BndLib Class Reference

The BndLib package provides functions to add a geometric primitive to a bounding box. Note: these functions work with gp objects, optionally limited by parameter values. If the curves and surfaces provided by the gp package are not explicitly parameterized, they still have an implicit parameterization, similar to that which they infer for the equivalent Geom or Geom2d objects. Add : Package to compute the bounding boxes for elementary objects from gp in 2d and 3d . More...

## Detailed Description

The BndLib package provides functions to add a geometric primitive to a bounding box. Note: these functions work with gp objects, optionally limited by parameter values. If the curves and surfaces provided by the gp package are not explicitly parameterized, they still have an implicit parameterization, similar to that which they infer for the equivalent Geom or Geom2d objects. Add : Package to compute the bounding boxes for elementary objects from gp in 2d and 3d .

AddCurve2d : A class to compute the bounding box for a curve in 2d dimensions ;the curve is defined by a tool

AddCurve : A class to compute the bounding box for a curve in 3d dimensions ;the curve is defined by a tool

AddSurface : A class to compute the bounding box for a surface. The surface is defined by a tool for the geometry and another tool for the topology (only the edges in 2d dimensions)
