| | The GeomConvert package provides some global functions as follows
- converting classical Geom curves into BSpline curves,
- segmenting BSpline curves, particularly at knots
values: this function may be used in conjunction with the
GeomConvert_BSplineCurveKnotSplitting
class to segment a BSpline curve into arcs which
comply with required continuity levels,
- converting classical Geom surfaces into BSpline surfaces, and
- segmenting BSpline surfaces, particularly at
knots values: this function may be used in conjunction with the
GeomConvert_BSplineSurfaceKnotSplitting
class to segment a BSpline surface into patches
which comply with required continuity levels.
All geometric entities used in this package are bounded.
