파이썬에서 튜플을 사용하여리스트에서 vtkPolyData 객체를 생성하십시오.

Question

저는 파이썬에 대해 처음 접했고 (x, y, z 좌표로) 튜플 목록을 가지고 있습니다. 이들로부터 vtkPolyData-object를 만들고 싶습니다. 어떻게해야합니까?

이 시도 :

#!/usr/bin/env python 

import vtk 

# Create the geometry of a point (the coordinate) 
points = vtk.vtkPoints() 
p = [1.0, 2.0, 3.0] 

# Create the topology of the point (a vertex) 
vertices = vtk.vtkCellArray() 

id = points.InsertNextPoint(p) 
vertices.InsertNextCell(1) 
vertices.InsertCellPoint(id) 

# Create a polydata object 
point = vtk.vtkPolyData() 

# Set the points and vertices we created as the geometry and topology of the polydata 
point.SetPoints(points) 
point.SetVerts(vertices) 

# Visualize 
mapper = vtk.vtkPolyDataMapper() 
if vtk.VTK_MAJOR_VERSION <= 5: 
    mapper.SetInput(point) 
else: 
    mapper.SetInputData(point) 

actor = vtk.vtkActor() 
actor.SetMapper(mapper) 
actor.GetProperty().SetPointSize(20) 

renderer = vtk.vtkRenderer() 
renderWindow = vtk.vtkRenderWindow() 
renderWindow.AddRenderer(renderer) 
renderWindowInteractor = vtk.vtkRenderWindowInteractor() 
renderWindowInteractor.SetRenderWindow(renderWindow) 

renderer.AddActor(actor) 

renderWindow.Render() 
renderWindowInteractor.Start()
