skybox - glTexParameteri

OpenGL OpenGL: Basic Coding
1

hello,

my problem:

  • i can see the edges of my box in black (there are actually 2 / 6 sites in my scene)
  • glext.h is included

my code - port of the textureloader:

    // Typical Texture Generation Using Data From The Bitmap 
    //glBindTexture(GL_TEXTURE_2D, texture[0]); 
    //glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); 
    //glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); 
    glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); 
    glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); 
    glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_R, GL_CLAMP_TO_EDGE); 
    glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MAG_FILTER, GL_LINEAR); 
    glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

part of the drawscene code:

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);    // Clear The Screen And The Depth Buffer 
    glLoadIdentity();                                    // Reset The View 

    glRotatef(r, 0, 1, 0); 

    // http://sidvind.com/wiki/Skybox_tutorial, http://www.youtube.com/watch?v=imCNAWMC1Xs 
    glDisable(GL_DEPTH_TEST); 
    // front 
    glBindTexture(GL_TEXTURE_2D, texture[1]); 
    glBegin(GL_QUADS); 
        glTexCoord2f(0, 0); glVertex3f(  0.5f, -0.5f, -0.5f ); 
        glTexCoord2f(1, 0); glVertex3f( -0.5f, -0.5f, -0.5f ); 
        glTexCoord2f(1, 1); glVertex3f( -0.5f,  0.5f, -0.5f ); 
        glTexCoord2f(0, 1); glVertex3f(  0.5f,  0.5f, -0.5f ); 
    glEnd(); 
    // left 
    // back 
    // right 
    glBindTexture(GL_TEXTURE_2D, texture[2]); 
    glBegin(GL_QUADS); 
        glTexCoord2f(0, 0); glVertex3f( -0.5f, -0.5f, -0.5f ); 
        glTexCoord2f(1, 0); glVertex3f( -0.5f, -0.5f,  0.5f ); 
        glTexCoord2f(1, 1); glVertex3f( -0.5f,  0.5f,  0.5f ); 
        glTexCoord2f(0, 1); glVertex3f( -0.5f,  0.5f, -0.5f ); 
    glEnd(); 
    // top 
    // bottom 
    glEnable(GL_DEPTH_TEST); 

    glTranslatef(lr, 0.0f, ou)

question:

  • why does it not clamp the edges
  • i think it should work so

thanks for your help.
