A while ago i wrote my own vector library with support for arithmetic operator overloading.

But i intensively use playcanvas and didn’t want to mix multiple vector types.

So i have made an adapter combining playcanvas vec2 and vec3 with my Operator class.

I provide a new function on `pc`

object called `calc`

, with that you can make real arithmetic operations.

```
const pos = pc.vec3(5, 6, 7);
const dir = pc.vec3(1, 0, 0);
// pos: { x: 5, y: 6, z: 7 } dir: { x: 1, y: 0, z: 0 }
const offsetA = pc.calc(() => dir * 30 + pos);
// offsetA: { x: 35, y: 6, z: 7 }
```

Here is a small documentation how it can be used.

I hope you enjoy :).
