C++ (Cpp) update_fourth_quadrant Examples

Example #1

void OutCoreInterp::updateInterpArray(int fileNum, double data_x, double data_y, double data_z)
{
    double x;
    double y;

    int lower_grid_x;
    int lower_grid_y;

    lower_grid_x = (int)floor((double)data_x/GRID_DIST_X); // global/local coordinate
    lower_grid_y = (int)floor((double)data_y/GRID_DIST_Y); // global coordinate

    x = data_x - lower_grid_x * GRID_DIST_X;
    y = data_y - lower_grid_y * GRID_DIST_Y;


    //if(lower_grid_y == 30 && data_y > GRID_DIST_Y * lower_grid_y)
    //printf("(%f %f) = (%d, %d)\n", data_x, data_y, lower_grid_x, lower_grid_y);

    // if the opened file is not the 0th file, then you have to consider the offset of the grid of the file!!!
    lower_grid_y -= gridMap[fileNum]->getOverlapLowerBound(); // local coordinate

    //cout << fileNum << ":(" << lower_grid_x << "," << lower_grid_y << ")" << endl;

    update_first_quadrant(fileNum, data_z, lower_grid_x + 1, lower_grid_y + 1, GRID_DIST_X -x, GRID_DIST_Y - y);
    update_second_quadrant(fileNum, data_z, lower_grid_x, lower_grid_y + 1, x, GRID_DIST_Y - y);
    update_third_quadrant(fileNum, data_z, lower_grid_x, lower_grid_y, x, y);
    update_fourth_quadrant(fileNum, data_z, lower_grid_x + 1, lower_grid_y, GRID_DIST_X - x, y);
