PyQt5 -VTK 開發

查了一堆的文章，都沒有找到pyside2支援vtk的QVTKRenderWindowInteractor的方法，隻好回到PyQt5的狀态。

同樣，python37的版本。

我們希望通過一系列的案例來講解VTK的使用。

首先是一個簡單的案例

import sys
from PyQt5 import (QtWidgets, QtCore)
from PyQt5.QtWidgets import QHBoxLayout
import vtk
from vtk.qt.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(603, 553)

        self.centralWidget = QtWidgets.QWidget(MainWindow)
        self.gridlayout = QtWidgets.QHBoxLayout(self.centralWidget)
        self.vtkWidget = QVTKRenderWindowInteractor(self.centralWidget)
        self.gridlayout.addWidget(self.vtkWidget)
        MainWindow.setCentralWidget(self.centralWidget)


class SimpleView(QtWidgets.QMainWindow):

    def __init__(self, parent=None):
        QtWidgets.QMainWindow.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ren = vtk.vtkRenderer()
        self.ui.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
        self.iren = self.ui.vtkWidget.GetRenderWindow().GetInteractor()

        # Create source
        source = vtk.vtkSphereSource()
        source.SetCenter(0, 0, 0)
        source.SetRadius(5.0)

        # Create a mapper
        mapper = vtk.vtkPolyDataMapper()
        mapper.SetInputConnection(source.GetOutputPort())

        # Create an actor
        actor = vtk.vtkActor()
        actor.SetMapper(mapper)

        self.ren.AddActor(actor)


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = SimpleView()
    window.show()
    window.iren.Initialize()  # Need this line to actually show the render inside Qt
    sys.exit(app.exec_())
           

運作結果如圖
