用python绘制一条直线_python绘制直线的方法

本文实例为大家分享了python绘制直线的具体代码，供大家参考，具体内容如下

#!/usr/bin/env python

import vtk

# 绘制通用方法

def myshow(linepolydata):

# Now we'll look at it.

lineMapper = vtk.vtkPolyDataMapper()

if vtk.VTK_MAJOR_VERSION <= 5:

lineMapper.SetInput(linepolydata)

else:

lineMapper.SetInputData(linepolydata)

lineMapper.SetScalarRange(0, 2)

lineActor = vtk.vtkActor()

lineActor.SetMapper(lineMapper)

# The usual rendering stuff.

camera = vtk.vtkCamera()

camera.SetPosition(1, 1, 1)

camera.SetFocalPoint(0, 0, 0)

renderer = vtk.vtkRenderer()

renWin = vtk.vtkRenderWindow()

renWin.AddRenderer(renderer)

iren = vtk.vtkRenderWindowInteractor()

iren.SetRenderWindow(renWin)

renderer.AddActor(lineActor)

renderer.SetActiveCamera(camera)</
