Texture the inside of a quad?

OpenGL OpenGL: Basic Coding

In my application I am making a box to go around my world as a skybox. The only problem is, I cannot see it from inside the box. Only from the outside. To draw it I am using GL_QUADS.

The code to draw the box is:

 
	glPushMatrix();
	glBegin(GL_QUADS);
    glVertex3f( 256.0f, 256.0f, 256.0f);   
    glVertex3f( 256.0f,-256.0f, 256.0f);  
    glVertex3f( 256.0f,-256.0f,-256.0f);  
    glVertex3f( 256.0f, 256.0f,-256.0f); 

    glVertex3f( 256.0f, 256.0f,-256.0f);   
    glVertex3f( 256.0f,-256.0f,-256.0f);   
    glVertex3f(-256.0f,-256.0f,-256.0f);  
    glVertex3f(-256.0f, 256.0f,-256.0f);   

    glVertex3f(-256.0f, 256.0f,-256.0f);   
    glVertex3f(-256.0f,-256.0f,-256.0f);   
    glVertex3f(-256.0f,-256.0f, 256.0f);   
    glVertex3f(-256.0f, 256.0f, 256.0f);   

    glVertex3f(-256.0f, 256.0f, 256.0f);   
    glVertex3f(-256.0f,-256.0f, 256.0f);  
    glVertex3f( 256.0f,-256.0f, 256.0f);  
    glVertex3f( 256.0f, 256.0f, 256.0f);   

    glVertex3f(-256.0f, 256.0f,-256.0f);  
    glVertex3f(-256.0f, 256.0f, 256.0f);  
    glVertex3f( 256.0f, 256.0f, 256.0f);   
    glVertex3f( 256.0f, 256.0f,-256.0f);   

    glVertex3f(-256.0f,-256.0f, 256.0f);   
    glVertex3f(-256.0f,-256.0f,-256.0f);  
    glVertex3f( 256.0f,-256.0f,-256.0f);   
    glVertex3f( 256.0f,-256.0f, 256.0f);   
	glEnd();
	glPopMatrix();

The code to texture it is:

 
glBindTexture(GL_TEXTURE_2D, texture[4]);

I call that just before I call the function to draw the cube. And I know that code is working because I use it on all my other textured items. I just need to get it to texture the inside of the box :frowning:

Don’t worry. I figured it out. I disabled the culling just before it drew the box, and it is working fine now.

You could have kept the face culling enabled if you sent the quads’ vertices reordered so that the faces’ front points to the inside.
