[Solved] Transparent overlay

[Cecile Muller]

First, I love the Gaze Trace overlay, well done 🙂

One thing I’d want to know is how it is able to draw transparent graphics that overlay everything (even the taskbar and fullscreen directx applications) ?

It’s obviously not just a topmost transparent window given it displays even on top of fullscreen DirectX, but I can’t seem to figure out the right Windows APIs to use to make a similar overlay.

Hi @wildpeaks,

Thanks for your interest! Yes, it’s a very cool piece of code for sure 🙂

The program was made in DX11 and C++, but you can get a good idea of the implementation strategy
