Pyvista reads VTK files to render 3D cloud images and slice and crop them (1)
Pyvista official documentation: https://qtdocs.pyvista.org/index.html The following code was written by me after checking the official documentation API, and it contains the translation of the official API. The notes are very detailed, so the author won’t go into details. Three-dimensional cloud drawing effect: Surface: Surface + Mesh: Gridlines: Surface Points + Right-click to select Show Data: […]
VTK+QT implementation, displaying three two-dimensional three-dimensional views of the three-dimensional model
The renderings are as follows: This code uses QT and VTK libraries to display three three-dimensional views of the three-dimensional model on the interface. First, read the NIFTI image data through vtkNIFTIImageReader, and then create three rendering windows (coronal, sagittal, and axial views) to display images of the coronal, sagittal, and axial views respectively. Next, […]

vtk implements two methods of segmenting images and overlaying display of original images
1. Implemented with vtkImageBlend vtkLookupTable implements the mapping of grayscale images to color images, and vtkImageBlend overlays grayscale images and color images. The specific code is as follows: //Segmented image vtkSmartPointer<vtkLookupTable> pColorTable = vtkSmartPointer<vtkLookupTable>::New(); pColorTable->SetNumberOfColors(2); pColorTable->SetTableRange(0, 255); pColorTable->SetTableValue(0, 0.0, 0.0, 0.0, 0.0); pColorTable->SetTableValue(1, 0, 1, 0, 1.0); pColorTable->Build(); vtkSmartPointer<vtkImageMapToColors> colorMap = vtkSmartPointer<vtkImageMapToColors>::New(); colorMap->SetInputData(outImage); colorMap->SetLookupTable(pColorTable); colorMap->Update(); […]
