[vtkusers] Data Color

[Sylvain Jaume]

Hi Tarak,

You could create an array of unsigned char values (modulo 256) and set 
it to your polydata cell data.

int numCells = polyData->GetNumberOfCells();
vtkUnsignedCharArray *ucharArray = vtkUnsignedCharArray::New();

for (int i=0;i<numCells;i++)
{
ucharArray->InsertNextValue(i%256);
}

polyData->GetCellData()->SetScalars(ucharArray);
ucharArray->Delete();

Cheers,
Sylvain
