[vtkusers] Visualizaing Points with different colors

[Malcolm Drummond]

Hi Asad

You need to add scalar values to your dataset - one for each vertex. Look at Arrays.py in examples/DataManipulation to get started.

  Subject: [vtkusers] Visualizaing Points with different colors


  Hi,
  I would like to visualize a list of points, each with a different
  color. I can visualize them all with the same color, and with 
  the same actor. However, to visualize them in different colors,
  I put each point (vertex) in a different actor. The problem here 
  is that the visualization becomes much slower and a lot of points
  disappear if I zoom out (which doesn't happen when I visualize
  all the points in one actor).

  Is there another easier way to visualize individual points (vertices)
  each with a different color?

  Thanks in advance.

  Asad
