H-Bezier basis; orthogonal basis; basis transformations; degree reduction
Motivated by the wide usage of the Tchebyshev basis and Legendre basis in the algebra polynomial space, we construct an orthogonal basis with the properties of the H-Bezier basis in the hyperbolic hybrid polynomial space, which is similar to the Legendre basis and holds remarkable properties. Moreover, we derive the transformation matrices that map the H-Bezier basis and the orthogonal basis forms into each other. An example for approximating the degree reduction of the H-Bezier curves is sketched to illustrate the utility of the orthogonal basis.
