cannon-es VS mathjs

// ============ // part 2 // add base vehicle body // reference: https://github.com/pmndrs/cannon-es/blob/master/examples/rigid_vehicle.html // ============ const carBody = new CANNON.Body({ mass: 20, position: new CANNON.Vec3(0, 6, 0), shape: new CANNON.Box(new CANNON.Vec3(4, 0.5, 2)), });

cannon.js hasn't been maintained for 7-8 years, the project lives on here https://github.com/pmndrs/cannon-es you import it like so

Cannon-ES - 3D physics engine

Since I'm a big Poimandres fan I looked into react-xr, and it was very easy to get a first WebXR project up and running. Unfortunately, there are many dependencies in the ecosystem which slowed me down: react-xr is built on top of react-three-fiber which is built on top of Three.js, and physics is enabled by use-cannon which is built on top of cannon-es. For a long time I was running into issues and helping fix them with a couple of pull requests, and ultimately it was preventing me from working on the actual project. Still, Poimandres is a great community and I got a lot of inspiration from the content being shared in the discord.

This was the post I was remembering, see repo here: https://github.com/pmndrs/cannon-es

btw canon has been abandoned for years. it continues to receive support on here: https://github.com/pmndrs/cannon-es which next to bug fixes also gives it types and esm/tree-shaking.

The Math blocks are powered by Math.js (https://mathjs.org/).

math.js is a comprehensive JavaScript library that offers support for working with matrices and multidimensional arrays. It contains a huge array of mathematical functions in addition to array operations, making it suitable for a wide range of mathematical activities.

ii) Third-Party Libraries There are various libraries like math.js, decimal.js, big.js that solve the problem. Each library functions according to its documentation. This approach is comparatively better.

mathjs integration. Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices. Is compatible with JavaScript’s built-in Math library. Contains a flexible expression parser. Does symbolic computation. Comes with a large set of built-in functions and constants.

hey, this looks interesting. there is library, mathjs , that is providing pretty printing , which I'm looking for.

It's because it's not supported out of the box by the mathjs library I'm using: https://mathjs.org/

I agree that this would be nice.

Ha, yes, I was being nosy. It was quite easy to spot as it's the only XHR/Fetch request.

I was intrigued what you had used to build it, and if you had built your own solver (which you have), and what editor you used (Code Mirror) so went looking at the code. Interesting to see you left the source maps for production, made it easy for my sleuthing...

I experimented with a similar idea last year, but used ProseMirror/TipTap as the editor to enable rich text editing, and the MathJS (https://mathjs.org) solver. I also combined it with PouchDB and Yjs for offline editing and syncing between devices. Never finished it though, you have kept your nice and simple!

This is nice but I believe something much better can be achieved using JavaScript, in particular math.js.

I also found this math input library: http://mathquill.com/ , and https://mathjs.org/ seems to contain code for solving math problems.

What about math.js? It has an expression parser that looks pretty nice.
