| Or to put it another way: if the smoothmesh drawing code (/airmesh) happened to use triangles instead of quads, would you have kept the old interpolation?
I would have thought about the change a bit longer, but the used interpolation function is still less smooth, less common & very likely slower than the bilinear one. Neither is (/airmesh) default enabled.
Also if I would rewrite Ground.cpp I would just use the bilinear interpolatiom, but I don't rewrite it ;-)
In the case here I didn't bothered with it before either, but now when it was bugged a change was quite obvious.
