[vtkusers] Color Mapping using scalar cell attribute data

[John Platt]

Hi vtkUsers,

 

I am trying to color map using different components of scalar cell
attribute data. I cannot find a way of changing 'ArrayComponent' in
vtkMapper.cxx to another value other than zero (except in the
debugger!).

 

I have tried vtkMapper->ColorByArrayComponent( "Element Attribs", 1 )
but by the time vtkMapper->MapScalars() is called, the component has
been reset to 0 again.

 

Any suggestions?
