General / Unable to apply texture on my cube using opengl & sfml

« on: August 29, 2016, 04:24:20 pm »

I want to load a texture on one of my faces on a cube. All the other faces have a specific color that I put on them. The problem is that, when I try to apply the texture, it will not display it. Instead, the last texture used on the cube is being applied.

Here is a code sample :

Engine::Engine() : m_isMovingUp(false), m_isMovingDown(false), m_isMovingLeft(false), m_isMovingRight(false), m_context(24, 8, 4, 3, 3), m_angleX(0), m_angleZ(0), m_mov(3.0f, 3.0f, 3.0f)
{
    //Window settings
    m_win.create(sf::VideoMode(800, 600), "SFML Event and with some OpenGL graphics", sf::Style::Default, m_context);
    m_win.setFramerateLimit(60);

    //Opengl settings
    glEnable(GL_TEXTURE_2D);
    m_textureID = loadTexture("/Data/test.jpg");
 }

void Engine::run()
{
    bool running = true;
    while (running)
    {
        processEvents();
        update();
        render();
    }
}


void Engine::cube()
{
    //glRotated(m_angleX, 1, 0, 0);
    //glRotated(m_angleZ, 0, 0, 1);
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
    glBindTexture(GL_TEXTURE_2D, m_textureID);
    glBegin(GL_QUADS);
    //face Rouge
    //glColor3ub(255, 0, 0);
    glTexCoord2d(0, 1); glVertex3d(1, 1, 1);
    glTexCoord2d(0, 0); glVertex3d(1, 1, -1);
    glTexCoord2d(1, 0); glVertex3d(-1, 1, -1);
    glTexCoord2d(1, 1); glVertex3d(-1, 1, 1);
    glEnd();
    glBegin(GL_QUADS);
    //face verte
    glColor3ub(0, 255, 0);
    glVertex3d(1, -1, 1);
    glVertex3d(1, -1, -1);
    glVertex3d(1, 1, -1);
    glVertex3d(1, 1, 1);

    //face bleu
    glColor3ub(0, 0, 255);
    glVertex3d(1, -1, 1);
    glVertex3d(-1, -1, 1);
    glVertex3d(-1, -1, -1);
    glVertex3d(1, -1, -1);

    //face jaune
    glColor3ub(255, 255, 0);
    glVertex3d(-1, 1, 1);
    glVertex3d(-1, 1, -1);
    glVertex3d(-1, -1, -1);
    glVertex3d(-1, -1, 1);

    //face cyan
    glColor3ub(0, 255, 255);
    glVertex3d(1, 1, -1);
    glVertex3d(1, -1, -1);
    glVertex3d(-1, -1, -1);
    glVertex3d(-1, 1, -1);

   //face magenta
   glColor3ub(255, 0, 255);
   glVertex3d(1, -1, 1);
   glVertex3d(1, 1, 1);
   glVertex3d(-1, 1, 1);
   glVertex3d(-1, -1, 1);

   glEnd();
   glFlush();
}

GLuint Engine::loadTexture(string file)
{
    GLuint textureID;
    if (!m_image.loadFromFile(file))
        EXIT_FAILURE;
    glGenTextures(1, &textureID);
    //glBindTexture(GL_TEXTURE_2D, textureID);
    glTexImage2D(GL_TEXTURE_2D, 0, 4, m_image.getSize().x, m_image.getSize().y, 0, GL_RGBA, GL_UNSIGNED_BYTE, m_image.getPixelsPtr());
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

    return textureID;
}

This is where I'm at after fixing as much as I could.



thanks for your help !

PS: Since he is not able to apply the texture, the face is automaticly painting in pink since it is the last call with Glcolor
