I'm working on a new (C++) navigation display instrument, which I hope to add a proper EGPWS terrain display layer too - replacing Skyop's Nasal version, with his full and happy consent :) I already reviewed the ground cache code, but I wan't sure how performant it would be, to scan the ND range (eg, 80, 160 or 320nm) at, say, 10 or 50m intervals. The problem is the EGPWS needs relative altitude to the aircraft, but in real-life the update isn't instantaneous, especially at longer ranges, so I expect to perform the scan incrementally over a few seconds.
