Math Structs (FFI)

Module defined in lua/common/cdefMath.lua. Defines FFI C structs for vec3 and quat types used by the math library.

---

Exports

No Lua exports. Registers FFI C struct definitions when ffi is available.

FFI Types

__luaVec3_t

• Type: FFI struct {double x, y, z}
• Description: 3D vector with double precision. Used as the backing type for vec3().

__luaQuat_t

• Type: FFI struct {double x, y, z, w}
• Description: Quaternion with double precision. Used as the backing type for quat().

Internal Notes

• These structs are metatyped in mathlib.lua to provide operator overloading and methods
• Uses double precision (not float) for accuracy in physics calculations
