This is a utility for generating signed distance fields from vector shapes and font glyphs,

which serve as a texture representation that can be used in real-time graphics to efficiently reproduce said shapes.

Although it can also be used to generate conventional signed distance fields best known from

and pseudo-distance fields, its primary purpose is to generate multi-channel distance fields,

|
using a method I have developed. Unlike monochrome distance fields, they have the ability
|
|
|
to reproduce sharp corners almost perfectly by utilizing all three color channels.
