pyqt集成vtk框架

C++环境下，Qt+VTK是一个比较成熟的方案，那python下也可以使用同样的方式也就是PyQt+VTK。

1，VTK安装

pip install vtk

2,Qt安装

3，代码

#!/usr/bin/env python3
 
import sys
import vtkmodules.vtkInteractionStyle
import vtkmodules.vtkRenderingOpenGL2
import vtk
from PyQt5 import QtCore, QtGui, QtWidgets
from vtk.qt.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor
from vtkmodules.vtkFiltersSources import vtkCubeSource
from vtkmodules.vtkRenderingCore import (
    vtkActor,
    vtkPolyDataMapper,
    vtkRenderer
)
class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        QtWidgets.QMainWindow.__init__(self, parent)
        self.frame = QtWidgets.QFrame()
        self.vl = QtWidgets.QVBoxLayout()
        self.vtkWidget = QVTKRenderWindowInteractor(self.frame)
        self.vl.addWidget(self.vtkWidget)
        self.ren = vtkRenderer()
        self.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
        self.iren = self.vtkWidget.GetRenderWindow().GetInteractor()
        # Create source
        source = vtkCubeSource()
        source.SetCenter(0, 0, 0)
        source.SetXLength(1.0)
        source.SetYLength(1.0)
        source.SetZLength(1.0)
        # Create a mapper
        mapper = vtkPolyDataMapper()
        mapper.SetInputConnection(source.GetOutputPort())
        # Create an actor
        actor = vtkActor()
        actor.SetMapper(mapper)
        self.ren.AddActor(actor)
        self.ren.ResetCamera()
        self.frame.setLayout(self.vl)
        self.setCentralWidget(self.frame)
        self.show()
        self.iren.Initialize()

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    sys.exit(app.exec_())
