-package PTopLoc
-
- ---Purpose: The PTopLoc package describes persistent
- -- structures for 3D local coordinate systems.
- --
- -- The class Datum3D describes an elementary local
- -- coordinate system. It is a linear transformation
- -- (Trsf from gp). The transformation is rigid
- -- (Rotation + Translation).
- --
- -- The private class ItemLocation represents an
- -- elementary local coordinate system (Datum3D)
- -- raised to an Integer power elevation. It is used
- -- to link coordinate systems in a Location.
- --
- -- The class Location describes a local coordinate
- -- system. It is a chain of elementary local
- -- coordinate systems raised to power elevations. The
- -- Location keeps track of how the coordinate system
- -- was built.
