Hi all,<br><br>I would like to be able to "build" an odd-shaped, convex, cylinder. I imagine that I would first use a series of mouse clicks to define the perimeter (much like vtkContourWidget, except with straight lines joining the points), and then be able to change the length of the cylinder.<br>
<br>I'd like to be able to move and change the cylinder's points (again like the vtkContourWidget).<br><br>I'm not really sure how I can do this in the VTK way.<br><br>Can someone *please* give me some pointers? Some sort of starting point would be great.<br>
<br><br>The end goal is to allow the user to define one, two, or more "cylinders" in 3d space, and the intersection of the cylinders (via vtkHull, perhaps) would be a 3d convex polygon that can be captured and used for selecting a 3d volume/space.<br>
<br><br>thanks,<br>Paul<br><br><br>
