"Two and a half-D" is an optimization trick for [[RT3D]] that fakes the [[Viewer<sup>1</sup>|viewer]] into thinking they are seeing true 3D graphics. A whole scene (or an object in a scene) is made of 2-dimensional graphics that are scaled and drawn in perspective to look like [[Polygon|polygonal]] graphics, but there are no polygons involved. The groundbreaking game Doom is built entirely on this concept. [[Billboard|Billboards]] are 2.5D, but [[Voxels|voxels]] can be either 2.5D or 3D.
