Functions

Const mulV344

  • mulV344(out: Vec | null, m: ReadonlyMat, v: ReadonlyVec): undefined | Vec

  • Multiplies 4x4 matrix m with 3D vector v and assumes initial w=1, i.e. the vector is interpreted as [x,y,z,1]. After transformation applies perspective divide of the resulting XYZ components. Returns undefined if the computed perspective divisor is zero (and would cause NaN results).

    Parameters

    Returns undefined | Vec

Const mulVQ

  • mulVQ(out: null | Vec, q: ArrayLikeIterable<number>, v: ArrayLikeIterable<number>): Vec

  • Multiplies quaternion q with 3D vector v. Returns transformed vector or modifies in-place if out is null or v.

    Parameters

    • out: null | Vec

      -

    • q: ArrayLikeIterable<number>

      -

    • v: ArrayLikeIterable<number>

      -

    Returns Vec
