[opengl]obj loader

Hi, Firstly i want to apologize about my language.

Ok, then i have some problems with every obj loaders, if it's main or i download from internet i couldn't play it. This is the result of all of obj loader with opengl and (winapi or SDL) it's look: http://img151.images.../2458/asd2u.jpg

struct xyz{
    float x;
    float y;
    float z;
};
struct abcd{
    int a;
    int b;
    int c;
    int d;
};
std::vector < xyz > wieszcholki;
std::vector < xyz > wieszcholki_normalne; //ma zawierać paramerty wieszchołka
std::vector < abcd > sciana ;  //ma zawierac kolejnosc wysowaniania
void rys(void){
    std::ifstream in( "diamond.obj" );
    std::string buffer;
    std::string tmp;
    xyz v , vn;
    abcd f;
    std::string tbl[4];
    while( !in.eof() )
    {
        std::getline( in, buffer );
        std::istringstream line( buffer );
        std::string ch = buffer.substr( 0, 2 );
        if( ch == "v " ) // wczytanie parametrów wieszchołka
        {
            line >> tmp >> tbl[0] >> tbl[1] >> tbl[2];
            v.x = atof( tbl[0].c_str() );
            v.y = atof( tbl[1].c_str() );
            v.z = atof( tbl[2].c_str() );
            wieszcholki.push_back(v);
            std::cout << "wierzcholki v1: " << v.x << " v2: " << v.y << " v3: " << v.z << std::endl;
        }
        
        else if( ch == "f " ) // wczytanie kolejnosci
        {
             char sc[128];
             strncpy(sc, buffer.c_str(), 128);
            line >> tmp >> tbl[0] >> tbl[1] >> tbl[2] >> tbl[3];
            f.a = (int)atof( tbl[0].c_str() )-1;
            f.b = (int)atof( tbl[1].c_str() )-1;
            f.c = (int)atof( tbl[2].c_str() )-1;
            f.d = (int)atof( tbl[3].c_str() )-1;
            sciana.push_back(f);
            std::cout << "kolejnosc f.a: " << f.a << " f.b: " << f.b << " f.c: " << f.c <<" f.d: " << f.d << std::endl;
        }
        else if( ch == "vn" )
        {
            line >> tmp >> tbl[0] >> tbl[1] >> tbl[2];
            vn.x = atof( tbl[0].c_str() );
            vn.y = atof( tbl[1].c_str() );
            vn.z = atof( tbl[2].c_str() );
            wieszcholki_normalne.push_back(vn);
            std::cout << "normalne v1: " << vn.x << " v2: " << vn.y << " v3: " << vn.z << std::endl;
        }
    }
    rysuj=true;
}

I check it in Visual studio and problem is the same, after comment the rysuj=true, everything is working, pls look at the code, maybe i lose something. rysuj=true makes that it is drawing:

  if(rysuj){
      glColor3f(0.0, 0.0 ,0.0);
    for(int i=0 ; i< sciana.size(); i++){
    glBegin(GL_QUAD_STRIP);
    glNormal3f(wieszcholki_normalne[i].x , wieszcholki_normalne[i].y , wieszcholki_normalne[i].z);
    glVertex3f(wieszcholki[sciana[i].a].x, wieszcholki[sciana[i].a].y,wieszcholki[sciana[i].a].z);
    glNormal3f(wieszcholki_normalne[i].x , wieszcholki_normalne[i].y , wieszcholki_normalne[i].z);
    glVertex3f(wieszcholki[sciana[i].b].x, wieszcholki[sciana[i].b].y,wieszcholki[sciana[i].b].z);
    glNormal3f(wieszcholki_normalne[i].x , wieszcholki_normalne[i].y , wieszcholki_normalne[i].z);
    glVertex3f(wieszcholki[sciana[i].c].x, wieszcholki[sciana[i].c].y,wieszcholki[sciana[i].c].z);
    glNormal3f(wieszcholki_normalne[i].x , wieszcholki_normalne[i].y , wieszcholki_normalne[i].z);
    glVertex3f(wieszcholki[sciana[i].d].x, wieszcholki[sciana[i].d].y,wieszcholki[sciana[i].d].z);
    glEnd();
    }
