v(x: number, y: number, z: number) → vector

vec(p: any) → vector

Accept a vector, {x,y,z}, {x=,y=,z=} or an entity transform value.

arr(v: vector) → void

len(v: vector) → number

norm(v: vector) → vector

dot(a: vector, b: vector) → number

rotate(q: any, v: vector) → vector

Rotate v by quaternion q = {x,y,z,w}.

lookQuat(dir: vector) → void

Quaternion {x,y,z,w} that turns -Z to face `dir` with +Y kept up.

qmul(a: { number }, b: { number }) → void

euler(pitch: number, yaw: number, roll: number) → void

Quaternion from Euler degrees (pitch about X, yaw about Y, roll about Z), applied yaw * pitch * roll.

axis(x: number, y: number, z: number, deg: number) → void

rng(seed: number) → void

Deterministic random stream (same seed → same numbers on every peer).
