Coordinate System Representation Item

group a3d_ricoordinatesystem

An axis system.

An A3DRiCoordinateSystem is an A3DRiRepresentationItem that specifies a coordinate system. The A3DRiCoordinateSystemData structure contains an A3DMiscCartesianTransformation axis system. This axis system owns the geometric data: there is no particular geometry attached, and the user is responsible for representation.

Note

An A3DRiCoordinateSystem is an A3DRiRepresentationItem and not an A3DMiscCartesianTransformation. Being a representation item, a coordinate system can own a local coordinate system (on the RI level), which can also own a local coordinate system, and so on…

`A3DRiCoordinateSystemGet()`	Populates the A3DRiCoordinateSystemData structure.
`A3DRiCoordinateSystemCreate()`	Creates an A3DRiCoordinateSystem from an A3DRiCoordinateSystemData structure.
`A3DRiCoordinateSystemEdit()`	Modifies an A3DRiCoordinateSystem from an A3DRiCoordinateSystemData structure.
