Who uses GFM?

Why use GFM

  • GFM primarily provides math primitives that are useful for games like vectors/matrices/quaternions in the gfm:mathpackage.
  • Wrappers are transparent layers that expose the C libraries objects, turn every error code into an D exception and makes it easier to use the library correctly. They do almost nothing and perhaps you don't need them.
  • GFM has low churn and has been maintained since 2012.


You absolutely don't need to use the whole of GFM. Pick just what you need to minimize the amount of dependencies.
