## Quick Start
Create `main.cpp`:
```cpp
#include
#include
int main() {
using namespace smath;
Vec3 a{1.0f, 2.0f, 3.0f};
Vec3 b{3.0f, 2.0f, 1.0f};
std::println("a + b = {}", a + b);
std::println("dot(a, b) = {}", a.dot(b));
std::println("normalized(a) = {}", a.normalized());
}
```
Build and run:
```bash
g++ -std=c++23 -Iinclude main.cpp -o quickstart
./quickstart
```
## Features
- Generic `Vec` 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` 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.).
- C++20 modules support.
