//! An interface class for 2D fillets.
|
|
//! Open CASCADE provides two algorithms for 2D fillets:
|
|
//! ChFi2d_Builder - it constructs a fillet or chamfer
|
|
//! for linear and circular edges of a face.
|
|
//! ChFi2d_FilletAPI - it encapsulates two algorithms:
|
|
//! ChFi2d_AnaFilletAlgo - analytical constructor of the fillet.
|
|
//! It works only for linear and circular edges,
|
|
//! having a common point.
|
|
//! ChFi2d_FilletAlgo - iteration recursive method constructing
|
|
//! the fillet edge for any type of edges including
|
|
//! ellipses and b-splines.
|
|
//! The edges may even have no common point.
|
|
//!
|
|
//! The algorithms ChFi2d_AnaFilletAlgo and ChFi2d_FilletAlgo may be used directly
|
|
//! or via this ChFi2d_FilletAPI class. This class chooses an appropriate algorithm
|
|
//! analyzing the arguments (a wire or two edges).
