The use of Bezier curves and Bezier triangles has been extensively explored in the field of computer graphics. The purpose of this paper is to show that Bezier triangles and curves can be used for reducing the cost of Biquadratic Phong shading. A shading algorithm has been proposed which uses quadratic Bezier triangle’s blending functions for performing quadratic interpolation of normal vector ...

O. Ismail, Senior Member, IEEE Abstract— Fixed DP curve is a recent representation of the polynomial curves, proposed by Delgado and Pena in 2003. They introduced a new curve representation with linear computational complexity. An algorithmic approach to degree reduction of interval DP curve is presented in this paper. The four fixed Kharitonov's polynomials (four fixed DP curves) associated wi...

Wang-Ball (WB) curve is one of the generalized cubic Ball basis which was first put forward in CONSURF system by Ball. Wang extended it to arbitrary odd and even degrees. An algorithmic approach to degree reduction of interval Wang-Ball curve is presented in this paper. The four fixed Kharitonov's polynomials (four fixed WB curves) associated with the original interval WB curve are obtained. Th...

Fingerprint and Iris are significant biometric tools used for authentication. This paper proposes a novel methodology by which the biometric patterns can be visualized as a set of Bezier curves and hence represented by the corresponding Bezier points, resulting in considerable reduction in the file size. This scheme utilizes the Bezier curve representations for effective compression of all thos...

The creative industries have become the government's attention for contributing to economic accretion. But due lack of artistic creativity and appeal, evolution craft section is not optimal. So that it was needed a variations relief items increase attractiveness. In general, industrial objects design are still limited space geometry or Bezier curve degree two. Therefore, curves selected modifie...

This paper describes the design and implementation of a ROM-Less Direct Digital Frequency Synthesizer (DDS) using Bezier curve approximation. With Bezier curve approximation, phase values between 0 to π are mapped to sine amplitudes. Then, half wave symmetry of sine wave is exploited to construct full sine wave. The proposed approximation introduces maximum error of 7.9×10, which is equivalent ...

Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...

Presented paper describes the method for finding the intersection of class space rational Bezier curves. The problem curve/curve intersection belongs among basic geometric problems and the aim of this article is to describe the new technique to solve the problem using relief perspective and Bezier clipping.
