paper.js VS p5.js

I started with angular and paper.js: http://paperjs.org/

In a thread in the Processing forum, Boolean operations in polygons , user ErraticGenerator suggests using g.js or Paper.js.

It is likely that paper.js provides the functionality needed. I will probably investigate it at some point since it appears to be the more popular library Compare paper.js & bezier.js.

To solve that issue, I searched for some solutions using canvas. I didn’t want to work with pure canvas so after doing some research, I settled with paper.js.

Ooh, the Chebyshev basis is neat. I hadn't seen exactly that before. It reminds me a lot of the "shape control" technique[1] which is also similar to a basis function approach but has a bit of linear solving. Essentially, you get one point (usually at t = 0.5), and also the direction but not magnitudes of the tangents at the endpoints (G1, not C1). This is one of the better-performing existing techniques for offset curve, though does have stability problems (in particular, nasty behavior for a symmetric "S" curve).

Regarding collaboration with Freya, if she is open to it, please get in touch. I do have some ideas.

Paper.js - example (not interactive, just code)

Just remember you can do some SVG displacement with Paper.JS

> <p>Oh yeah, you reminded me of the template fatigue that was paper.js and it trying to reinvent scripting on the client side with <script type="text/paperscript"> templates that could use templates that could use templates... and so on. [0] I was wondering why people would go to such great lengths just to avoid having to script in the browser.<p>The way I saw it at the time was that I've rediscovered the same mistakes that PHP did back in the days. All the recurs(iv)ed templating problems, all the OOP fatigue that never worked out (magento and zend, anyone?), and all the inheritance based "reinventions" of existing web technologies like OOCSS [1].<p>I mean, at some point every engineer should be wise enough to give up on trying to predict the future. Especially in projects they cannot predict what features are going to be implemented, so I'd naturally assume that modularity and compositional or entity/component aspects will win in later revisions or refactor decisions. But I was wrong with that assumption, I guess :S<p>I also can kinda understand the general bias towards closure among functional folks. I guess that lots of people at the time (or nowadays) had high hopes for it allowing to go more "functional" in its approach, allowing compositional patterns to be useful on the web. But, honestly, JS itself is so flexible and can be used in all kinds of architectural patterns that I think closure's purpose is kind of void by its own concept.<p>When comparing closure with, say, typescript (which I also don't agree with, because "string" and "String" and "any" are pointless from any language design perspective): Typescript at least has the benefit of typed API docs and good IDE integrations (due to LSP) that can be used in large teams to reduce the overhead of getting started with working on foreignly-owned code - whereas closure doesn't have any unique selling point in my opinion. I mean, even scala.js has a unique selling point when being judged like that.<p>[0] <a href="https://github.com/paperjs/paper.js" rel="nofollow">https://github.com/paperjs/paper.js</a><p>[1] <a href="http://oocss.org/" rel="nofollow">http://oocss.org/</a>

Our webapp is written with React and Redux using the official react-redux bindings. Another primary library used in this web app is PaperJS. We recently transitioned this to being a Redux app, though it has used React for a while.

I am currently using http://paperjs.org to create an HTML5 canvas drawing app. I want to let users upload images into the canvas. I know I need to make a login and signup but is there an easier way? I have seen the HTML5 drag and drop upload.

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!

Posted an issue for it that u guys can check out here: https://github.com/processing/p5.js/issues/6166
