How did you deal with the gray pixels in the video?

This is very interseting. I came across this on "The Useless Web" and it facinated the heck out of me. They linked this video on the website so here I am. Great video by the way!

Very informs video. Well detailed. Thanks

i was literally just thinking about this

Definitely frustrating.

Where is the repair part? You sent it away and you call it "repair" when you only remount the hands...?

its so weird when i try to pause it and try to imagine the moving animation in noise just to be super off when i unpause it. its like when i try to close my eyes and try to imagine where certain things are and what the general image looks like before i open my eyes again

You said glass. Then acrylic.

I like it. I'd suggest a clamp to hold down the towers. Seems like a tight gap between the bed and the platform beneath it, but it should be doable from the sides without the towers. The bed and printing surface look flexible, which could cause issues too. I don't think that tape is going to work even short term for the pillars.

Neuroscientist here. This is called second order motion and many insects can see this kind of second order motion.

The print quality that you show is not actually that good and your machine can do noticeably better if you adjust wheels on Z. Also, it would be a good idea to level your bed lower (to have all four springs tighter). Also - did you check the flatness of your bed cold, or at printing temperature? There should be quite a difference.

Bro why did you buy an S1 Plus in 2024? Even the $200 V3 SE prints over twice as fast and doesn't make you manually adjust the bed.

I feel like you are conflating good value to a good printer. While the ender will work, it's far from the best. Bed slingers are old news now. Mechanic swith type bed probes are dinotech these days. Youll want a beacon soon enough. You say your not interested in speed. That sounds like something someone that's never waited 3hrs for that last 3% to print would say. Speed is king now. Get those prints printed. Heating that bed isn't free after all. Lots to learn, lots to mod. Hope you have fun.

4:25 Come on, Ender 3 is not as bad as something like Anet A8 (which I had for 1.5 years and the mainboard seems to be damaged now, so I'm planning to upgrade to KP3S) Comparing to an Ender 3 which even has auto bed leveling, Anet A8 seems like a massive pain to work with

Welcome to the 3D printing community!

Having the ability to spot camouflaged predators and prey from movement is a valuable capability as a species.

I believe the white works so well because you're XORing the colours. When you XOR a color with white using binary RGB values, you get the exact opposite of that color, creating a big contrast. The more contrast there is the better you can see it. Edit: This may be why green is good too. The human eye is most sensitive to green color, so when it changes to the exact opposite value you see a lot of contrast. To test this, you can try using colors that have the green value of 128 or 127 where there should be almost no green contrast.

Could you please add a red dot in the middle? I'd like to try if you can see the cube, when having something to focus on to follow the screen shake properly.

I was wondering if the effect is still there if the object isn't moving. That is if you keep the cube stationary but still update the pixles with the same rate along the lines. This should of course be done on a background that is already noise, or the cube will just flash on and off.

Since you are looking for a name for this effect, this might help you finding something: I described this effect to my friends as 'motion without body'

With the word bouncing around on the screen, if I close one of my eyes I can make the text out better. What I think is happening is that with both eyes, the pixels significantly messes with depth perception for tightly packed images such as words.

amazing

this would make a sweet xscreensaver screensaver

suzanne

Really curious to know how this would look paired with motion extraction: ua-cam.com/video/NSS6yAMZF78/v-deo.htmlsi=Hv2kC5-q54HkH_GC

When paused on pc use the: < > keys to really show off the effect

I think an issue with the more complex shapes is that IRL they don't have any "lines". (As in, actual objects aren't made of polygons.) Think of an actual sphere, by it's definition it doesn't have any edges, but this effect relies on them so you end up with a weird dice with many faces (that in this case is easy to see as an imperfect sphere, but with other objects is not so simple to do - like with suzanne). You could try to approximate the shape more closely to show the round edges, but it'd eventually be too jumbled to tell the individual lines apart. All this to say- I think that that's a limitation of the effect, objects have to have enough hard edges to make sense of.

I think that flip book can't work because it is shaking overall. Nothing against your book flipping, it just requires much more stable image. Each pixel need to stay in same place between pages. Even watching computer animations, they get blurry if you shake your head fast enough. I think we can compensate a little for shaking. But if you want to give flip book a second try, maybe try to add a solid frame around the picture, so we have a reference points so we can compensate better? I think in fullscreen, without reference I loose ability to see easier, with smaller, slower head shakes.

On phone, if I try to track the circle with my eyes I see the corners a bit, if I don:t it's completely gone.

1. The blurred version is actually clearer. 2. What happens if you do the operation on the pixels which are empty instead?

I think it would aid visualization if only "important" lines were visualized. That is, for standard polyhedra like cubes, tetrahedra, icosahedra, etc. all of their edges are visualized. For Suzanne, only the outline of its head, mouth, and eyes are visualized. For the teapot, only the outline of its shape, spout, or handle are visualized. Front-facing vs. back-facing lines may be handled separately. I can already kind of picture the algorithm in my mind: 1. Render all faces in white in an off-screen buffer filled with black 2. Edge detection (Edges in white, all other pixels are black) 3. XOR the off-screen buffer with the normal frame It may be possible to render the face normals and run an edge detection on them to generate additional pixels to render.

This is the sort of Jiggle Physics i like

what would happen if the noise pixels are wayyyy smaller

Are you sure that implementation of oklab conversion to rgb is correct in your demo? Clipping might occur at the extreme a/b values, and you look at colors that couldn't be represented as rgb ,nearest will be used, and actual luminance of the pixels will be different. It would be great if there is some check that lab->rgb produced valid sRGB results, otherwise it doesn't actually shows that blues less noticable than reds, because colors got clipped.

You could try only the outline of meshes only, something like what blender does with it's freestyle drawing for edge outlines

I love how the blurred frame just looks like noise when you pause it. I'm wondering what it would look like if the background moved instead of the object. You create a random pattern in the left side of the frame and just continually shift the columns to the right. Or instead of a 'random ' pattern, you wrap the far right column to the left side.

The OKLab luminace doesn't seem to quite correspond to perceived brightness for me - with constant "luminance", blue > red > green > grey. The theory of "brighter perceived colour = easier to see" does still seem to hold though. And subjectively it makes sense, trying to make it out in the grey feels like the same kind of difficult as seeing in the dark.

so many mouth noises ._.

A thing I've noticed: When moving my mouse cursor around the video in a smooth circular motion, my eyes can track the cursor steadily. With increasing speed of the motion, the cube becomes less and less visible. This might be related to the flip-book motion you've mentioned. Maybe one can put either put a white dot on the screen that moves smoothly with variable speed, or the image could be moving by itself, and a fixed crosshair in the middle of the screen could be used to anchor the view.

To easily compare how strong the effect is with different colors, it might be good to update the image monochromatically and color each frame with the selected color as it's displayed.

Is there any chance you missed a conversion from a linear color space to sRGB which causes the dark gray and the green to look darker than the blue and the red at the same L value? Btw, OKLCH is to OKLab what HSL is to RGB.

What about bluring the wire-frame?

what if you make the resolution a lot higher?

i think the best way to make more complex shapes more visible is to isntead of rendering the wireframe, to render hard edges those would include the outline/silhouette of said mesh as well as lines separating any areas where there is a change of depth. sorry, im not good at explaining, but basically imagine looking at a donut from the side, not quite 90° but slightly from top so you can see part of the hole. in that example you would atleast in real life make out the dip because there is a visible edge around the bottom part of the hole. this effect can be achieved by just drawing lines where there is a great change in distance. should be fairly easy to implement by just storing each face's distance from the camera and drawing edges when a certain threshold of change occurs also another thing, about the OKLab implementation and the irregular color intersection chart. the reason some colors just suddenly get bright is because the XOR operation is still happening with RGB. it would be cool to see if there was a way to swap the XOR operation to use the OKLAB L A B values instead

Love this series! There's a popular horror game series called Faith that has a pixel art style, and it has some Very Scary cutscenes with a rotoscoped pixel art style. I wonder how some of those scenes might look with this effect.
