The article shows how to clip a cone by a plane. The vtkClipPolyData object provides a major algorithm to process the 3D model. Here is python script that describes all details about it. #!/usr/bin/env python import vtk cone = vtk.vtkConeSource() coneMapper = vtk.vtkPolyDataMapper() coneMapper.SetInputConnection( cone.GetOutputPort() ) coneActor = vtk.vtkActor() coneActor.SetMapper( Read more…
The article shows how to use python and Mathematica to do elementary arithmetic with a few examples. The examples come from An Elementary Introduction To The Wolfram Language Calculate 10 to the power 12 python: print( 10**12 ) wolfram: 10^12 => 1000000000000 Compute 2 to the power 2 to the Read more…
The article shows how to use a list in python and Mathematica with a few examples. The examples come from An Elementary Introduction To The Wolfram Language Plot a list that counts up from 1 to 10, then down to 1. wolfram: ListPlot[ Join[ Range[10],Reverse[Range[9] ] ] ] python: import Read more…
The airticle shows how to display list in python and mathematica with a few examples. The examples come from An Elementary Introduction To The Wolfram Language Make a bar chart of { 1, 1, 2, 3, 5 } Python: import matplotlib.pyplot as plt y = (1,1,2,3,5) x = range( len(y)+1 Read more…
This post is similar to 【VTK】A SIMPLE EXAMPLE WRITTEN IN C++ We use python script to do the same thing: create and show a cone in 3D world with the virtualization tool kit. python script: #!/usr/bin/env python import vtk cone = vtk.vtkConeSource() coneMapper = vtk.vtkPolyDataMapper() coneMapper.SetInputConnection( cone.GetOutputPort() ) coneActor = Read more…
