I have a vectorimageSlices and a 3D :

cv::Mat RTstruct3D(3,DImensions3D, CV_8U, Scalar(0))

I want to put my vector into the specific index of 3D cv::Mat.

        //Make a 3D Organ
        int programCounter = 0;
        vector<Mat>imageSlices;
        for (size_t k = 0; k < Npoint_Z.size(); k  )
        {
            Mat finalSliceImage = Mat :: zeros(DImensions3D[0], DImensions3D[1],CV_8U);
            vector<vector<int>> polies;
            for (size_t h = 0; h < Npoint_Z[k][0]; h  )
            {
                vector<int>x_y;
                x_y.push_back(ContourData[programCounter][0]); //x
                x_y.push_back(ContourData[programCounter][1]); //y
                polies.push_back(x_y);
                programCounter  ;
            }
            fillPoly(finalSliceImage, polies, Scalar(0, 255, 0));
            imageSlices.push_back(finalSliceImage);
        }
        //Add Organ to RTSTRUCT 3D
        Mat RTstruct3D(3,DImensions3D, CV_8U, Scalar(0));

Something like this image:

Please help me! Thanks.

You can try to use Mat cv::Mat::operator() ( const std::vector< Range > & ranges ) const to access the submatrix and then use Mat& cv::Mat::operator= ( const Mat & m )

Example:

int main() {
    cv::Mat m1(10, 10, CV_8U, cv::Scalar(1));
    vector<cv::Mat> v = {m1, m1, m1};
    std::array<int, 3> dims = {10, 10, 10};
    cv::Mat m2(3, dims.data(), CV_8U);
    vector<cv::Range> rV = {cv::Range(0, 1), cv::Range(0, 10), cv::Range(0, 10)};
    m2(rV.data()) = v[0];
    return 0;
}

vector<Mat> RTstruct3D(DImensions3D[0]);
for (size_t f = 0; f < Npoint_Z.size(); f  )
{
    RTstruct3D[Npoint_Z[f][1]] = imageSlices[f];
}
