It’s weird to show console in GUI application for no matter what platform. For the qmake project, the relevant setting is: CONFIG += console CONFIG -= app_bundle We have to remove the console and keep app_bundle for qmake variable CONFIG if we want to hide console when running the program.

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…
The introduction of Just-in-Time (JIT) debugger tool drmingw： https://vroby.ddns.net/Public/sdlBasic/MinGW/doc/drmingw/drmingw.html It’s very easy to install this tool. We can download from the internet and unzip it: It’s necessary to put the directory of the tool bin in the environment variable Path on windows OS. After that, we can run drmingw.exe by Read more…
We have an example which uses cmake to build the qt5 project: use-vtk-in-qt-widget-example But that workflow seems a cheat, I used Qt Creator to create a qmake project and wrote CMakeLists.txt later, regards it as a project file and reopen that project again. I read the introduction of cmake in 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…
SHA is a series of encrypting algorithm which includes sha1, sha256, sha512 and so on. They calculate a checksum based on a file or text string. We can use the result to judge whether two objects are the same. There is a terminal tool called shasum on Unix style operating 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. TCL script: package require vtk vtkConeSource cone vtkPolyDataMapper coneMapper coneMapper SetInputConnection [cone GetOutputPort] vtkActor coneActor coneActor SetMapper coneMapper Read more…
We can use qmake to configure a project for different platforms after reading qt document, Qt 5 > qmake manual > Getting Started. The qmake syntax: macx{ message(“compile for mac os x”) ICON = Images/logo.icns } win32{ message(“compile for windows”) RC_ICONS = Images/logo.ico } Similarly, we can read the target Read more…
