class GTransform from BRepBuilderAPI inherits ModifyShape from BRepBuilderAPI
|
|
|
|
---Purpose: Geometric transformation on a shape.
|
|
-- The transformation to be applied is defined as a gp_GTrsf
|
|
-- transformation. It may be:
|
|
-- - a transformation equivalent to a gp_Trsf transformation, the
|
|
-- most common case: you should , however, use a BRepAPI_Transform
|
|
-- object to perform this kind of transformation; or
|
|
-- - an affinity, or
|
|
-- - more generally, any type of point transformation which may
|
|
-- be defined by a three row, four column matrix of transformation.
|
|
-- In the last two cases, the underlying geometry of the
|
|
-- following shapes may change:
|
|
-- - a curve which supports an edge of the shape, or
|
|
-- - a surface which supports a face of the shape;
|
|
-- For example, a circle may be transformed into an ellipse when
|
|
-- applying an affinity transformation.
|
|
-- The transformation is applied to:
|
|
-- - all the curves which support edges of the shape, and
|
|
-- - all the surfaces which support faces of the shape.
|
|
-- A GTransform object provides a framework for:
|
|
-- - defining the geometric transformation to be applied,
|
|
-- - implementing the transformation algorithm, and
|
|
-- - consulting the result.

---Purpose: Constructs a framework for applying the geometric

|
|
-- - If the transformation T is direct and isometric (i.e. if
|
|
-- the determinant of the vectorial part of T is equal to
|
|
-- 1.), and if Copy equals false (default value), the
|
|
-- resulting shape is the same as the original but with
|
|
-- a new location assigned to it.
|
|
-- - In all other cases, the transformation is applied to
|
|
-- a duplicate of S.
|
|
-- Use the function Shape to access the result.
|
|
-- Note: the constructed framework can be reused to
|
|
-- apply the same geometric transformation to other
|
|
-- shapes: just specify them with the function Perform.

---Purpose: Applies the geometric transformation defined at the

-- time of construction of this framework to the shape S.
|
|
-- - If the transformation T is direct and isometric (i.e. if

-- the determinant of the vectorial part of T is equal to

-- 1.), and if Copy equals false (default value), the

-- resulting shape is the same as the original but with
