Unsolved Qt Quick 2 : Scene Graph Drawing
I have existing C++ application for linux platform which is directly writing on framebuffer fb1 to generate waveform.
Because of framebuffer fb0 and fb1 content overlapping issue we thought to move this application part to another Qt process.
And, I have started with Scene Graph option to go ahead. I know the Geometry and GeometryNode concept but not able to relate with pixel drawing.
Please help me on this as I need to put data as collection of pixel and need to consider CPU usage as well.

I would not use
QProcess(), since it is in C++, using Qt can run on more than one display.
