Return Value(s)[edit]
- No Return Values for this command.
Description[edit]
- 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)[edit]
- mged> brep obj.brep info F 0
- Output information for the 0th face of obj.brep.
- mged> brep obj.brep plot S 0-2
- Plot the 0th to 2nd surfaces of obj.brep.
- mged> brep sph1.brep intersect sph2.brep 0 0
- Intersect sph1.brep's 0th surface with sph2.brep's 0th surface. (When there's no intersection type specified, we compute SS intersections)
- mged> brep obj.s obj.brep
- Convert implicit primitive obj.s to BREP form named obj.brep.
