I thought phong shading was something that typically required the GPU to be specifically programmed so it could be applied per pixel...I guess I don't know what it is then.
Yeah, that would look really nice, but, it probably would not be worth it. Built in fog should work fine, plus that helps cut parts of the scene awayAlso I'm looking at some docs concerning real-time volumetric fog - might use this for the clouds...but major framerate hit for this.
