class Transform from BRepBuilderAPI inherits ModifyShape from BRepBuilderAPI
|
|
|
|
---Purpose: Geometric transformation on a shape.
|
|
-- The transformation to be applied is defined as a
|
|
-- gp_Trsf transformation, i.e. a transformation which does
|
|
-- not modify the underlying geometry of shapes.
|
|
-- The transformation is applied to:
|
|
-- - all curves which support edges of a shape, and
|
|
-- - all surfaces which support its faces.
|
|
-- A Transform object provides a framework for:
|
|
-- - defining the geometric transformation to be applied,
|
|
-- - implementing the transformation algorithm, and
|
|
-- - consulting the results.

returns Transform from BRepBuilderAPI;
|
|
---Purpose: Constructs a framework for applying the geometric
|
|
-- transformation T to a shape. Use the function Perform
|
|
-- to define the shape to transform.

returns Transform from BRepBuilderAPI;
|
|
---Purpose: Creates a transformation from the gp_Trsf <T>, and
|
|
-- applies it to the shape <S>. If the transformation
|
|
-- is direct and isometric (determinant = 1) and
|
|
-- <Copy> = Standard_False, the resulting shape is
|
|
-- <S> on which a new location has been set.
|
|
-- Otherwise, the transformation is applied on a
|
|
-- duplication of <S>.

|
|
|
|
---Purpose: pplies the geometric transformation defined at the
|
|
-- time of construction of this framework to the shape S.
|
|
-- - If the transformation T is direct and isometric, in
|
|
-- other words, if the determinant of the vectorial part
|
|
-- of T is equal to 1., and if Copy equals false (the
|
|
-- 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: this framework can be reused to apply the same
|
|
-- geometric transformation to other shapes. You only
|
|
-- need to specify them by calling the function Perform again.
