RGB K-D Tree (2016)
- LordNibbler 3y agohttps://allrgb.com/radiator https://allrgb.com/radiator does something weird to my display, the lines extend beyond the window
- magicalhippo 3y agoYeah same here. Had it with other "pulse trains" or similar harsh repetitive structures. Guessing it's some resonances in the cable or so?
- sgtnoodle 3y agoI believe it's typically a resonance in a power supply / voltage regulator.
- magicalhippo 3y agoAh yes, that makes a lot more sense.
- TehCorwiz 3y agoYeah, I get weird horizontal lines that follow the image but extend to the edges of the screen. Since it extends to both sides it doesn't feel like a panel artifact, but a processing one.
- jey 3y agoThese are impressive, I wonder how he computes them: https://allrgb.com/al-zimmermann https://allrgb.com/al-zimmermann
- haneefmubarak 3y agoAccording to the user on that site "alzayani": sort an array of all 16777216 image positions (x,y) randomly loop the positions array and for each position: read the pixel color at the position as a reference sample N random colors from the available colors list for each sample calculate the hypotenuse from the reference color Math.hypot(R - r, G - g, B - b). find the nearst color, use it for that position in the output image update the list of avalible colors (for practicality in chunks)
- willvarfar 3y agoWait, is that the Al Zimmermann, who runs the massive recreational math programming contests http://azspcs.com/ http://azspcs.com/? Without looking into what these images actually are and how they are generated, they remind me of mosaics I've made of hobby game contests https://williame.github.io/media/old/143376853353_1.jpg https://williame.github.io/media/old/143376853353_1.jpg using https://en.wikipedia.org/wiki/Hungarian_algorithm https://en.wikipedia.org/wiki/Hungarian_algorithm, except _better_.
- TehCorwiz 3y agoWow, that's some impressive dithering. No lie, the "grayscale" images are the most impressive to me. Reminds me of color half-tone printing and film grain. I wonder what videos games look like in this visual interpretation. I want this as a shader.

- ChrisArchitect 3y agoFYI: This project site is a gallery of images created using one pixel for every RGB color (all 16,777,216 of them, no duplicates)
- notfish 3y agoOh wow, I make those too using a similar technique: https://tim.fish/assets/images/omni/drip.png https://tim.fish/assets/images/omni/drip.png https://tim.fish/assets/images/omni/splut.png https://tim.fish/assets/images/omni/splut.png The code is here if you’re in the mood to be morbidly fascinated by my hacky python https://github.com/TimEwing/omni https://github.com/TimEwing/omni Worth noting mine are only 7-bit instead of 8-bit because my poor little lenovo kept running out of ram and crashing.
- OnlyMortal 3y agoCan you use a memory mapped file?
- zX41ZdbW 3y agoIt reminds me of a project I've built recently: https://reversedns.space/ https://reversedns.space/ Although it is not guaranteed to contain every RGB color, it is very likely.
- hoseja 3y agoWhy is "random RGB" instantly recognizable by the weirdly large/disproportionately noticeable amount of "random RGB purple" (#C31BEE for example)?
