TopLoc_Datum3D Class Reference

Describes a coordinate transformation, i.e. a change to an elementary 3D coordinate system, or position in 3D space. A Datum3D is always described relative to the default datum. The default datum is described relative to itself: its origin is (0,0,0), and its axes are (1,0,0) (0,1,0) (0,0,1). More...

Detailed Description

Describes a coordinate transformation, i.e. a change to an elementary 3D coordinate system, or position in 3D space. A Datum3D is always described relative to the default datum. The default datum is described relative to itself: its origin is (0,0,0), and its axes are (1,0,0) (0,1,0) (0,0,1).

Constructor & Destructor Documentation

◆ TopLoc_Datum3D() [1/2]

TopLoc_Datum3D::TopLoc_Datum3D ( )

Constructs a default Datum3D.

◆ TopLoc_Datum3D() [2/2]

TopLoc_Datum3D::TopLoc_Datum3D ( const gp_Trsf T)

Constructs a Datum3D form a Trsf from gp. An error is raised if the Trsf is not a rigid transformation.

Member Function Documentation

◆ ShallowDump()

void TopLoc_Datum3D::ShallowDump ( Standard_OStream S) const

Writes the contents of this Datum3D to the stream S.

◆ Transformation()

const gp_Trsf& TopLoc_Datum3D::Transformation ( ) const

Returns a gp_Trsf which, when applied to this datum, produces the default datum.
