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.
