mfrow3d

0th

Percentile

Set up multiple figure layouts in rgl.

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

Keywords
Graphics
Usage
subsceneList(value, window = rgl.cur())

mfrow3d(nr, nc, byrow = TRUE, parent = NA, sharedMouse = FALSE, ...) layout3d(mat, widths = rep.int(1, ncol(mat)), heights = rep.int(1, nrow(mat)), parent = NA, sharedMouse = FALSE, ...) next3d(current = NA, clear = TRUE, reuse = TRUE) clearSubsceneList(delete = currentSubscene3d() %in% subsceneList(), window = rgl.cur())

Arguments
value

A new subscene list to set. If missing, return the current one (or NULL).

window

Which window to operate on.

nr, nc

Number of rows and columns of figures.

byrow

Whether figures progress by row (as with par("mfrow")) or by column (as with par("mfcol")).

mat, widths, heights

Layout parameters; see layout for their interpretation.

parent

The parent subscene. NA indicates the current subscene. See Details below.

sharedMouse

Whether to make all subscenes par3d("listeners") to each other.

Additional parameters to pass to newSubscene3d as each subscene is created.

current

The subscene to move away from. NA indicates the current subscene.

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

If TRUE, delete the subscenes in the current window.

Details

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.

Value

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".
