<br>
I want to generate a curved line by VTK. Now I have the coordinates(xyz) of<br>
two points. One is the start point and the other one is the end point. The<br>
tangent vectors on two points are also known. <br>
<br>
Firstly, I use the vtkArcSource to generate the arc line. But sometimes the<br>
four elements can not just right define a circle.<br>
<br>
Now, I have no idea about this question. I am looking for your help.<br>
<br>
Best regards,<br>
Frank<br>
