I am creating a mapper (tileMapper) to render a polygon, using the same code as in the Wiki example polygon.cxx. I expect to be able to set the color when I create an actor:<br>
<br>
double tileColor[] = {0.5, 0.5, 0.0};<br>
actor = vtkActor::New();<br>
actor->SetMapper(tileMapper);<br>
actor->GetProperty()->SetColor(tileColor);<br>
<br>
but it doesn't work. The tile always displays with the color that was set when the PolyData used by tileMapper was created:<br>
<br>
polygonPolyData->GetCellData()->SetScalars(colors);<br>
<br>
The method I'm using (unsuccessfully) to set the color is the same I use with other mappers, created using vtkSphereSource, for example.<br>
<br>
How should I be doing it?<br>
