Programming Flow Fields

- Use flow fields to create beautiful patterns. Program with Java (processing) to create flow fields that can be used to procedurally generate colorful images or simulate the movement of particles through complex fields of forces.
This is a fantastic video. Very interesting concept and lovely demonstration of Processing as well! Please keep up the incredible work, it's wonderful to see content like this.
Thank you! I'm glad you enjoyed it. If there are topics you'd be particularly interested in, please let me know. I'm always looing for new ideas.
This is really cool.
You should try with particles that die after some time and respawn randomly. Maybe moving the flowfield.
Im sure you know this but to map a number N (0,1) to 0, Max. You can simply do N*Max. The beauty of normalized values.
Or 0,1 > a,b = a + n*(b-a) (iirc)
Which is useful on vectors.
I'm glad you enjoyed it. The dying and respawning is clever idea, I'll have to give it a try.
Thanks for the comment about N*Max. I tend to fall into the habit of using the same tools even when they are not ideal. In this case I had been using map() a lot and didn't stop to think about the simpler approach.
Great explanation. I'd seen genart based on flow fields but this really demystified it for me.
Thank you! I'm really glad it was helpful.
an interesting and informative video, i liked your channel.
Thank you! I try to get a new video posted every few weeks. If there's any topics you would like to see please let me know. I'm always looking for fun new projects.
Thanks Terry. You made an other clear explanation of a difficult concept.
I'm glad it was clear. I was worried that some of the discussion about applying forces to the particles wasn't great.
Thanks for posting this! It's really interesting to see. I'll have to see if I can apply it to make some control systems art!
I'm glad you enjoyed it. If you create anything you want to share feel free to post a link in the comments are let me know and I may be able to mention it in a future video.
Just finished implementing a vector field illustrator in C after taking inspiration from your video :)
Love your channel
I'm glad it was helpful. Which graphics library do you use with C?
@@programmingchaos8957 I use the SDL library for linux

Really well put together video and great explanation, thoroughly enjoyed thanks!
Thank you! I'm always on the look out for new topics. If there's anything you think would be interesting or would like to see explained, please let me know.
EnslavedInTheScrolls on Reddit suggested a number of links with even more fun things to try with flow fields:
www.reddit.com/r/generative/comments/mp2020/well_thats_a_twist/ a very colorful image based on careful selection of the flow field
www.reddit.com/r/generative/comments/muib0b/twisted_texture_2k/ and with some added noise
www.reddit.com/r/generative/comments/n7hnsc/57th_flow/ more patterns
www.reddit.com/r/generative/comments/nndv7v/warped_weft/
www.reddit.com/r/generative/comments/s4tckg/genuary2022_martian_sandstone/ using angles to generate the hues
How do you do this? I love math and I want to do projects like this? What programming tools do I need. I have a knowledge of backend programming
Hi! It's all done using Processing, which is really an environment for easy graphical programming using Java. You can download Processing for free here: www.processing.org. It takes about 3 minutes to download and install and is super easy (download, unzip, open the folder, start-up processing.exe). If you're new to Processing some of my other videos are a bit simpler projects and I spend more time on the basics of Processing: ruclips.net/video/T-_OTFEP7rg/видео.html, ruclips.net/video/tWqeWJikOCI/видео.html, and ruclips.net/video/_OgU-F0bpoQ/видео.html are all pretty good for getting started.
@@programmingchaos8957 thank you so much, what other programming language can I write? I'm familiar with PHP, python and JavaScript.
Using Javascript you should be able to create a canvas and do similar drawing operations to it. Or in Python using either the pygame or turtle libraries should allow you to do similar drawing. But I'm not familiar enough with either of them to know how much you would need to modify the code.
And for even more on different types of images that can be generated with flow fields I would recommend Tyler Hobbs' website: tylerxhobbs.com/essays/2020/flow-fields.
