Does Splinter Cell use per-pixel lighting?

[Luminescent]

Splinter seems to use some sort of real-time, scan-line rendering based, global lighting model. I just wanted to know if the lighting calculations (aside from the normal/bump maps) were being performed at the pixel level. Does anyone know?

oh I'm certian it's per-pixel yes...

Diffuse lighting is per-vertex. They use maps for local lights and shadows which can be considered per-pixel.

Cybamerc, is such a lighting model intense on the hardware in any way?

 

[cybamerc]

I won't speculate on that but certainly lighting and shadowing is something that has been expanded and improved on over the core Unreal tech.

The lighting math for the lightmaps is precalculated, so there is no intense pixel-combiner math, right? Just curious.

Yes, as far as I know, they do most of the lighting & shadowing with hacks & tricks (Sweeney talked about that in an interview to GameSpy), so it's not like DOOM III, where everything is unified.

Like alexsok said, they use a variety of different methods for shadows, mostly its a mix of pre-caculated shadow maps like all the Unreal games, but also projectors like the new UT and real-time calculated shadow maps for individual light-sources, those look the most impressive actually IMHO.
alexsok, not being a unified lighting model doesn't mean it can't be per-pixel though AFAIK, or does using real-time shadow mapping and other methods instead of stencil shadows automatically imply its not per-pixel? I don't think so but please someone correct me if I'm wrong...
