Tweak3D ha pubblicato un'approfondita analisi tecnica del chipset NVidia NV20, sopratutto per quanto riguarda i Pixel e Vertex Shaders programmabili. La trovate a questo indirizzo

What is per-pixel shading? It's a method of applying special rendering effects... per pixel. It allows material and real world effects to be applied individually to a pixel for more accuracy and intensity. Per-pixel shading will redefine the visual look and feel of imagery for PC graphics. Per-pixel shading has long been used in film production to create a more realistic and lifelike appearance for computer generated imagery. If you've seen Toy Story, you'll definitely remember Buzz Light-year. Remember the translucent reflection on Buzz's helmet? How the environment and light streaks reflected off the glass but also let the image underneath show through? That was done with per-pixel shading. Until now, it wasn't practical to use per-pixel shading on a PC because of the intense power and processing requirements needed. Sure, you could have done that in 3D Studio but could you have done it in real-time? Could the effect be applied to an entire frame at high resolution in 1/60th of a second? Not until now.
