I’m glad to share with you my current progress. As you can see, I’ve loaded landscape (with hacks that I’ll fix later), loaded animations and added basic post-processing – color correction and FXAA. I also wrote linear approximation to AH’s flight model, it works pretty well, but another approach is required to get exact formulas. What’s next? Clouds, perhaps.
Graphics isn’t so close to original, because there are lots of things to do. I’ve only written simple shaders so as not to make one’s eyes bleed.
