Advice please on application design



  • I'm still climbing the OpenGL-Qt learning curve, finding the vast amount of documentation a bit overwhelming, and would appreciate some specific advice on application design and specific Qt classes to use. I'd like to write an application that displays a topographic map in a perspective view in a main window. That main window will also include menus and buttons to control the map display - view/light-source geometry, color map, etc. I want the app to be portable to both desktop or mobile, so will develop the GUI using QML. The datasets are very large (> 1GB) so speed is of the essence; I'll develop the "business logic" with C++. I want to use OpenGL with modern programmable pipeline, not the deprecated immediate mode. How best to represent the main window and the map display? Can someone refer me to an example that implements something close to my application? Any advice is much appreciated!

    Thanks
    Tom

    Have a look at these examples: https://doc.qt.io/qt-5/datavisualization-examples.html There's a mix of Widgets and Qt Quick (QML) examples there.



  • @JKSH - very useful, thanks!
