[vtkusers] Color Problems

[ivan gm]

Hello vtk users,

I'm representing a bone in 3D generated with the vtkContourFilter. The
following code shows a red bone and a white light illuminating it.My problem
is that I don't know how to configure the actor properties for getting a
grey bone iluminated by a white light.

    vtkContourFilter        *contourFilter = vtkContourFilter::New();
    vtkSmoothPolyDataFilter    *smoothFilter =
vtkSmoothPolyDataFilter::New();
    vtkPolyDataNormals        *polyDataNormals = vtkPolyDataNormals::New();

    contourFilter->SetInput(islandRemoval->GetOutput());
    contourFilter->Update();
    smoothFilter->SetInputConnection(contourFilter->GetOutputPort());
    smoothFilter->SetNumberOfIterations(30);
    smoothFilter->SetRelaxationFactor(1.0);
    smoothFilter->Update();
    polyDataNormals->SetInputConnection(smoothFilter->GetOutputPort());
    polyDataNormals->Update();

    this->BoneMapper->SetInput(this->polyDataNormals->getOutput());
    this->BoneMapper->ImmediateModeRenderingOn();
    this->BoneMapper->Update();
    this->BoneActor->SetMapper(this->BoneMapper);
    this->BoneActor->GetProperty()->SetColor(1.0, 1.0, 1.0);
    this->BoneActor->GetProperty()->SetAmbientColor(1.0, 1.0, 1.0);
    this->BoneActor->GetProperty()->SetSpecularColor(1.0, 1.0, 1.0);
    this->BoneActor->GetProperty()->SetDiffuse(0.0);
    this->BoneActor->GetProperty()->SetSpecular(10.0);
    this->BoneActor->GetProperty()->SetSpecularPower(5);

Can anybody helps me?


Thanks a lot.
