<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I'm drawing a circle wherever the user clicks on my image. </DIV>
<DIV> </DIV>
<DIV>Now, I would like an interpolation line to be drawn between each point of my glyph. I take a look on that and see that I can use <STRONG>vtkCardinalSpline</STRONG>. </DIV>
<DIV> </DIV>
<DIV>- What I don't know to do is to <STRONG>interpolate my points in the mean time that the users clicks:</STRONG> my spline has to length itself and to be reevaluated after each click.</DIV>
<DIV> </DIV>
<DIV><STRONG>- vtkSplineFilter</STRONG> is also mentioned and maybe this could help me. However, I didn't find any example of this filter, except test file. Has anyone already used this filter?</DIV>
<DIV> </DIV>
<DIV>- Does someone know how I could handle all of this, while being interactive with the user. </DIV>
<DIV>All examples that I read so far deal with vtkPolyData set once and not increasing with user clicks.</DIV>
<DIV> </DIV>
<DIV>Please give me any idea.</DIV>
<DIV> </DIV>
<DIV>Isabelle </DIV><p>
