Rendering Text in Metal with Signed-Distance Fields

Warren Moore covers how to use the GPU to add text into a Metal app.

Prior to this post I wasn’t familiar with signed-distance fields, here’s a primer:

“…a precomputed representation of a font atlas that stores the glyph outlines implicitly. Specifically, the texel values of a signed-distance field texture correspond to the distance of the texel to the nearest glyph edge, where texels outside the glyph take on negative values.”

Optimizing System Frameworks for Swift

Matthew Wyskiel on optimizing system frameworks for Swift:

Sounds like a good initiative.

Swift Wrapper for Objective-C JSON Parser

Jameson Quave is the author of LumaJSON:

“An extremely simple and light-weight Swift wrapper for Objective-C JSON parser.”
