#CMYK color model is weird...

Continuation of fixing starter deck art! Again, players should have a good first impression to lead them into the rest of the good impressions :3

Wargreymon - So boring before! But now he’s dynamic, about to charge up that Gaia Force. I did a lot of shading fixes to this one after my wife posed it. I tried to get as much depth from darks to lights as possible everywhere, without putting in the same insane work I did for the Dracomon.

Guilmon - Before, it was absolutely comical. Low-res t-pose lol. But the shiny new Guilmon is cool and cute. This was a tough pose because we wanted a more feral Guilmon but the model is rigged to be...weird? It’s hard to describe the way Toei-style models are rigged. They work closer to stubby humans than the demons and animals being depicted.

Coliseum - I’ve waited a long time to fix this one. After finally understanding some things about 3D modeling, I was able to isolate a real example of a Digimon coliseum and use that. I made some texture and color edits so it would stand out even more.

Hyper Disk - Gone are the days of using 2D CG, this is an actual 3D diskette model. The rainbow is now CMYK compatible so prints won’t look as ugly.

The Dancing Men

Before Reading

Warnings: Suicide mention and stalking.

Tangent: If you watch BBC Sherlock, you need to read this story to understand Mary. 

“Now, in my opinion, Dupin was a very inferior fellow. That trick of his breaking in on his friends’ thoughts with an apropos remark after a quarter of an hour’s silence is really very showy and superficial.” - Holmes on Poe’s Dupin, STUD

After Reading

Tangent: A, E, H, I, N, O, R, S, and T are the most common letters in the English language, at least American English. R, S, T, L, N, and E are what you get in the “Wheel of Fortune” bonus round. The dancing men are an example of a simple cipher, not a code (Khan Academy).

Tangent: “At last the violet rim of the German Ocean appeared over the green edge of the Norfolk coast…” That ocean isn’t purple. It also isn’t a wine-dark sea. It’s more likely to be like the indigo you see in a rainbow. 

Humans tend to have three cones to detect color: one for short wavelengths, one for medium wavelengths, and one for long wavelengths. These approximately correspond to blue, green, and red. We call these the three primary colors of light. They are the three primary colors because of the three types of cones. We perceive daylight as white. It has the full spectrum of visible light. Mixing pigments together is subtractive: the more colors you add, the closer to black you get. Mixing light together is additive: the more colors you add, the closer to white you get. That’s how you get printers using a CMYK model (cyan, yellow, magenta, and key tone [black]) while computer screens (such as this one) use blue, green, and red. 

[Keep in mind that I’m writing this in English and my first language is English] 

The way we divide the spectrum of visible light and give those divisions names is dependent on language and culture. I say red and pink and not red and light red. (Blue-Green color distinction in language) I learned ROYGBIV: red, orange, yellow, green, blue, indigo, and violet. Nothing has color; we perceive the wavelengths the thing reflects. Plants are usually green. The chlorophyll absorbs red and blue light and reflects green. Color is how we describe a small piece of the electro-magnetic spectrum. Bees have a different range of the spectrum than we do. (How Bees See and Why it Matters) We can perceive red better than they can, but that doesn’t mean it’s any less or more real than the ultraviolet they can perceive. It’s just a different range. 

I would describe the color pourpre (French) as red-violet and the color uaine (Scots Gaelic) as blue-green. Tyrian purple, the dye from the Mediterranean made from snails, is close in color to pourpre. 

Some colors are very weird. Purple is what you get when you mix red and blue pigments. Red and blue are on opposite ends of the visible light spectrum. Purple is a non-spectral color; it can’t be perceived using a single wavelength. There’s also blue-yellow and red-green which are considered impossible colors. It’s like trying to balance a light switch between ON and OFF. They’re best explained by opponent process theory. It’s also why, when you stare at yellow shape for a long time and you look away to a white wall you see the same shape but in blue. 

Dates: Queen Victoria’s Golden Jubilee was June 6, 1887. One year ago, was the Jubilee and the marriage. This sets DANC in 1888. One month ago, was the end of June. About a week ago, it was Tuesday. Hilton Cubit visits Baker Street.

The next morning, a second message appears. Three days after his visit, a third message. Six days after his visit, a fourth message. That night he stayed up to two in the morning with only moonlight illuminating. This would make you think it’s a full moon but, that night cannot be Monday July 23, 1888 because there was a total lunar eclipse. The next full moon wasn’t until August 7. 

A fortnight or so after Cubit’s first visit, Hilton Cubit returns to Baker Street. Two days later, the final urgent message arrives. Holmes and Watson travel to North Walsham the next morning. Now it is late July or early August 1888, immediately before SIGN.

The gorgeous future of 3D printing

MIT Media Lab’s Mediated Matter group has invented a new way to 3D print any object, regardless of how complex it is, with color and shape as detailed as a photograph. It’s the equivalent of traditional CMYK printing, but in 3D. The results are stunning.

Until now, we couldn’t print certain types of data models in 3D. The interconnected neuronal tissue in the brain or an interstellar dust cloud, for example, have many scattered structures that float in space with no connection to other structures. This poses a problem for 3D printing: A 3D-printed object typically needs to have all its parts connected–so complex objects with weird topologies were impossible to make until the Media Lab came up with this method.

A new paper published in the May 2018 issue of Science Advances, describes the method, and it works like this: Rather than trying to build stand-alone objects, it uses different materials to create a solid transparent block in which the photorealistic object is encapsulated. That way, something like the stars and clouds in a nebula can be printed “floating” in 3D space.

These floating dots that form the 3D object trapped inside the transparent material are called voxels. Voxels are just points in 3D space, little dots that result from the division of an object into a 3D array. Each little dot that forms a volume has assigned three coordinates (X, Y, and Z), which place the dot in a 3D space. The process is similar to traditional 2D color printing. But instead of printing on a piece of paper, you’re printing out layers that get stacked on top of each other. When it’s done, you get a full-color, 3D-printed model encapsulated in a clear block, like a Jurassic bug forever trapped in amber.

The technique allows you to create photorealistic 3D representations of anything you can imagine–imagine the face of someone captured in 3D with a stereo camera and printed this way, with every single hair and pore clearly defined. It also has significant potential in education and scientific visualization: While you can look at a 3D representation of data in virtual or augmented reality, looking at a real physical model is an experience that is hard to beat.
