[vtkusers] Help with visualisation of pressure sketches

[Sylvain Jaume]

Hi Monica,

Would a vtkGlyph2D and vtkPolyDataMapper be a solution for you?
Use vtkGlyph2D::ScalingOn()
and vtkGlyph2D::SetScaleModeToScaleByScalar()

HTH,

Hello,
on a 2D image I must visualise pressure sensitive marks
like the ones that you can make with gimp brushing.
The input data  (scalar values for the pressure
and the point coordinates) will be stored into a vtkPolyData.

Can anybody suggest me which are the best mapper
or filter that I can use with the vtkAct2D to get the brush-like effect
with thickness varying according to the pressure input?

Any reference example?

Thanks a lot,

Monica
