Physics and Special Effects
In the traditional first-person point-and-click adventure game, backgrounds were prerendered, and action took place as sprites replacing a small portion of screen to show a 2D animation. Even after 3D-rendered backgrounds took the place of hand-painted backdrops, sprites were still the most typical means of showing the action.
Today, however, with real-time 3D technology getting close enough to prerender quality, the whole game can be produced within the 3D environment. This opens up the possibility of using physics, particle systems, and other physical-based effects to enhance or even replace keyframed ...
