Top-Down Perspective

Revision as of 18:10, 22 February 2009 by ZS (talk | contribs) (→‎Extent of use)

Top-down perspective was a prominent camera view used in the Grand Theft Auto series, where the player and their surrounding is viewed overhead. Its use in the series is short-lived, having been the defacto camera view in GTA1 and GTA2, only to decline in importance as one of several alternate camera views in GTA III and be removed entirely in GTA: Vice City. The view has only been feature twice thereafter.

Description

Adopted in both GTA1 and GTA2 as the only camera angle in game, the view simply depicts the player and their surrounding from a bird's eye view, directly over the player at a considerable height. The camera system adjusts its height from the player according to the movement and position of the player, relative to the speed in which the player travels. When on foot, the camera draws closer to the player, reducing the player's line of sight as the player moves slower. When inside a vehicle, however, the camera moves further up, and some more when the vehicle's speed increases. Top-down perspective has the disadvantage of a limited line in sight, rendering speedy travel somewhat difficult as the player has little room to foresee the traffic ahead; this, coupled with the lack of camera orientation, made navigation and aiming difficult.

The use of top-down perspective by early GTA games was complemented by the use of a 3D engine that permits the ability to render a portion of a large city as seen overhead, albeit with limited flexibility on city design. The height of buildings and structures are restricted to a certain height, while long underground roadways could not be effectively included unless they are used by trains or partially exposed, as the player will not be able to see underground traffic. Gradients, however, are permit in top-down perspective, allowing the player to perform jumps off high areas or ramps. Height in a top-down perspective was also used in GTA2 to comical effect to exaggerate the effects of explosions on people; certain individuals would be flung high enough by a blast that they pass the camera, before falling to their deaths.

Extent of use

Top-down perspective was evidently featured in GTA1 and GTA2, but fell out of use when GTA III introduced an improved graphics engine and freeform camera view that enabled players to better move around and explore the environment. GTA III retained top-down perspective as a camera option, but as an alternate view. A year later, the view was dropped in GTA: Vice City.

Only two titles since GTA III have featured top-down perspective as a camera option. GTA Advance, developed by Digital Eclipse, opted for top-down perspective as its camera view due to hardware limitations on the Game Boy Advance. The PC version of GTA IV also features an "overhead" view as one of its camera views on its Video Editor, but does not adopt it in actual gameplay.
