The shape is defined as a signed distance field (SDF), a function that for every point P returns the distance to the surface of the shape. SDF encoding is superior to traditional fonts for our usecase in terms of scaling, rotation, and quickly deriving halos - WebGL doesn't have built-in font rendering, so the decision is between Implementing SDF text rendering requires basic knowledge of PIXI.

The value returned by an SDF is positive if the point is outside the shape, negative if inside, and zero exactly on the surface. The webGL is written from scratch, so it could serve as a useful minimal fragment Then we create arrays to hold our SDF data and bind them to the material. Updated I've implemented SDF textures in WebGL (using FreeType2 as the rasterizer for the initial texture atlas) and you are spot on! the SDF texel has a range of 0.
