Voxels, in most voxel engines, <i>are</i> cubes and not points in 3-space. Likewise, in most modern retro-styled pixel art games, the intent really is for the pixels—from the game engine&#x27;s perspective, not the display&#x27;s—to be squares. Often a game&#x27;s pixel is rendered using a square grid of multiple display pixels per engine pixel.
