![]() ![]() Although that makes it very clear to me that no kind of realtime rotation available to NeoGeo would be able to produce results that are as clean as the actual sprite we see above is. ![]() But when you apply the change, final transform looks way, way better, with most of those ruined edges nicely cleaned up. ![]() When you do free transform in Photoshop, the realtime preview of that is a simple matrix transform, which ruins edge lines of the sprite in many places. *edit* Oh wow - Nearest Neighbor does in fact interpolate, I've just witnessed it, it just doesn't interpolate the color, so there's no blurryness added. I don't think it's entirely impossible that the gun tower on that lobster sprite was swaying using some CPU-driven sprite rotation (some Amiga games were able to accomplish that, despite hardware having no support for it - MC68000 had enough grunt to do it), although I think it's unlikely. Rotating it by 1 pixel however introduces some stray pixels around some of the edges - but only very few. Actually, surprisingly enough, that metal slug sprite rotated by 2 degrees in Photoshop using nearest neighbour, looks very respectable. It doesn't interpolate pixels creating blurry looking pixel art. Click to expand.I think that's what nearest neighbour does. ![]()
