[vtkusers] Embed VTK in a GUI

[Andras Lasso]

If you need a full-featured application then you may also consider customizing/extending existing VTK-based open-source applications that embed Python. Using Python scripting, you can build up your application GUI from plain low-level Qt widgets and bring in any additional application-specific widgets as needed; and access to all the features that these application provide. You can build on Paraview for general technical visualization, 3D Slicer for medical image computing, etc.

My recommendation is to use PySide (https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.qt.io%2FQt_for_Python&data=02%7C01%7Classo%40queensu.ca%7C9040f7185e0842ecf59808d6069a0205%7Cd61ecb3b38b142d582c4efb2838b925c%7C1%7C0%7C636703655886230803&sdata=iIVPxJtVxy985WoXTk%2BRWVNghkfXufiuVuUcVjIL1Ic%3D&reserved=0), the official Python bindings for Qt. I have used Python and PySide (the old one), PyQt4, and PyQt5 to maintain a VTK based GUI for many years, they work well together. Good luck.

Subject: [vtkusers] Embed VTK in a GUI

Hi everyone,

I have a computational modeling program that has been written in Matlab. I developed a GUI in Matlab and used VTK to visualize and interact (transform, cut, deform, etc.,) CAD models. However, Matlab GUI does not support embedding VTK, resulting in a separate Matlab GUI and a VTK rendering window. I have looked for options to embed VTK in a GUI that works similar to 3D Slicer. I know that I can do it in Qt, Python and PyQt, Python and Tk, Jave, and C#.

The problem is my program consists of many matrix-based calculations that may take a great deal of effort if I develop the program in Qt and C#.
Python is quite close to Matlab that I think I can develop the program in a short period and save time.

For those who have experience in developing an app using VTK and PyQt, please let me know I should use VTK and PyQt4 or PyQt5 and why?

Also, if you think Qt or C# can work more efficiently than Python (I don't have much experience in Qt), please let me know your thoughts and share with me how I can work efficiently with matrices in Qt and C#.

Thanks in advance. I do appreciate any input.

Regards,
Manh
