smath

Single-file, header-only linear algebra math library for C++23.

Features

• Generic Vec<N, T> class with useful aliases Vec2/Vec3/Vec4 and friendly accessors (x/y/z/w, r/g/b/a). They support approx-equal and tuple/structured bindings.
• std::format support.
• Compile-time swizzles via swizzle<"...">.
• Generic matrix Mat class with useful aliases Mat2/Mat3/Mat4.
• Quaternion<T> built on Vec4.
• Angle helpers rad/deg/turns respecting a configurable base unit via the macro SMATH_ANGLE_UNIT.
• Optional implicit conversions.
• Packing utilities for normalized RGBA (pack_unorm4x8, unpack_snorm4x8, etc.).
