SDFs in 2D A signed distance function in 2D is more straightforward to reason about so we’ll cover it first. Additionally, it is helpful for font rendering in specific scenarios.

It is proved here that this restricted mean value property implies h is harmonic under certain conditions. This monthly journal, published since 1900, is devoted entirely to research in pure and ...
