Texture Binding : OpenGL + OpenCV

Question

I am trying to read an image from a file and map it as openGL texture. OpenCV is reading the image right and showing it in a window created from there. but the texture mapping part is not working. Can't find out why. My code is given below:

int InitGL(GLvoid){

    try
    {
        Mat img = imread("aaa.jpg", CV_LOAD_IMAGE_ANYDEPTH);
        if (&img != NULL)
        {
            namedWindow("Show Image", CV_WINDOW_AUTOSIZE);
            imshow("Show Image", img);
        }
        glGenTextures(1, texture);
        glBindTexture(GL_TEXTURE_2D, texture[0]);
        glTexImage2D(GL_TEXTURE_2D, 0, 3, img.cols, img.rows, 0, GL_RGB, GL_UNSIGNED_BYTE, img.data);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
        img.release();
    }
    catch (Exception e)
    {
        cout << "My Msg: " +e.msg << endl;
    }

    glEnable(GL_TEXTURE_2D);
    glShadeModel(GL_SMOOTH);               // enabling smooth shader
    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);  // black background

    glClearDepth(1.0f);                    // depth buffer setup
    glEnable(GL_DEPTH_TEST);               // enable depth testing
    glDepthFunc(GL_LEQUAL);                // the type of depth test to do

    glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);     
    return TRUE;                           // initialization went ok
}

int DrawGLScene(GLvoid){


    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);         // Clear The Screen And The Depth Buffer
    glLoadIdentity();
    glTranslatef(0.0f, 0.0f, -6.0f);                   // Move Right 3 Units
    glRotatef(rotationQuad, 1.0f, 0.0f, 0.0f);
    glBindTexture(GL_TEXTURE_2D, texture[0]);
    glBegin(GL_QUADS);
        // Front Face
        glTexCoord2f(0.0f, 0.0f); glVertex3f(-1.0f, -1.0f, 1.0f);  // Bottom Left Of The Texture and Quad
        glTexCoord2f(1.0f, 0.0f); glVertex3f(1.0f, -1.0f, 1.0f);  // Bottom Right Of The Texture and Quad
        glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, 1.0f, 1.0f);  // Top Right Of The Texture and Quad
        glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f, 1.0f, 1.0f);  // Top Left Of The Texture and Quad
        // Back Face
        glTexCoord2f(1.0f, 0.0f); glVertex3f(-1.0f, -1.0f, -1.0f);  // Bottom Right Of The Texture and Quad
        glTexCoord2f(1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, -1.0f);  // Top Right Of The Texture and Quad
        glTexCoord2f(0.0f, 1.0f); glVertex3f(1.0f, 1.0f, -1.0f);  // Top Left Of The Texture and Quad
        glTexCoord2f(0.0f, 0.0f); glVertex3f(1.0f, -1.0f, -1.0f);  // Bottom Left Of The Texture and Quad
        // Top Face
        glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f, 1.0f, -1.0f);  // Top Left Of The Texture and Quad
        glTexCoord2f(0.0f, 0.0f); glVertex3f(-1.0f, 1.0f, 1.0f);  // Bottom Left Of The Texture and Quad
        glTexCoord2f(1.0f, 0.0f); glVertex3f(1.0f, 1.0f, 1.0f);  // Bottom Right Of The Texture and Quad
        glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, 1.0f, -1.0f);  // Top Right Of The Texture and Quad
        // Bottom Face
        glTexCoord2f(1.0f, 1.0f); glVertex3f(-1.0f, -1.0f, -1.0f);  // Top Right Of The Texture and Quad
        glTexCoord2f(0.0f, 1.0f); glVertex3f(1.0f, -1.0f, -1.0f);  // Top Left Of The Texture and Quad
        glTexCoord2f(0.0f, 0.0f); glVertex3f(1.0f, -1.0f, 1.0f);  // Bottom Left Of The Texture and Quad
        glTexCoord2f(1.0f, 0.0f); glVertex3f(-1.0f, -1.0f, 1.0f);  // Bottom Right Of The Texture and Quad
    // Right face
        glTexCoord2f(1.0f, 0.0f); glVertex3f(1.0f, -1.0f, -1.0f);  // Bottom Right Of The Texture and Quad
        glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, 1.0f, -1.0f);  // Top Right Of The Texture and Quad
        glTexCoord2f(0.0f, 1.0f); glVertex3f(1.0f, 1.0f, 1.0f);  // Top Left Of The Texture and Quad
        glTexCoord2f(0.0f, 0.0f); glVertex3f(1.0f, -1.0f, 1.0f);  // Bottom Left Of The Texture and Quad
    // Left Face
        glTexCoord2f(0.0f, 0.0f); glVertex3f(-1.0f, -1.0f, -1.0f);  // Bottom Left Of The Texture and Quad
        glTexCoord2f(1.0f, 0.0f); glVertex3f(-1.0f, -1.0f, 1.0f);  // Bottom Right Of The Texture and Quad
        glTexCoord2f(1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, 1.0f);  // Top Right Of The Texture and Quad
        glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f, 1.0f, -1.0f);  // Top Left Of The Texture and Quad
    glEnd();                           // Done Drawing The Quad

    rotationQuad -= 0.15f;
    return TRUE;                                 // Everything Went OK
}

The window created from OpenCV is showing the image. It is for debugging and testing whether the image is read correctly or not. The cube was supposd to be textured. But it is not showing any texture on it.

Answer 1

Using:
glGenTextures(1, &texture[0]);
instead of:
glGenTexures(1, texture);
solved it.
