我有一个 VTK 卷,我想在 OpenGL 中可视化,如本所示。

如果我理解正确,则会初始化一个 GLUT 窗口,并通过使用 ExternalVTKWidget 完成 OpenGL 中的渲染,但我似乎无法在 Python 中找到它的等价物。有人可以指导/指向正确的方向,或者举一个将 VTK 数据传递到 OpenGL 窗口的示例吗?

这是我目前拥有的代码:

from OpenGL.GL import*
from OpenGL.GLU import*
from OpenGL.GLUT import*
import sys
import math
import vtkmodules.vtkInteractionStyle
import vtkmodules.vtkRenderingOpenGL2
from vtkmodules.vtkCommonColor import vtkNamedColors
from vtkmodules.vtkFiltersSources import vtkConeSource
from vtkmodules.vtkRenderingCore import (
    vtkActor,
    vtkPolyDataMapper,
    vtkRenderWindow,
    vtkRenderer,
    vtkRenderWindowInteractor
)

def plotpoints():
       
    colors = vtkNamedColors()

    cone = vtkConeSource()
    cone.SetHeight(3.0)
    cone.SetRadius(1.0)
    cone.SetResolution(10)
    
    coneMapper = vtkPolyDataMapper()
    coneMapper.SetInputConnection(cone.GetOutputPort())

    coneActor = vtkActor()
    coneActor.SetMapper(coneMapper)
    coneActor.GetProperty().SetColor(colors.GetColor3d('MistyRose'))

    ren1 = vtkExternalOpenGLRenderWindow()
    ren1.AddActor(coneActor)
    ren1.SetBackground(colors.GetColor3d('MidnightBlue'))

    ren1.Render()
    interactor = vtkRenderWindowInteractor()
    interactor.SetRenderWindow(renWin)
    interactor.Start()

def main():
    glutInit(sys.argv)
    glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB)
    glutInitWindowSize(500,500)
    glutInitWindowPosition(50,50)
    glutCreateWindow("Plot Cone")
    glutDisplayFunc(plotpoints)
    glutIdleFunc(plotpoints)
    glutMainLoop()

main()
