Hi everyone,<br><br>I have a question about vtkCardinalSpline.I want to generate a spline between points selected on the screen.<br><br>Now, how can I know how many points to evaluate the curve on? Basically, say I have 10 points on the screen and I would like the curve to pass through all the 10
points.Normally, I see that the caller divides the area into some arbitrary number of points and calls the Evaluate() method for each of those points.<br><br>However, when I have 10 selected points on the screen, then hwo do I determine how many points I need to evaluate my spline on?? How do the graphics algorithms work. Do they evaluate every position at a specified interval (say
0.25) between the successive points?<br><br>Cheers,<br><br>Anja<br><br>
