[vtkusers] Drawing vtkTree

[Eric E. Monson]

Hello Juan Carlos,

You can show your tree with a vtkGraphLayoutView, but use SetLayoutStrategyToPassThrough() so it won't try to do any layout on the graph. With that layout strategy it will just use the coordinates that are already stored in the tree/graph.

Good luck,
-Eric

I have an algorithm that collects a number of points from an image and it stores them in the vtkTree, I'm using a MutableDirectedGraph and a vtkDoubleArray to store the coordinates of each point, then assigning the Array to the Graph and finally converting them to a vtkTree.
