[vtkusers] plane blending problem!!

[jose manjon]

Hi there,

I am using a plane for representing cutting plane on a volume rendering program.

I have a problem . I want to blend the plane anmd for this I use SetOpacity(0.5).

but no way the code is this:

pmaxz=vtkPlaneSource::New();
pmaxz->SetNormal(-1,0,0);
pmaxz->SetOrigin(-ancho/2,-alto/2,fuentes/2);
pmaxz->SetPoint1(-ancho/2,alto/2,fuentes/2);
pmaxz->SetPoint2(ancho/2,-alto/2,fuentes/2);

pmaxzMapper=vtkPolyDataMapper::New();
pmaxzMapper->SetInput(pmaxz->GetOutput());

pmaxzActor=vtkActor::New();
pmaxzActor->SetMapper(pmaxzMapper);
pmaxzActor->GetProperty()->SetOpacity(0.5f);
pmaxzActor->GetProperty()->SetColor(0,0,1);

this->Renderer->AddActor(pmaxzActor);


any idea???

thanks in advance,

jose
