pc.calc()

further playcanvas gets a new function pc.calc() which handles assigned arithmetic expressions

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 }
