C++ (Cpp) DeviceArray2D Examples

Example #1

bool

{
    int volume_size = device_volume_.rows() * device_volume_.cols();

        return false;
    }

    vector<VoxelT>&  volume_vec  = volume->volumeWriteable();
    vector<WeightT>& weights_vec = volume->weightsWriteable();

    device_volume_.download (&volume_vec[0], device_volume_.cols() * sizeof(int));
