Working on various projects over the years, I’ve often had reason to tinker with 3D graphics rendered using an orthographic projection.
Most first-person 3D games use a perspective projection, which appears generally “realistic,” with objects shrinking as they become more distant. When virtual scenes are rendered this way, we (as humans, with eyeballs) can use our visual intuitions to judge the scale and arrangement of objects within them. That’s the case even when a scene is very abstract, like this one:
I could point to any two cubes in the scene above, ask “which one is closer?” and you’d be able to tell me, instantly and confidently.
There’s another kind of projection, called orthographic, often used in 3D applications where you want the view to be diagrammatic rather than dramatic. (It’s very common in strategy games.) In this projection, objects appear the same size regardless of their distance from the camera. Here’s that same scene —
I could point to any two cubes in the scene above, ask “which one is closer?” and you’d have to pause to figure it out. It’s not impossible; sometimes one cube occludes another, a clear giveaway. But the point is, it takes effort, and, very often, your guess is wrong. (Trust me, as a person who has struggled to debug a video game rendered this way!)
Why do I bring this up?
Browsing Twitter the other day, I once again found myself sucked into a far-off event that truly does not matter, and it occurred to me that social media is an orthographic camera.
Imagine those colorful cubes in the orthographic projection above as tweets: all the same size, taking up the same amount of space on the canvas, even though some are way off in the distance while others brush the virtual camera’s lens. Maybe this is a flavor of context collapse: the standardization of all events, no matter how big or small, delightful or traumatic, to fit the same mashed-together timeline.
Before electronic media, news was attenuated by the friction and delay of transmission and reproduction. When it arrived on your doorstep, a report of a far-off event had an “amplitude” that helped you judge whether or not it mattered to you and/or the world.
That’s not the case with social media, where even tiny, distant events are reproduced “at full size” on your screen. This has been true of electronic media for a long time —
Indeed, working out the relative importance of events was, and is, a big part of what newsrooms do. The front page of a print newspaper was, and is, the tangible result: its allocation of paper and ink to different stories a direct and costly indication of their relative weight.
Two thoughts, then.
First, what would it look like for a social media platform to re-establish perspective? To attenuate the strength of signals over distance —
Second, in the absence of any such attenuation, I think a practical and healthy thing that any user of social media can do when confronted with a free-floating cube of news is ask: how big is this, really? Does it matter to me and my community? Does it, in fact, matter anywhere except the particular place it happened? Sometimes, the answer is absolutely yes, but not always —
P.S. Note that orthographic projection has its uses —
