Obviously making a smooth curve for us humans is easier with splines, but when an airport has a visually adequate curve made by the AI, is there any advantage to redoing that using splines?
So far, I’ve only used splines where I felt I needed to alter or add a curved apron.
I don’t have a good answer for this, but I’m answering it in the hopes that it will spark other conversation. My thought is that if it ain’t broke, don’t fix it. I would assume/hope that the AI system would find an optimal balance for FPS, and if it looks good already, there isn’t much of a need to change it. But I definitely welcome other opinions on this matter.
