Definitions for "Perspective correction"
In this mode, the textures are applied taking care of the perspective variations from the observer point of view.
The technique of applying a texture map to a polygon that is angled away from the camera, interpolating so that the texture is stretched onto the polygon appropriately for the apparent depth of the polygon. Direct3D supplies perspective correction automatically.
Adjusting textures so that they converge correctly with distance, giving them a more realistic appearance when viewed from various angles.
Triangles which recede into the distance (like a road to the horizon) are recalculated to make them appear smaller as they recede.
Perspective correction or perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective.
