Fixed 3D
From Wikipedia, the free encyclopedia
In techniques for computer games, fixed 3D is a three-dimensional (3D) representation of the game world with game characters rendered in real time against a prerendered environment.
Used heavily in the survival horror game genre, it was first seen in Infogrames' Alone in the Dark series in the early 1990s; it was later revived and brought up to date by Capcom in the Resident Evil (series).
Other notable examples include:
- Little Big Adventure (Adeline Software International)
- Final Fantasy VII (Squaresoft)
- The first 3 installments of the Mario Party series (Nintendo)
- Blade Runner (Westwood Studios) - apparently the backgrounds are rendered in real time, using millions of polygons, although this is difficult to tell
- Ecstatica and Ecstatica 2 (Andrew Spencer/Psygnosis) - unusual in that the backgrounds and characters are rendered with ellipsoids, leading to a very natural looking set of creatures. Like Blade Runner, it again is rendered entirely in real time, although it is difficult to tell at first sight
- The Legend of Zelda: Ocarina of Time (Nintendo) was mostly complete 3D but used fixed 3D is used for many of the building interiors and for one entire town. This technique was dropped for complete 3D in its successor, The Legend of Zelda: Majora's Mask,
- Grim Fandango (Lucasarts)
- 3D Movie Maker (Microsoft Kids) featured several premade sets rendered in Fixed 3d, but also allowed for users to create their own Real-time scenery.
Admittedly, there seems little to separate fixed 3D from its precursor, the graphic adventure game (The Secret of Monkey Island, Sam & Max Hit the Road, etc.), but whereas the latter overlays 2D characters over a 2D background, fixed 3D is at least 3D overlaid on 2D, and often onto 3D.
