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.
