    No, there is no multiplication.

    Arrays looks like:

    data3D[0, 0, 0] = 0
    data3D[0, 0, 1] = 128
    data3D[0, 0, 2] = 255
    data3D[0, 0, 3] = 255

    data3D[0, 1, 0] = 0
    data3D[0, 1, 1] = 32
    data3D[0, 1, 2] = 64
    data3D[0, 1, 3] = 255
    ...

    and

    data1D[0] = 0
    data1D[1] = 128
    data1D[2] = 255
    data1D[3] = 255
    data1D[4]...

      Fastest byte[,,] to byte[] copy

      Hi,

      I'm doing some video processing and need to copy 3d array of bytes to 1d array of bytes where:

      3d array is [width, height, layers] and
      1d array is [width * height * layers]

      Now i have:
      Code:
      int index = -1;

for (int j = 0; j < h; ++j)
    for (int i = 0; i < w; ++i)
    {
        data1D[++index] = data3D[j, i, 0];
        data1D[++index] = data3D[j,
      ...
