Function setTrsl

  • Sets the elements of the 3x3 matrix m so it becomes a 2D translation matrix.

    Multiplying the resulting matrix by a column vector will translate the given vector by [ tx ty ] (see mulV)

    Parameters

    • m: Mat3

      a 3x3 matrix object

    • tx: number

      the amount of translation along the x-axis

    • ty: number

      the amount of translation along the y-axis

    Returns Mat3

    m set to be a 2D translation matrix
