[vtkusers] Fwd: webgl output of VTKPolyData.py

[Sebastien Jourdain]

Hi Jian,

the reason here is that the data you try to look at is not a scalar field
but a RGBA type of information.
The WebGL exported is looking for a field (I think) and get confused.

You may need to generate a field here and use a lookup table with it. You
can also try to use ParaView to load and export the data in WebGL.
