Not sure if this is an advanced topic but here goes:
What is the correct way to implement a skybox?
Take a look at the following picture: http://www.cornflakezone.com/gallery.php?galleryitem=14
notice the sky has a visible corner in the center of the screen? What am I doing wrong?
The sky in this case is a dome shape, like the inside of a breakfast bowl. I disable the Depth test and draw it first before everything else, It's also quite large, huge in fact compared to the models.
I've also seen people use a flat sky which is parallel to the ground and box in the sides at 90 degrees to one another but again I get the corners. I know someone can help me, I just never figured this simple thing out. There's some trick I'm missing...
