<P>I am using a point set to represent the branches of a 3 dimentional object like a tree. I connect the points with lines to show the branches. Then I use the radius information and the vtkTubeFilter to create the cylindrical branch sturcture that varies by radius at each point.</P>
<P>I have two problems with this:</P>
<P>1) The first is the tubes are discontinuous at each point making it look like cylinders backed up to each other rather than a smooth branch.</P>
<P>2) The second problem is I would like to (probe?) the data from a volume and color the branch structure with these values.</P>
<P>I am not sure how to accomplish this because I am not aware of everything vtk can do. I think I need to do some sort of transformation after the tube filter is applied. Like a surface reconstruction of some kind.<BR><BR>Any help is appreciated. Thanks!</P>
