Question slightly related to this topic: how do native (e.g. Qt, GTK, etc.) desktop applications usually embed 3D views? Say for example, a desktop application for visualizing .obj files. Or something like AutoCAD, maybe (though I’m not sure which UI framework it uses).

Not sure if this is what you're asking :) but the UI framework will somehow provide access to the OS-level surface object, so that the GPU API can render directly to the screen.

Makes sense!
