2.5D

What is a 2.5D object showing a 2D, 2.5D and true 3D object

A 2.5D shape is three-dimensional, but the use of the third dimension, usually height, is limited to simple top-down operations. I learned about 2.5D, or two and a half dimensions, from my engineering days.

It turns out it’s really quite common to make 2.5D things because, for example, it’s easy to drill or mill down into something, and it's a pain to turn something on its side and drill from the other side. Or, as with vacuum forming, it’s easy to suck plastic onto a mold but a pain to get it off if you’ve got any overhangs as you can’t lift it straight up again. Hence, the plastic sandpit in our garden is a 2.5D object rather than true 3D.

As we become more sophisticated at making things, more objects will be true 3D rather than 2.5D. But the simple two-and-a-half-dimensional option is still generally cheaper and easier and will not disappear soon.

Civilization, in general, looks rather 2.5D from the air as we tend to build upwards, but we don’t find overhangs that easy or practical, thanks also to gravity, e.g., the Pyramids.

The Writer's in the Writing. The Artist's in the Art.

Orthographic projection

Every creation is a mirror, reflecting something of its creator. If you and I were to paint the same subject, your painting would reflect some of you, and mine would reflect some of me. If we both write stories, each one will carry something of ourselves—our personality, our experiences. The writer is in the writing. The artist is in the art. The musician's in the music. Take writing as an example. If we're writing authentically, we can't help but share a bit of ourselves in our work. Our past experiences affect what we notice. Our timidity or confidence is reflected in the tone and style. Our education in the choice of words. Our kindness and patience, or cynicism and frustration, is revealed to the reader. And the choice of what you write or paint reflects you. Not if we're trying too hard. Not if we're writing to sound like a writer or if we're adopting a "literary" style because we think that's how it should be done. And not if we focus more on pleasing a search engine or ticking off marketing goals than connecting with readers. But if we write honestly and directly, the writer shows through. The Third Dimension This phrasing hit me while reading Brenda Ueland's book If You Want to Write. She calls the writer the Third Dimension. I believe she means that when you read a book, there are the characters, the reader, and also, inescapably, the writer's personality. She writes that readers can tell when writing isn't authentic, when it's not really you, but instead, a performance to meet someone else's expectations of how one should write—or perhaps a creation of an AI's sycophantic personality. The presence of the writer in the writing, or the artist in the art, leads Ueland to say, "…I have come to think the only way to become a better writer is to become a better person." I believe this principle also holds true across other creative disciplines, though I thought "the cook is in the cooking" didn't quite have the same ring. Still, it holds a ring of truth if I consider a musician and their music, an entrepreneur and their business, a podcaster and their podcast and others. It's hard to write this without wondering what I'm sharing about myself (and what gets scrubbed out and cleansed by Grammarly proofreading). In Sketchplanations as a project, I've come to think that sooner or later, everything I know of value will be there. So, in some way, the whole thing reflects me. Shall we go for a beer?
