I have a height map(with NAN value) and a 2d image.
Part of my code:
vtkSmartPointer imageImport = vtkSmartPointer::New();
imageImport->SetDataSpacing(1, 1, 1);
imageImport->SetDataOrigin(0, 0, 0);
imageImport->SetWholeExtent(0, cols - 1, 0, rows - 1, 0, 0);
imageImport->SetDataExtentToWholeExtent();
imageImport->SetDataScalarTypeToUnsignedChar();
imageImport->SetNumberOfScalarComponents(3);
imageImport->SetImportVoidPointer((void*)imgPtr);
imageImport->Update();
vtkSmartPointer<vtkDelaunay2D> delaunay = vtkSmartPointer<vtkDelaunay2D>::New();
delaunay->SetInputData(polydata);
delaunay->Update();
vtkSmartPointer<vtkSmoothPolyDataFilter> smoothFilter = vtkSmartPointer<vtkSmoothPolyDataFilter>::New();
smoothFilter->SetInputConnection(delaunay->GetOutputPort());
smoothFilter->SetNumberOfIterations(30);
smoothFilter->SetRelaxationFactor(0.05);
smoothFilter->FeatureEdgeSmoothingOff();
smoothFilter->BoundarySmoothingOn();
smoothFilter->Update();
// Update normals on newly smoothed polydata
vtkSmartPointer<vtkPolyDataNormals> normalGenerator = vtkSmartPointer<vtkPolyDataNormals>::New();
normalGenerator->SetInputConnection(smoothFilter->GetOutputPort());
normalGenerator->ComputePointNormalsOn();
normalGenerator->ComputeCellNormalsOn();
normalGenerator->Update();
vtkSmartPointer<vtkPolyDataMapper> smoothedMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
smoothedMapper->SetInputConnection(normalGenerator->GetOutputPort());
vtkSmartPointer<vtkActor> smoothedActor = vtkSmartPointer<vtkActor>::New();
vtkSmartPointer<vtkTexture> texture = vtkSmartPointer<vtkTexture>::New();
texture->SetInputConnection(imageImport->GetOutputPort());
double bounds[6];
smoothFilter->GetOutput()->GetBounds(bounds);
smoothFilter->SetEdgeAngle(60.0);
smoothFilter->SetFeatureAngle(60);
vtkSmartPointer<vtkTextureMapToPlane> texturemap = vtkSmartPointer<vtkTextureMapToPlane>::New();
texturemap->SetInputData(smoothFilter->GetOutput());
texturemap->SetOrigin(bounds[0], bounds[2], bounds[4]);
texturemap->SetPoint1(bounds[1], bounds[2], bounds[4]);
texturemap->SetPoint2(bounds[0], bounds[3], bounds[4]);
smoothedMapper->SetInputConnection(texturemap->GetOutputPort());
smoothedActor->SetMapper(smoothedMapper);
smoothedActor->SetTexture(texture);
but the effect is just so so !
Now I do not know how to process can get the effect picture is as below:
