class MakeTransformed from StepToTopoDS inherits Root
---Purpose : Produces instances by Transformation of a basic item
uses Trsf from gp, Shape from TopoDS,
TransientProcess from Transfer,
Axis2Placement3d from StepGeom,
CartesianTransformationOperator3d from StepGeom,
MappedItem from StepRepr
is
Create returns MakeTransformed;
Compute (me : in out; Origin, Target : Axis2Placement3d from StepGeom)
returns Boolean;
---Purpose : Computes a transformation to pass from an Origin placement to
-- a Target placement. Returns True when done
-- If not done, the transformation will by Identity
Compute (me : in out; Operator : CartesianTransformationOperator3d from StepGeom) returns Boolean;
---Purpose : Computes a transformation defined by an operator 3D
Transformation (me) returns Trsf from gp;
---Purpose : Returns the computed transformation (Identity if not yet or
-- if failed)
---C++ : return const &
Transform (me; shape : in out Shape from TopoDS) returns Boolean;
---Purpose : Applies the computed transformation to a shape
-- Returns False if the transformation is Identity
TranslateMappedItem (me : in out; mapit : MappedItem from StepRepr;
TP : mutable TransientProcess from Transfer)
returns Shape;
---Purpose : Translates a MappedItem. More precisely
-- A MappedItem has a MappingSource and a MappingTarget
-- MappingSource has a MappedRepresentation and a MappingOrigin
-- MappedRepresentation is the basic item to be instanced
-- MappingOrigin is the starting placement
-- MappingTarget is the final placement
--
-- Hence, the transformation from MappingOrigin and MappingTarget
-- is computed, the MappedRepr. is converted to a Shape, then
-- transformed as an instance of this Shape
