//! 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.
