So whats a pixel then a 0D object. It doesn't extend in any xy
directions.

1D objects = pixels, they don't extend in either xy direction of the
screen.

2D objects = lines, they extend in one of the x or y directions.

3D objects = squares etc, they extend in both x and y directions.

Then again,

1D objects = pixels and lines, they extend in only 1 of the xyz
directions.

2D objects = squares, they extend in 2 of the xyz.

3D objects = cubes etc, they extend in the xyz.


I think it depends on whether your a 2D programmer or a 3D programmer.
 Seeing as the subjects Quake like 3D engine programming I guess lines
are 1D in this context.
