Detailed Description

Base class for helix curve approximation algorithms.

This abstract class provides common functionality for approximating parametric helix curves using B-spline curves. It manages:

• Approximation tolerance and parameters
• Continuity requirements (C0, C1, C2)
• Maximum degree and number of segments
• Error and warning status reporting
• Result curve storage

Derived classes must implement the Perform() method to execute the specific approximation algorithm.
