ggvec

ggvec is a LuaJIT 2D, 3D, and 4D vector library.

Technical Types

These are the C types used to internally represent the vectors.

Vector type	C type
4D vectors	struct {float x, y, z, w;}
3D vectors	struct {float x, y, z;}
2D vectors	struct {double x, y;}

4D and 3D vectors are only floats so that they can easily fit inside XMM registers. All vectors are 16-byte aligned and all members are packed.
