openGL and Textures

Name: Anonymous 2010-11-13 14:52

So /anus/, I've been reading tutorials on openGL and how to render textures to the screen, but whenever i try all i get is a black box
here is my texture loading code

GLuint LoadTexture(const char *filename)
{
    GLuint texture = FALSE;

    /* Create storage space for the texture */
    SDL_Surface *TextureImage[1];

    /* Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit */
    if ( ( TextureImage[0] = IMG_Load(    filename ) ) )
    {
            /* Create The Texture */
            glGenTextures( 1, &texture );
           
            /* Load in texture 1 */
            /* Typical Texture Generation Using Data From The Bitmap */
            glBindTexture( GL_TEXTURE_2D, texture);
           
           
            //create the image
            glTexImage2D(GL_TEXTURE_2D,
                         0,
                         4,                    //alpha enabled
                         TextureImage[0]->w,
                         TextureImage[0]->h,
                         0,
                         GL_RGBA,            //HERP
                         GL_UNSIGNED_BYTE,
                         TextureImage[0]->pixels);

            /* Nearest Filtering */
            glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR );
            glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST );
    }

    /* Free up any memory we may have used */
    if ( TextureImage[0] )
        SDL_FreeSurface( TextureImage[0] );

    return texture;
}


and the render code:

glMatrixMode (GL_PROJECTION);
glLoadIdentity ();
glOrtho (0, SCREEN_WIDTH, SCREEN_HEIGHT, 0, 0, 1);
glMatrixMode (GL_MODELVIEW);
glLoadIdentity();

/* Clear The Screen And The Depth Buffer */
glClearColor(1.0f,1.0f,1.0f,0.0f); //white
glClear( GL_COLOR_BUFFER_BIT );

glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D,anus);
glBegin(GL_QUADS);
    glTexCoord2d(0.0,0.0); glVertex2d(50.0,50.0);
    glTexCoord2d(1.0,0.0); glVertex2d(90.0,50.0);
    glTexCoord2d(1.0,1.0); glVertex2d(90.0,90.0);
    glTexCoord2d(0.0,1.0); glVertex2d(50.0,90.0);
glEnd();


glPushMatrix();
glMatrixMode(GL_PROJECTION);
glPushMatrix();

I find it funny that people go around touting OpenGL 2.x as deprecated when 3.x is only supported by ~40% of users per the Steam hardware survey, and 4.x is supported by maybe two graphics cards total.
