A Modified BEZIER Algorithm For Controlling and Generating A Third Degree Curves
نویسنده
چکیده
This paper presents a new method to generate curves, which allows the designer to produce a curve in combinational way allowing him to get the shape that he had in his imagination with keeping the four control point for the curve design. Basing on the modified BEZIER curve, the upgraded algorithm used de Casteljau algorithm on interval [r, s] as a mathematical base to upgrade the suggested method. The suggested method shows a great flexibility at the curve controlling area with changing one, more or no need to change the control points of Bezier curve as it shows in the figures presented in the paper. ریوطت ةیمزراوخ ) BEZIER ( ةثلاثلا ةجردلا نم تاینحنملأ دیلوتو مكحتلل ةصلاخلا هریو طتو ي نحنملا د یلوت مم صملل حی تی يذ لاو تاینحنملا دیلوتل ادیدج بولسأ ثحبلا مدقی قفاوتب ظافتحلاا عم ةتلیخم يف ةنوك يذلا لكشلا ىلع لوصحلا نم ةنكمت ةیلعافت ةقیرطب ى نحنملا طیسلا طاقن عم ىنحنملا میمصتلةعبرلاا ةر . بولسأ ىلع تدمتعا ةروطملا ةیمزراوخلا de Casteljau ينحنم ریوطت يف BEZIER ىلع لاجملا [r, s] ریوطتلل يضایر ساساك . مكحتلا لاجم يف ةیلاع ةنورم ةحرتقملا ةقیرطلا تتبثا لكوأ ضعبریغتب ممصملا ىنحنملاب يف حضوم امك ةرطیسلا طاقن رییغت نود نم وأ يتلا جئاتنلأ

Midcourse Trajectory Shaping for Air and Ballistic Defence Guidance Using Bezier Curves
A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...
متن کامل3D Reconstruction Using Cubic Bezier Spline Curves and Active Contours (Case Study)
Introduction 3D reconstruction of an object from its 2D cross-sections (slices) has many applications in different fields of sciences such as medical physics and biomedical engineering. In order to perform 3D reconstruction, at first, desired boundaries at each slice are detected and then using a correspondence between points of successive slices surface of desired object is reconstructed.

متن کاملPiecewise Bezier Curves Path Planning with Continuous Curvature Constraint for Autonomous Driving
We present two practical path planning algorithms based on Bezier curves for autonomous vehicles operating under waypoints and corridor constraints. Bezier curves have useful properties for the trajectory generation problem. This paper describes how the algorithms apply these properties to generate the reference trajectory for vehicles to satisfy the path constraints. Both algorithms generate t...
متن کاملDegree Reduction of Interval SB Curves
Ball basis was introduced for cubic polynomials by Ball, and was generalized for polynomials of higher degree by Said. An algorithmic approach to degree reduction of interval Said-Ball (SB) curve is presented in this paper. The four fixed Kharitonov's polynomials (four fixed SB curves) associated with the original interval SB curve are obtained. These four fixed SB curves are transformed into f...
