Detailed Description
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.
Constructor & Destructor Documentation
| BRepBuilderAPI_GTransform::BRepBuilderAPI_GTransform | ( | const gp_GTrsf & | T | ) |
Constructs a framework for applying the geometric transformation T to a shape. Use the function Perform to define the shape to transform.
| BRepBuilderAPI_GTransform::BRepBuilderAPI_GTransform | ( | const TopoDS_Shape & | S, |
| const gp_GTrsf & | T, | ||
| const Standard_Boolean | Copy = Standard_False |
||
| ) |
Constructs a framework for applying the geometric transformation T to a shape, and applies it 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 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.

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 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: just specify them by calling the function Perform again.
