使用Python和wxPython的3D/4D图形？

from wx import glcanvas
from OpenGL.GL import *
from OpenGL.GLU import *

class MyCanvas(glcanvas.GLCanvas):

        glClearColor(0, 0, 0, 1)

        glLoadIdentity()
        gluLookAt(0, 0, 5, 0, 0, 0, 0, 1, 0)

        glEnd()

        self.SwapBuffers()

class MyFrame(wx.Frame):

app = wx.App(False)
frame = MyFrame(None, "3D图形")
app.MainLoop()
