Matrix digital rain, or Matrix code, is the computer code featured in the Matrix series. The falling green code is a way of representing the activity of the simulated reality environment of the Matrix on screen by kinetic typography. All four Matrix movies, as well as the spin-off The Animatrix episodes, open with the code. It is a characteristic mark of the franchise, similar to the opening crawl featured in the Star Wars franchise.
In the film, the code that comprises the Matrix itself is frequently represented as downward-flowing green characters. This code uses a custom typeface designed by Simon Whiteley,[1] which includes mirror images of half-width kana characters and Western Latin letters and numerals.[2] In a 2017 interview at CNET, he attributed the design to his wife, who comes from Japan, and added, "I like to tell everybody that The Matrix's code is made out of Japanese sushi recipes".[3]
The effect resembles that of older generation green screen displays of monochrome phosphorescent computer monitors.[4] One predecessor of the digital rain exists in a "code-scene" of the movie Meteo, a Hungarian experimental-pop culture movie from 1990. The 1995 cyberpunk film Ghost in the Shell, a strong influence on The Matrix,[5][6] features opening credits similar to the digital rain.
No official version of the code's typeface actually used in the Matrix trilogy and in the website for the game Path of Neo has been released. Several imitations have been made, mostly in the form of screensavers.
Matrix Master Pro is a free Matrix code rain/digital rain animation generator created with HTML5, CSS3 and JavaScript. It is designed as a independent research and art project with the purpose to explore the possibilities of modern web technologies.
The reason why you weren't seeing all characters on screen at once was because you were creating one character at a time, moving it all the way down, and then creating the next character. Instead, you need to initialise all your characters first, then move then down together. I have adjusted your code to:
Inspired by the excellent work done by Sean Foreman here, I spent a couple of hours putting together a simple Unity demo of being in a black void with droplets of matrix-style code 'raining' down around you.
This was an interesting little project to work on. I couldn't just use the Unity particle system because I needed the individual characters of each 'stream' of code to hang in place even as the code descends so had to write a custom system for spawning, moving and orienting each stream as well as giving them appropriately coloured materials. Simple stuff but fun to think about and solve.
Currently no transparency on code materials Not enough streams spawned for a proper Matrix effect Characters not correct Matrix characters Characters hard to read at a distance (I'd be interested to see this on Crystal Cove) Occasional frame rate drops
Matrix code, also known as Matrix digital rain or sometimes green rain, is the computer code related to the Matrix franchise. The falling green code is a way of representing the activity of the virtual reality environment of the Matrix on screen. All four Matrix movies, as well as the spin-off Animatrix episodes, open with the code. It is considered a characteristic mark of the franchise, more or less like the opening crawl is for Star Wars.
In the films, a few people can understand what happens inside the Matrix by looking at the code on computer monitors. Operators from Zion, unable to enter into the Matrix, concentrate on ways to read the scrolling code, or "rain", and infer data from it such as the location of a person in The City, possible exits, and so forth. As the character Cypher explains in the first film, although they have translation software that allows a visual representation of the Construct, the programming of the Matrix contains too much information to analyse in this way, and must be viewed encoded.
The complex "Matrix code" of raining green characters and pictograms allows the Matrix program to be concisely represented and thus read more easily. The character Neo is the only human that can see the code of which avatars are composed while in the Matrix, and is therefore able to see their "true" digital form. By contrast, some programs are not seen as part of the green code, but as golden code (e.g., Seraph).
The code is characterized by green flashing reversed Roman and Japanese katakana characters and Arabic numerals, as well as pictorial symbols, such as a bull's head (as pictured at the end of the Matrix Revolutions title sequence), falling in a black screen while changing and fading. The effect resembles that of the older green screen displays, since the letters leave a fluorescent trace on the screen.
In The Matrix: Path of Neo game the player can press up on the d-pad (on the PlayStation 2 and Xbox version) and the "C" key on the PC Version, and the world would turn into this "code vision." A similar effect is seen when the game is paused. In the Matrix MMORPG, The Matrix Online, the world first loads with everything as green code, slowly fading into a more realistic view.
Though uncredited in the films, Simon Whiteley created the Matrix code. In an interview with CNet, he said that he scanned the characters from his wife's Japanese cookbooks, saying "I like to tell everybody that The Matrix's code is made out of Japanese sushi recipes".[2]
Code similar to that in The Matrix can be seen in an earlier movie Alien (1979, directed by Ridley Scott). There is a scene where Captain Dallas is "talking" with Mother and the "Matrix code" can be seen (even the word 'matrix' is written in the Mother Program main menu screen). Another similarity is where Lt. Ripley (Sigourney Weaver) is seen looking at a monitor with a "green (matrix) code" and she is interpreting the code and understands that the transmission was no S.O.S. but a warning.
In the 1996 movie Independence Day, a code scrolling effect very similar to that of the Matrix code can be seen on the cockpit monitors of the alien flying saucer that was captured by the U.S. government.
There's blessed and node-ncurses which would have helped but rather than using the library I wanted to learn how console cursor manipulation works behind the scenes. I browsed through the source code of colors.js and got a few pointers. On that day I discovered terminal escape codes VT100 ANSI codes table. There is also the comprehensive xterm control sequences documentation ctlseqs.
Node's process.stdout has a columns and rows property. It also fires resize events like the browser. With escape codes I can treat the terminal as a canvas and paint on it. I discovered a new medium to show my art.
Ever wanted that matrix code-rain effect? And procedurally? AND FREE? Well here you go! This implementation lets you control a bunch of parameters (like speed, number of symbols, rate of transition, quantity of transition). I decided not to make this a node group so that you can play with nodes other than the parameters as well easily!
There you have it: mystery solved. The digital rain equates to some delicious sushi. With his blueprint secured, Whiteley adapted written recipes into a computerized visual effect. In the late 1990s, such an imaginative feat demanded meticulous work. However, to retain some of the mystery, he refuses to share which recipe book he used. "It's a magazine, but it's called a book," he hints. "It's something most Japanese people would've heard of or have on their bookshelf."
Justen Marshall, a fellow Animal Logic employee, is the programmer behind the falling "rain" effect, which he and Whiteley switched to once they realized that the text animation moving from left to right per Western reading tradition didn't match the style the Wachowskis were aiming for. Whiteley and Marshall wanted the opening credits to feel more alive and reminiscent of a manga's lettering structure.
The pair adjusted the text's flow to match how Japanese characters are typically read and designed: "back to front" and "top to bottom." Whiteley shares, "When we made it run vertically, and then we let it run, instantly you stopped to look at it. Then once we started building it in space dimensionally, then it looked like rain and rain, of course, has that feeling of sadness and a melancholic feel."
With the main look in place, Animal Logic dived into even more meticulous details. They mimicked "the look of text on an old IBM CRT monitor" to achieve that distinctive green shade. To heighten the sense that something was perplexing, even wrong, they added Arabic numerals to the existing characters (aka the existing sushi recipes) and repeated certain characters. When it came time to overlay the code over live-action images, they "rendered on essentially a flat plane that was directly in front of a camera."
The detailed efforts of Whiteley, Marshall, and Animal Logic paid off. The digital rain remains instantly synonymous with The Matrix to this day. By experimenting creatively, the pair crafted cinema iconography. Since The Matrix, Whiteley has contributed to and collaborated on other projects in different roles. He worked as the concept artist and primary designer for The Lego Movie, was the production designer on The Lego Ninjago Movie and Zack Snyder's Legend of the Guardians: The Owls of Ga'Hoole, designed the opening title sequence for George Miller's Babe, and served as the visual effects designer for Terrence Malick's The Thin Red Line. Marshall was the R&D Supervisor on Legend of the Guardians, The Great Gatsby, and Happy Feet, and the software development manager on the sci-fi film Knowing.
