在PySide中嵌入VTK

在用C++时，作为官方搭配，Qt和VTK是一对好基友，本文试试python下这对基友是否暧昧依旧？ 这里用的是Qt的python版本：PySide，下载官方编译好的python支持包：vtkpython-6.3.0-Windows-64bit.exe。

0.环境变量：

Path : D:\Program Files\VTK 6.3.0\bin;

PYTHONPATH : D:\Program Files\VTK 6.3.0\bin\Lib\site-packages;

1. 导入vtk包：

import vtk

from vtk import *

测试VTK是否可用：

print vtk.vtkVersion.GetVTKSourceVersion()

2. 测试代码：

import vtk    

cone_a=vtk.vtkConeSource()    

coneMapper = vtk.vtkPolyDataMapper()  
coneMapper.SetInputConnection(cone_a.GetOutputPort())  
  
coneActor = vtk.vtkActor()  
coneActor.SetMapper(coneMapper)    
  
ren1= vtk.vtkRenderer()  
ren1.AddActor( coneActor )  
ren1.SetBackground( 0.1, 0.2, 0.4 )  
  
renWin = vtk.vtkRenderWindow()  
renWin.AddRenderer( ren1 )  
renWin.SetSize( 300, 300 )  
renWin.Render()  
  
iren=vtk.vtkRenderWindowInteractor()  
iren.SetRenderWindow(renWin)  
  
iren.Initialize()  
iren.Start()

3. GUI，只贴出main.py，自动生成的ui.py就不贴了。这样写挺烦，不过之后应该能封装。嗯，先这样，一步一步来。

from PySide import QtCore, QtGui
from PySide.QtGui import QApplication

import vtk
from vtk.qt4.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor
import sys

class MWindow(QMainWindow,Ui_MainWindow):
    def __init__(self, parent=None):
        super(MWindow,self).__init__(parent)
        self.ui = Ui_MainWindow()
        self.setupUi(self)

        self.ui.gridlayout = QtGui.QGridLayout(self.widget)
        self.ui.vtkWidget = QVTKRenderWindowInteractor(self.widget)
        self.ui.gridlayout.addWidget(self.ui.vtkWidget, 0, 0, 1, 1)

        self.ren = vtk.vtkRenderer()
        self.ui.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
        self.iren = self.ui.vtkWidget.GetRenderWindow().GetInteractor()

......
# Create source
source = vtk.vtkConeSource()

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

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

self.ren.AddActor(actor)
self.ren.SetBackground( 0.1, 0.2, 0.4 )
......

# Main Function
if __name__=='__main__':
    app = QApplication(sys.argv)
    Window = MWindow()
    Window.show()
    Window.iren.Initialize()
......
    sys.exit(app.exec_())
    #Program.exec_()

总是想做的太多，能做的太少，时间和精力只有那么多，所以整个故事的结果就又交给了选择，哎~~！
