- shape representation, independent coordinates, B‚zier curve or surface patch, equivalent parameter.
- B‚zier curve is one of typical nonlinear splines, which is of importance for geometric representation, such as edge, contour. Generally, all control points are dealt with based on the same blending functions, regardless of the effect of every independent coordinates on geometric shape. Therefore, current representation lacks flexibility and controllability for complex shape. In this paper, we propose an equivalent parameter representation method using the independent coordinates of control points. Because all control point coordinates are used independently, geometric shape representation becomes more flexible and controllable. Particularly, different geometric shapes can be constructed by the same control points. Modeling experiments show that this proposed method is feasible and reasonable.
