versions of these functions, these functions are completely compatible with each other. You can mix them within a single rgl window.
In the default case where parent
is missing, mfrow3d
and layout3d
will
call clearSubsceneList()
at the start.
By default clearSubsceneList()
checks
whether the current subscene is in the current subscene list; if so, it will delete
all subscenes in the list, and call gc3d
to delete any objects that are no
longer shown. The subscene list will be set to a previous value if one was recorded,
or NULL
if not.
If parent
is specified in mfrow3d
or layout3d
(even as NA
), the new subscenes will be created within
the parent.
The next3d()
function first finds out if the current
subscene is in the current list. If not, it moves to the
previous list, and looks there. Once it finds a list
containing the current subscene, it moves to the next entry
in that list. If it can't find one, it creates a length
one list containing just the current subscene.
mfrow3d
and layout3d
return a vector of subscene id values that have just been
created. If a previous subscene list was in effect and was not automatically cleared,
it is attached as an attribute "prev"
.
