Argument(s)

object

Name for the primitive that you want to operate on.

S

Plot or output info for a specific 'surface'.

F

Plot or output info for a specific 'face'.

T

Plot or output info for a specific 'trim'.

E

Plot or output info for a specific 'edge'.

SB

Output 'bezier' info for a specific 'surface'.

TB

Output 'bezier' info for a specific 'trim'.

I

Plot a specific 'iso-surface'.

SN

Plot a specific 'surface normal'.

KN

Plot a specific 'surface's knots'.

F2d

Plot a specific 'face' in '2d-space'.

SBB

Plot a specific 'surface's leafs' (surface tree).

SBB2d

Plot a specific 'surface's leafs' in '2d-space'.

TD

Plot a specific 'trim direction'.

T2d

Plot a specific 'trim' in '2d-space'.

TBB

Plot a specific 'trim's leafs' (curve tree).

TBB2d

Plot a specific 'trim's leafs' in '2d-space'.

SCV

Plot a specific 'surface's CV'.

index

The index of the surface (face, edge, etc.) you want to plot or output info for. You can use a single number, 'number-number', or 'all'.

object2

The other object to intersect 'object'.

i

Intersect object's ith surface.

j

Intersect object2's jth surface.

max_dis

A number to control the output intersection curves.

brepname

When convert a non-BREP object to BREP, the result BREP's name.

comb

suffix

Return Value(s)

No Return Values for this command.

Description

The "brep" command is a command for debugging the NURBS (BREP) functionality in BRL-CAD. It can output info information for a specific object, plot its surfaces, faces, etc., and test the implicit to NURBS conversion and surface-surface intersection functionality.

Example(s)

mged> facetize region1.nmg region1.r

Create a facetized BOT version of existing object region1.r.
