http://www.gradientspace.com/tutorials/2024/2/20/implicit-surface-modeling The gradient (or derivative) is simply a vector that contains [dU/dX, dU/dY]. For an SDF this should naturally be of unit length and not need to be normalized. Thus, in psuedo code: GetGradient (X,Y) return [GetPartialDerivativeInX (X,Y),GetPartialDerivativeInY (X,Y)] end See more Hopefully after the past 7 posts it’s become clear that a signed distance field gives you the distance to the closest edge from any point.
