Some hotkeys of RenderWindowIterator are useful for developers to debug. The content comes from VTKUsersGuide.pdf Keypress j / Keypress t — Toggle between joystick (position sensitive) and trackball (motion sensitive) styles. In joystick style, motion occurs continuously as long as a mouse button is pressed. In trackball style, motion occurs Read more…
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…
vtkRandomGraphSource can be used to create a random graph which includes points and edges. vtkGraphLayoutView is a vtkRenderView which has its own renderer and iterator, we can use it to display graph view. from vtk import * # create a random graph source = vtkRandomGraphSource() source.SetNumberOfVertices(100) source.SetNumberOfEdges(110) source.StartWithTreeOn() #create a Read more…
I often use the function AddInputData or AddInputConnection of vtkAppendPolydata that inherits vtkDataObjectAlgorithm to add multiple polydatas form a big one. That’s a very easy way to combine a few of different polydatas to only one. But I found that it can give me a strange result if I use Read more…
Environment: macOS Mojave 10.14 Qt Creator 4.41 Qt 5.9.2 Clang 7.0 apple, 64 bits VTK 8.1.1 Our project shows: Add 3D model in VTK widget means we need to intergrate VTK and Qt development environment. Here are a few notes about it. I put a cone in QVTKOpenGLWidget, and there 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…
This post is similar to 【VTK】A SIMPLE EXAMPLE WRITTEN IN C++. We use TCL script to do the same thing: create and show cone in 3D world with the virtualization tool kit.
