[vtkusers] Create PolyData in vtk.js

[Sebastien Jourdain]

I was starting to answer your previous email but I'm glad you figure it out.

But I'm not sure what it your new question.
1) How to add data to the polydata?
2) How to render an array from a polydata for both points and cells?

Seb

PS: You could create an issue for that topic on vtk.js is you want too.
