Just posted some #ProcessingOrg folklore (from 2003) to this GitHub issue: "noise() is not Perlin noise"

Github issue comment by me, quote:

"Just to give a little more historic perspective here:

I ported that Farbrausch code for processing.core back in summer 2003. Back then there:

1. wasn't really that much easy-to-find literature or readily available sample code, though two of the most cited & helpful refs was this amazing Hugo Elias article and the noise treatment by the god father of computer graphics.
2. Computers were much slower (and Java too), so for something like noise() to be generally useful (esp. the 2D and 3D versions), we wanted (needed!) to choose a performant implementation and so ended up with the Farbrausch version, which provided the best compromise (also was much faster than other impls I tried & ported back then)...
3. I think it's fair to say that neither Ben, Casey nor I back then considered any of the finer nuances/differences between noise types too much (or at all 😉 )... I proposed a noise() function because I thought it'd be super useful for a lot of different applications and I'd already used it for some terrain & texture generation tasks in a few games I'd developed in Shockwave3D/Director and got some very interesting results from it...
4. I'd have never thought it would stay around (largely unchanged) for that long...

Sorry for any inconvenience caused, heh! :)"

This weekend I wanted to do some fun programming so I played around with Perlin noise. It's a function for generating an even distribution of noise over a coordinate system.

So I wrote a quick app that constructs a bitmap designed to visualize the 3 separate noise functions on a 2D plane.

At a foundational level, this is how Minecraft and other games with procedural generation create terrain variation and generate biomes.

#programming #software #perlinnoise #minecraft #gaming #worldgen

A visualization of 3 Perlin noise functions colored blue, yellow and pink. The blue and yellow are smaller dots wherein the blue is always contained inside the yellow. The pink is spread throughout in larger swaths. Three sliders are labeled; emptiness, energy, and intrigue. Their values are set low in the range.

#genuary27 - Code for one hour

I spent an hour playing with Perlin Noise. Each color is based on the same noise field but with higher octaves added.

#genuary #perlinnoise #perlin #generativeart

Lightning-like lines swirl through the image. Orange lines in the back have more gradual, wide curves. Pinkish lines overlap the orange with nearly similar shape, but a more twists and bends. Green lines on top follow the same pattern with even higher curvature and detail.

#genuary21 - "Use a library that you haven't used before".

Believe it or not, I've never used the Processing library, so I tried it out and generated this image of flow through a Perlin noise field. It does seem nice, but I probably won't adopt it regularly simply because I've already built up my own library of similar graphics functions over the years, and that's what I'm used to using now. I guess I like doing things the hard way.

#genuary #processing #perlinnoise #vectorfield

Lightning-like lines, mostly yellow-orange but with some red sprinkled in, propagate right-to-left across a black background.

So, if your #Python team needs some #TeamBuilding "creative" activities, and your firm has a budget for that, you can call me to teach some terrible coding stuff, like how to create plant-like self-similar shapes with #LSystem (https://en.wikipedia.org/wiki/L-system). Or maybe some #PerlinNoise textures? There is no better way of spending corporate money than contracting me to show dubious graphics code that is almost impossible to test! Don't waste this opportunity!

Im on the hunt for procedural noise that I can give an x and y and it gives me a value between 0 and 1 that would be good for rivers. Please drop some names of algorithms

This is our fun paper on rotating or flow noise. It's a hugely updated follow on from a paper we did in 2014. The demos came out spectacularly!

Is it possible to have #PerlinNoise generate a pattern that will seamlessly loop?

I.E. if I generate a square I want to be able to tile it and have it match seamlessly

#OpenSimplexNoiseInC is a #publicdomain #Simplex noise implementation in #C.

#OpenSimplex noise is an n-dimensional noise generation algorithm that creates noise that follows a natural gradient according to several parameters. OpenSimplex noise is not patented, and has a very simple API with good performance and coherent results without artifacts.
