Cubic Trigonometric Bezier Spiral Curves

摘要

Shape parameters in trigonometric Bezier curves are very useful in providing flexibility to construct the desired curve. It helps users to find the best curve when dealing with designing and modelling tasks. It can simply be used without needing to change control points or using weightage in rational function. A technique for composing five templates of transition curves constructed by cubic trigonometric Bezier spiral is examined and presented.
