;BOUNDING-BOX cmr

source files: [xc]cmr.[ch]

SYNTAX

(SEND <cmr> :BOUNDING-BOX [:THINGS <thinglist>] [:DEFAULT <default-value>])

DESCRIPTION

This message returns an '((xmin ymin zmin)(xmax ymax zmax)) list bounding the contents of the thinglist. (Which should be nonempty.) The <thinglist> is the usual <thinglist> from :DRAW and :FRAME-THINGS.

If :THINGS is not present explicitly, it should be available as a property on the <cmr> or else the MATRIX44 associated with the <cmr>.

If no points are found, <default-value> is returned if supplied, else an error is signalled.
