    // point.

    // "u", "v" - row and column (respectively) in the left stereo image.
    // This is opposite to usual conventions but remains for
    // historical reasons. The newer PointCloud2 message has no
    // such problem.
    // "rgb" - For point clouds produced by color stereo cameras. uint8
    // (R,G,B) values packed into the least significant 24 bits,
    // in order.
    // "intensity" - laser or pixel intensity.
    // "distance"

    // "intensity" instead of "value").
