[drawing every day post seven]: gotta hand it to you

centaur 0

If you want to get better at drawing, you really need to treat it like any other skill, and practice ahead of your performance. We may learn by doing, but you don't get enough learning time or variety just from actually performing the task. Basketball players need to cross-train in addition to shooting hoops - not just play games. Chess masters practice with coaches. Writers scribble in their notebooks. And artists sketch.

My horse drawing book was too big to fit in my bookbag, so today's exercise is from the cover of Drawing Hands and Feet by Ken Goldman.

More practice from Foster's book. I was shy on time, so I didn't start with the proportions diagram, but with the parts diagram, and therefore the proportions of my parts are a bit off. But, it's a step.

[drawing every day 2024 post five]: a third pony trick

centaur 0

Well, logically speaking, if I want to "plan for success" in my art, and I've drawn a centauress with some hooves that I don't like, I should focus on getting better at drawing hooves. From Foster's "Drawing Horses" book, sketched in my little "One Trick Pony" sketchbook.

P.S. I am totes going back and renaming the last art post "a second pony trick".

[twenty twenty four day five]: plan for success, but for art

centaur 0

One of the productivity tools I use is a technique called "plan for success." I mostly use it for todo lists, and for that topic it's worth a blog post of its own, but, briefly, when taking on a task, I like to start off with a "plan for success" sheet where I list:

  • What the project is (e.g, going to Dragon Con)
  • Where I currently am on the project (e.g, about to leave, just arrived)
  • What the context of the next work block is (the next 4-5 days, or the next month)
  • What success would look like (e.g., attend all my panels, meet all my friends, hit the dealer's room)

Once I have that, I start listing todo items, then categorizing them into the four Stephen Covey quadrants - Urgent and Important, Not Urgent yet Important, Urgent yet Unimportant, and Not Urgent and Not Important. Making sure that the "Not Urgent yet Important" stuff gets done is the hardest part, so I usually tranche the TODOs into "do immediately, do today, do before I leave".

But the whole "plan for success" idea came from an artist - I don't remember who - talking about the difference between professionals and amateurs. An amateur may produce great art, they said, but on accident, even if they're skilled, because they don't know how they're doing what they're doing. A professional, on the other hand, makes a plan to ensure that their art piece succeeds. They may not always succeed at it - plenty of professional artists have to start pieces over - but they don't paint themselves into a metaphorical corner as much because they've taken steps to ensure the piece comes out well - for example, by getting reference art, doing perspective or construction lines, or practice drawings.

I wonder if this idea also works for learning art? Let's find out.

[drawing every day 2024 post four]: tricking the pony again

centaur 0

Let's see you do that, ChatGPT / DALL-E! Wait, what happens if we try it?

Ha-ha! Three strikes, you're out! (ChatGPT tried and failed three times to generate this image). DALL-E may be a better renderer than me, but it isn't better at imagining the things that I want to imagine.

No plans on giving up drawing soon.

-the Centaur

P.S. This is Porsche the Centaur again, this time with construction lines drawn in pencil, later erased. The upside-down nature made it hard to get the hooves right, and I didn't want to re-draw it, so it could have come out better. But! It went much faster practicing in the smaller "One Trick Pony" notebook. Onward!

[twenty twenty four day four]: there’s some problems on that boat

centaur 0

Okay, I'm going to start out with the best of the images that I produced trying to create Porsche the Centaur using ChatGPT's DALL-E interface. The above is ... almost Porsche, though her ears are too high (centaurs in the Alliance universe have ears a little more like an elf, but mobile like a dog's). And, after some coaxing, the ChatGPT / DALL-E hybrid managed to produce a halfway decent character sheet:

But both of these images came after several tries. And when I tried to get ChatGPT / DALL-E to generate a front and back view of the same character sheet, it just disintegrated into random horse and human parts:

Similarly, the initial centaur image came only after many prompt tweaks and false starts, like this one:

There are legitimate questions about whether the current round of AI art generators were trained on data taken without permission (they almost certainly were), whether they could displace human artists (they almost certainly will), and whether they will have destructive effects on human creativity (the jury is out on this one, as some forms of art will wane while new forms of art will wax).

But never let anyone tell you they've worked out all the bugs yet. These systems are great renderers at the image patch level, but their notion of coherence leaves a lot to be desired, and their lack of structural knowledge means their ability to creatively combine is radically limited to surface stylistics.

One day we'll get there. But it will take a lot of work.

P.S. I apparently was wrong: I thought I had kept up Drawing Every Day for 103 days in 2021, but actually it was 205 days that started in late, late 2020, with a brief spurt in 2023. So this is the third time I've tried it! Best of luck Dr. Francis on beating your past winning streak.

[seventy-seven] minus eighty-three: mondrian cat

centaur 0

Just Loki, on the back patio, looking at a leaf ... with a little added magic (full size).

Producing this relatively simple image actually involved a fair number of Photoshop tools, several of which are new "generative AI" tools, but many others of which are just plain old machine vision magic:

  • Layers (stacked images) used extensively to save original or alternate versions of things.
  • Perspective Warp (a pretty impressive tool in its own right) to distort the image into a rectilinear shape.
  • Content Aware Fill (a new Photoshop generative AI tool) to extend the warped stone tile to fill the frame.
  • The Clone Stamp tool to complete the grout lines which were only partially filled in by Content Aware Fill.
  • Quick Selection tool to isolate Loki and the leaf into their own layers for later.
  • Selection > Modify > Expand and Selection > Modify > Feather to get the fine hairs on Loki's boundary.
  • Generative Fill (another generative AI tool) to eliminate many of the leaves.
  • More Clone Stamp to eliminate more leaves and minor imperfections.
  • Layer duplication to create an original and to-be-colored tile backdrop.
  • Swatches, the Rectangular Marquee tool, the Polygonal Lasso, and the Fill tool to create the colored tile.
  • Color Burn layer blend mode (with 57% opacity) to create the primary Mondrian effect.
  • Another layer duplication to create a new version of the colored tile to enhance the grout.
  • Filter Gallery > Colored Pencil which fortuitously greyed out the colored tile and colorized the grout.
  • Magic Wand tool set to Contiguous and 0% Tolerance to cut out the greyed tiles from the grout layer.
  • Darker Color layer blend mode to enhance the grout.
  • Drop Shadow on the leaf to make it stand out.
  • Duplicating Loki into a layer with Darken to make him stand out against the colored grout.
  • Adding Inner Glow modified to Darken as well (with a Choke of 14 and Size of 87) to eliminate some of the white halo around Loki.
  • Adding a second Loki layer, Normal blend with 50% opacity, to get his sheen.

I like how it came out, especially given how it started:

I looked at that and thought, "You know, that's almost a Mondrian backdrop" and I was right!

[sixty-nine] minus fifty-nine: ai can serve up some creepy

centaur 0

I still have misgivings about using AI-generated art to create final designs without human intervention, and I think AI art needs to address the copyright issue in a meaningful way, but speaking as an artist into cosmic horror, it sure can create some creepy images that are great food for thought. Here's a couple of cool ones from a recent project that I've been working on - great design concepts, whether or not they get used.

Bonus points if you can guess which work this art is designed to illustrate.

[forty-nine] minus twenty: about that midjourney

centaur 0

SO, one of my favorite characters is Porsche, a centauress warrior from the thirty-first century who populated many of my first tranche of as-yet-unpublished science fiction stories. (I think she only appears in one published story, "Stranded" in the anthology of the same name, and even that, just as a cameo). And while I have worked a lot to improve my art, I wondered what Midjourney could do. And I got the above result from the following prompt:

a centauress with long, rich curly purple hair, very beautiful, with half-asian, half-english appearance, and pointed ears, wearing an armored space costume like a combination of ghost in the shell and star trek, and bearing a double-bladed scythe with black glowing blades

- the Centaur

Wow. This is really spot on. Her hair is right, her face is right, her skin tone is right, her armor is right ... heck, even her slightly haunted look is right, and to go beyond even that, one of the variants looks like a slightly older, more grizzled variant, which completely checks out with her storyline:

Kudos to you, Midjourney, except ... she's not a centauress. She's just a person, a fetching one, I admit, but not a half-woman, half-horse creature with the pointed ears and black twin-bladed scythe of the prompt.

Well, shoot. What if we look at some of the other variants?

This one is creepily good in a sense ... it's got her forehead dot (she's a First Contact Engineer, and wears a pheromone bead she used to communicate with a scent-based alien hive species) and even hints of her mechanical arm and possibly ear. But this is just coincidence. Look at this other variant:

What appears is just chance. Here, her ears are rounded, the dot's gone, and the weapon looks even less on point. A lot of what looked right to me is just random features onto which I was projecting, like cloudbusting.

Well, double shoot. What if we refine the prompt? What do we get?

a centauress (a creature with the upper body of a woman and a lower body of a horse) with long, rich curly purple hair, very beautiful, with half-asian, half-english appearance, and pointed ears, wearing an armored space costume like a combination of ghost in the shell and star trek, and wielding a scythe with black glowing blades

- the Centaur

Yerk. That's ... just jumbled nonsense. Tweaks to the prompt to make it simpler just produced women on horses. Midjourney does not apparently understand the concept 'centaur' in any meaningful sense. I tried just the prompt "centaur", and ... um ... yeah ... no, I'm not going to show you those. They're just a guy with a horse, or sort of on a horse, or ... sort of ... in a horse? A centaur as envisioned by The Thing.

Okay, one last try. What if I give it one of my pieces of art, and then ask it to render it anime style? Let's hold that piece of imagery till the last, but the prompt is:

an anime style centauress with purple hair and a double-bladed scythe jumping in front of a waterfall

--the Centaur

Oh, lordy. And I'm not going to show you the one it tried to generate from the prompt "anime style".

Oh wait, I am!

Wow. Evocative - the top left reminds me of Cinnamon Frost - but it has little to do with the image I put in, and the attempt in the top right especially is nonsensical.

I am inspired by Midjourney. It's definitely a better renderer than me, and has good ideas about composition which I have already used in my artwork.

But I stick by my comment that it is an amateur which has taught itself to render very well, and cannot take meaningful art direction. As limited as I am, I'll stick with my own drawing, thank you!

Like this one, the image I gave to Midjourney above. It's not perfect, it's not well rendered ... but it is mine:

Porsche and the Scythe at the Waterfall, Colored

And she has four legs, a scythe, and pointy ears, dag nabit.

[forty-seven] minus twenty-one: i hear there’s a new ai hotness

SO automatic image generation is a controversial thing I think about a lot. Perhaps I should comment on it sometime. Regardless, I thought I'd show off the challenges that come from using this technology using a simple example. If you recall, I did a recent post with a warped bookstore picture, and attempted to regenerate it using generative AI with Midjourney. Unfortunately, the prompt

a magical three-dimensional impossible bookstore in the style of M.C. Escher

me

failed to pick up the image for some reason. After a few iterations with the Midjourney Discord interface, I got the very nice, but nonsensical and generic, AI generated image you see up top. After playing around with the API, I realized that I likely had formulated my prompt wrong, and tried again to include this image:

On the second pass, I got another, more on-point, yet still nonsensical image as you see below:

These systems do LOOK impressive. But they work like ... amateurs who've learned to render well. They can produce things that are cool, but it's very hard to make them produce something on point.

And this is above and beyond the massive copyright issues that arise from a system that regurgitates other people's copyrighted art, much less the impact on jobs, much less the impact on the human soul.

branson in spaaace

Congratulations, Sir Richard Branson, on your successful space flight! (Yes, yes, I *know* it's technically just upper atmosphere, I *know* there's no path to orbit (yet) but can we give the man some credit for an awesome achievement?) And I look forward to Jeff Bezos making a similar flight later this month.

Now, I stand by my earlier statement: the way you guys are doing this, a race, is going to get someone killed, perhaps one of you guys. A rocketship is not a racecar, and moves into realms of physics where we do not have good human intuition. Please, all y'all, take it easy, and get it right.

That being said, congratulations on being the first human being to put themselves into space as part of a rocket program that they themselves set in motion. That's an amazing achievement, no-one can ever take that away from you, and maybe that's why you look so damn happy. Enjoy it!

P.S. And day 198, though I'll do an analysis of the drawing at a later time.

RIP Jeff Bezos (and/or Richard Branson)

centaur 0
rip jeff bezos

You know, Jeff Bezos isn’t likely to die when he flies July 20th. And Richard Branson isn’t likely to die when he takes off at 9am July 11th (tomorrow morning, as I write this). But the irresponsible race these fools have placed them in will eventually get somebody killed, as surely as Elon Musk’s attempt to build self-driving cars with cameras rather than lidar was doomed to (a) kill someone and (b) fail. It’s just, this time, I want to be caught on record saying I think this is hugely dangerous, rather than grumbling about it to my machine learning brethren.

Whether or not a spacecraft is ready to launch is not a matter of will; it’s a matter of natural fact. This is actually the same as many other business ventures: whether we’re deciding to create a multibillion-dollar battery factory or simply open a Starbucks, our determination to make it succeed has far less to do with its success than the realities of the market—and its physical situation. Either the market is there to support it, and the machinery will work, or it won’t.

But with normal business ventures, we’ve got a lot of intuition, and a lot of cushion. Even if you aren’t Elon Musk, you kind of instinctively know that you can’t build a battery factory before your engineering team has decided what kind of battery you need to build, and even if your factory goes bust, you can re-sell the land or the building. Even if you aren't Howard Schultz, you instinctively know it's smarter to build a Starbucks on a busy corner rather than the middle of nowhere, and even if your Starbucks goes under, it won't explode and take you out with it.

But if your rocket explodes, you can't re-sell the broken parts, and it might very well take you out with it. Our intuitions do not serve us well when building rockets or airships, because they're not simple things operating in human-scaled regions of physics, and we don't have a lot of cushion with rockets or self-driving cars, because they're machinery that can kill you, even if you've convinced yourself otherwise.

The reasons behind the likelihood of failure are manyfold here, and worth digging into in greater depth; but briefly, they include:

  • The Paradox of the Director's Foot, where a leader's authority over safety personnel - and their personal willingness to take on risk - ends up short-circuiting safety protocols and causing accidents. This actually happened to me personally when two directors in a row had a robot run over their foot at a demonstration, and my eagle-eyed manager recognized that both of them had stepped into the safety enclosure to question the demonstrating engineer, forcing the safety engineer to take over audience questions - and all three took their eyes off the robot. Shoe leather degradation then ensued, for both directors. (And for me too, as I recall).
  • The Inexpensive Magnesium Coffin, where a leader's aesthetic desire to have a feature - like Steve Job's desire for a magnesium case on the NeXT machines - led them to ignore feedback from engineers that the case would be much more expensive. Steve overrode his engineers ... and made the NeXT more expensive, just like they said it would, because wanting the case didn't make it cheaper. That extra cost led to the product's demise - that's why I call it a coffin. Elon Musk's insistence on using cameras rather than lidar on his self-driving cars is another Magnesium Coffin - an instance of ego and aesthetics overcoming engineering and common sense, which has already led to real deaths. I work in this precise area - teaching robots to navigate with lidar and vision - and vision-only navigation is just not going to work in the near term. (Deploy lidar and vision, and you can drop lidar within the decade with the ground-truth data you gather; try going vision alone, and you're adding another decade).
  • Egotistical Idiot's Relay Race (AKA Lord Thomson's Suicide by Airship). Finally, the biggest reason for failure is the egotistical idiot's relay race. I wanted to come up with some nice, catchy parable name to describe why the Challenger astronauts died, or why the USS Macon crashed, but the best example is a slightly older one, the R101 disaster, which is notable because the man who started the R101 airship program - Lord Thomson - also rushed the program so he could make a PR trip to India, with the consequence that the airship was certified for flight without completing its endurance and speed trials. As a result, on that trip to India - its first long distance flight - the R101 crashed, killing 48 of the 54 passengers - Lord Thomson included. Just to be crystal clear here, it's Richard Branson who moved up his schedule to beat Jeff Bezos' announced flight, so it's Sir Richard Branson who is most likely up for a Lord Thomson's Suicide Award.

I don't know if Richard Branson is going to die on his planned spaceflight tomorrow, and I don't know that Jeff Bezos is going to die on his planned flight on the 20th. I do know that both are in an Egotistical Idiot's Relay Race for even trying, and the fact that they're willing to go up themselves, rather than sending test pilots, safety engineers or paying customers, makes the problem worse, as they're vulnerable to the Paradox of the Director's Foot; and with all due respect to my entire dot-com tech-bro industry, I'd be willing to bet the way they're trying to go to space is an oversized Inexpensive Magnesium Coffin.

-the Centaur

P.S. On the other hand, when Space X opens for consumer flights, I'll happily step into one, as Musk and his team seem to be doing everything more or less right there, as opposed to Branson and Bezos.
