[vtkusers] cell color

[John Platt]

Hi Longfei,

 

Did you include #include "vtkCellData.h" in your .cpp file?

 

John.

Hi John:

     thank u for your kindly answer.  I use below to set the cell scalar
and get some problem.

 surf->GetCellData()->SetScalars(surscalar);

 

//###############


D:\cong\normalperson\tensorvisual.cpp(4739) : error C2027: use of
undefined type 'vtkCellData'
        D:\dvtk\Common\vtkDataSet.h(46) : see declaration of
'vtkCellData'
D:\cong\normalperson\tensorvisual.cpp(4739) : error C2227: left of
'->SetScalars' must point to class/struct/union
Error executing cl.exe.

Hi Longfei,

 

Have you tried adding cell scalars and changing the mapper colour mode
if the default behaviour is not applicable. If you create the scalars as
unsigned chars with 3 components, for example, these will be mapped
directly as RGB and not through the lookup table. Have a look at
vtkMapper::SetColorMode().

 

John.

Dear Vtkusers:

  I use the vtkPolyData to show a surface and  want to set diefferent
cells with different color. Wish someone can help me!!
