2.5D Perspective

« Glossary Index

2.5D (“two-and-a-half-dimensional”), 3/4 perspective and pseudo-3D are terms, mainly in the video game industry, used to describe either:

  • 2D graphical projections and techniques which cause a series of images or scenes to fake or appear to be three-dimensional (3D) when in fact they are not, or
  • Gameplay in an otherwise three-dimensional video game that is restricted to a two-dimensional plane.

Common in video games, these projections have also been useful in geographic visualization (GVIS) to help understand visual-cognitive spatial representations or 3D visualization.

The terms 3/4 perspective and 3/4 view trace their origins to portraiture and facial recognition, where they are used to describe a view of a person’s face which is partway between a frontal view and a side view.
