25. Normalized device space

1. all four coordinates (x, y, z, w) are divided by w

   • z is translated into the range between 0.0 and 0.1

   • w is set to 1.0. The result is considered to be the normalized device space, or screen space:

   
       -1.0 <= x <= +1.0
       -1.0 <= y <= +1.0
        0.0 <= z <= +1.0
               w = 1.0
   
   

2. Everything inside the NDC space is shown on screen.
