[edit] Syntax

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

[edit] 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).

[edit] Return Value(s)

No Return Values for this command.

[edit] 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.

[edit] Example(s)

mged> bev -t triangulated_lens sphere1 + sphere2

Create a triangulated object by intersecting objects sphere1 and sphere2.

"Prohibition...goes beyond the bounds of reason in that it attempts to control a man's appetite by legislation and makes a crime out of things that are not crimes. A prohibition law strikes a blow at the very principles upon which our government was founded." - Abraham Lincoln, 1840
