Knowledge is not alone, it must be systematic. More my personal summary and related experience can be found in this column: Visual Studio .
For more information about this example, please refer to: 【Visual Studio】Use Visual Studio and Qt to build VTK on Windows .
After completing the example of using Qt to display a small ball, I also tried to download an example from the VTK official website, and then tried to port it to my own Qt project. If you are interested, you can see: [VTK] Official example, ported to my own Qt project, including code .
