- •
A new composite representation method is proposed for surface approximation.
- •
The results do not rely on basis functions with the parameterization optimization.
- •
Non-smooth features are fitted well even with smooth polynomial basis functions.
- •
An augmented Lagrange method based numerical algorithm is presented.
