ccapture.js VS p5.js

I also tried to find a better recording method. Since I’m now using canvas, there are some solutions to recording that seemed quite elegant. For example, paper.js uses requestAnimationFrame to achieve its smooth animation. There are libraries like ccapture.js that hooks into the various methods like requestAnimationFrame and setInterval, allowing it to render each frame separately.

I actually spent a fair bit of time on this and eventually got something to work. Someone named "spite" made a great library called CCapture for doing this, but it needs to be updated and repackaged for ES6. Right now it is painful to integrate into your project, but it could be super-easy. You can help to encourage someone to fix the issues here.

Check out CCapture.

The image capture step uses ccapture to ensure that the playback frame is converted to an image. All frame images to webm video.

ccapture.js basically let's you write out frames from a threejs camera, which you then stitch together with ffmpeg.

I use ccapture, using the png option, which will spit out a tar with a png of each frame, and then I stitch them with ffmpeg.

This video is 1800 frames (30 FPS * 60s)... a browser trying to save 1800 individual frames would lock up and die. Ccapture.js hooks into the browser's rendering code and captures the frames as a 'blob' - a binary object that is often used for streaming video - and then wraps them up into one single download.

p5.js runs the sketch, ccapture.js captures all of the frames (1800 in this video), and ffmpeg combines the frames into an MP4.

I use ccapture.js, which captures the frames as a blob in real-time then exports it as a .tar file full of jpgs when the sketch is finished (with 'finished' defined as reaching 1800 frames, in this case). This is a lot better than having the browser try to save 1800 jpgs the usual way.

Processing (P5) had this: you can select any string of text in its IDE anl search for it in the docs, and if it's one of the built-in functions or constants it will open the associated static html page that came installed with the software, so no internet nor server required. And despite being offline you can still navigate the docs too. This feels a lost basic skill in static site generation these days.

It was the only creative coding framework that had complete, offline documentation like that at the time I might add. OpenFrameworks is still mostly autogenerated stubs for example.

IMO it was one of the things that gave Processing an edge in educational contexts over all alternatives. I was pretty sad to see p5.js not fully continue that tradition and require that you go online to read the docs, and that it's not a static website but that text is rendered with javascript when you open it (still complete and with examples though).

I thought it could be funny to use the javascript version of it https://p5js.org/ in a web page and then wrap it in a Unity app, since Unity was and is the environment I use for making apps.

In this last section, I'll be creating some visual examples to show how helpful loops can be. I'll be using p5js, a JavaScript library with functionality for creative coding. That being said, I'll try to give a condensed version of the functions being utilized in the following examples.

I was curious too, took a little bit of digging :)

"the original domain of [P]rocessing was proce55ing.net, so people used to sometimes refer to processing as proce55ing or P5 or p5 for short. they still do sometimes. p5.js is a reference to that."

> how do I get him learning programming in a fun way?

Processing / P5.js can be pretty fun to learn. You use a real programming language to create art and animations. With little code you can get a circle on the screen, then making it move, then following your mouse, then adding other shapes, then changing colour depending on some event… It’s conductive to experimentation and a way to gradually introduce concepts.

Then I used p5js to create the 'art' itself, really user friendly coding framework with lots of resources online! If you want to get into coding, that is a really great entry point with Daniel Schiffman's coding train videos on YT!
