![]() This illusion is only possible due to the equally foreshortened axes of an isometric projection. However, because all axes meet at equal angles, isometry is often easier to draw and also allows for interesting illustrative possibilities, including optical illusions like one found on this Swedish postage stamp: See these three different projections of the same desk: In fact, non-isometric renderings often look more natural to many viewers as they cause less distortion to the “front” face of an object. It is quite common to represent 3D objects using projections in which these angles are not equal. When the axes of height, width, and depth meet, the angles formed are all equal (120 degrees), like so:Īll this is in the word: iso meaning “equal” and metric meaning “measurement”. Isometric Projection is special because every dimension is equally foreshortened. In fact, even if you draw just a square to represent a cube, you’re still using Orthographic Projection, which repesresents just one side of a 3D object at a time. Every time you draw a cube as something more than just a square on your page, you’re using a form of projection. A projection is simply a method of representing a 3D object in 2D space, used everywhere from Renaissance perspective painting to architectural modeling software. “Isometic” is a style of graphical projection. What does this mean? Let’s break it down! But here we go with a little something the gra phic designer/illustrator in me thinks is really neat. Neither of these is conducive to getting a blog entry done. I seem to go through alternating cycles of being either extremely busy or extremely lazy.
