A NEW PLANAR BEZIER-LIKE SPIRAL DEFINED BY EXPONENTIAL FUNCTIONS AND TRANSITION CURVES

In this paper, we first obtain a new spiral curve by using the curve introduced by Zhu-Han [14] under certain restrictions. Then by using this spiral curve, we construct five transition curves which are from a circle to a line, from a circle to a circle with the C-shaped curves, from a circle to a circle with the S-shaped curves, from a line to a line and from a circle to a circle, one circle inside the other.
