MGED CMD bev


bev

Syntax

bev [-t] [-P#] new_obj Boolean_formula


Argument(s)

-t
the resulting object will consist entirely of triangular facets
-P#
specifies the number of CPUs to use for the calculation (however, this is currently ignored).


Return Value(s)

No Return Values for this command.


Description

The "bev" command performs the operations indicated in the Boolean_formula and stores the result in new_obj. The new_obj will be stored as an NMG shape (it may be converted to a by using the nmg_simplify command). If the -t option is specified, then the resulting object will consist entirely of triangular facets. The default is to allow facets of any complexity, including holes. The -P option specifies the number of CPUs to use for the calculation (however, this is currently ignored). Only simple Boolean_formulas are allowed. No parentheses are allowed and the operations are performed from left to right with no precedence. More complex expressions must be expressed as BRL-CAD objects using the r, g, or c commands and evaluated using the facetize or ev commands.


Example(s)

mged> bev -t triangulated_lens sphere1 + sphere2
Create a triangulated object by intersecting objects sphere1 and sphere2.
