Hi, great to see you are interested in contributing! Just so you're aware, there's currently some discussion within the team about how we plan on sharing code for the PFD between the A32NX and the A380X since we don't want to have to maintain what is mostly the same codebase in two different places.

As a result, we're not sure if we want to have another instance of largely the same PFD code in the form of the HUD before we've decided on a better structure. I don't want to discourage you from continuing to work on this but wanted to make you aware that you might have to restructure your code if we end up splitting the PFD into reusable components for example.

Unfortunately, I can't say when or even if that's gonna happen, but I want to be fully transparent with you. Other team members are welcome to share their thoughts of course.

It's just a problem that makes me hesitate recently. I notice that there's pillow distortion when MSFS renders the HUD. Not sure about how to correct it. <feDisplacementMap> may help but too tricky.

Try render your test pattern on the default B787 HUD (edit it's panel.cfg), and use the pre-defined HUD camera to view it.
