Function: dotVec()

dotVec(a, b): number

Defined in: utils/vectors.ts:78

3D dot product (a · b). Accepts plain number arrays so callers that use number[] (e.g. internal helpers in math.ts) can share the same impl.

Missing components default to 0 so 2D points ([x, y]) are handled.

Parameters

a

ArrayLike<number>

b

ArrayLike<number>

Returns

number
