[Insight-users] Storing non-coordinate information on a mesh

[nadan zhu]

The simplest way is to define your pixel type as
    class PTXPoint
    {
        public:
            typedef itk::RGBPixel<unsigned char> ColorType; //note: the ptx
format uses unsigned chars for color

            ColorType Color;
            double Intensity;
    };

And you instantiate a new meshtraits, like
typedef itk::DefaultStaticMeshTraits<PTXPoint, 3, 3, double, double>
MeshTraits;// since you want the coordinates type is double

then you define your mesh as
typedef itk::Mesh<PTXPoint, 3, MeshTraits>    MeshType;
