Desmos 3D graphing calculator

There are a bunch of YouTubers making Desmos animations. I haven’t played with it myself, but always find it fascinating with what people come up with.<p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;4_8eY_Ij-5k" rel="nofollow noreferrer">https:&#x2F;&#x2F;youtu.be&#x2F;4_8eY_Ij-5k</a>

Well it passes the sin(x)sin(y)sin(z)&gt;0.1 test<p>Edit: also sin(x)sin(y)sin(z)+0.1sin(10x)sin(10y)sin(10z)&gt;0.1<p><a href="https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;85d41ad6c6" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;85d41ad6c6</a>

Thank you to whomever thought about gimbal lock when designing the rotate controls.

Woah - <a href="https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;9eb92bb6e2" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;9eb92bb6e2</a> - an implicit surface!

This looks nice, and I could see using it in some cases when I teach 3D functions, especially for complex functions that require more accuracy. But when introducing 3D it&#x27;s often nicer to have graphs that showing gridding rather than smooth curves. For most purposes I&#x27;ll probably stick to CalcPlot3D. It also has some nice features for showing points and vectors on a function, doing contour plots, and a nice surface of revolution visualization.<p><a href="https:&#x2F;&#x2F;c3d.libretexts.org&#x2F;CalcPlot3D&#x2F;index.html" rel="nofollow noreferrer">https:&#x2F;&#x2F;c3d.libretexts.org&#x2F;CalcPlot3D&#x2F;index.html</a>

Our math lab teacher in high school made us create a 2d functions representation on an infinite cartesian chart, with integrals and derivatives. Then I extended the program to print 3D functions with rotations and rainbow colours.<p>Was a great project in C#, since it all started with a dot on a canvas, and all the rest of things was composed extending the base objects.<p>(x^{2}+9&#x2F;4y^{2}+z^{2}-1)^{3}-x^{2}z^{3}-9&#x2F;(80)y^{2}z^{3}=0

Desmos is the best, free (as in cost) and easily accessible graphing calculator out there. I wish it was opensource though. I&#x27;ve even tried to make an alternative and it&#x27;s really hard to match their functionality (or I&#x27;m just inexperienced). I hope an opensource alternative crops up.<p>Edit: Seems there has <a href="https:&#x2F;&#x2F;www.geogebra.org&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.geogebra.org&#x2F;</a>

Can someone here explain how this works?<p>I&#x27;m not sure how reliable it is, but here&#x27;s[1] an old Reddit comment describing the method that Desmos (2D) uses. That method works in 3D, so maybe Desmos 3D uses it, too.<p>[1]: <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;desmos&#x2F;comments&#x2F;qlhmbc" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;desmos&#x2F;comments&#x2F;qlhmbc</a>

I like calc paired with gnuplot.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;lcn2&#x2F;calc">https:&#x2F;&#x2F;github.com&#x2F;lcn2&#x2F;calc</a><p>inb4 dc(1)&#x2F;bc(1)... calc supports complex numbers, C-like pseudo structures&#x2F;functions, custom decimal points and lots more.<p>Also, calc&#x2F;gnuplot will run on a toaster or even legacy systems from 20-25 years ago.

This is fantastic! So easy to move, zoom and rotate the graph with exactly the mouse buttons you&#x27;d expect. In most even commercial math packages this is always super clunky

The equation editor is so intuitive. Here&#x27;s something I got from just typing in stuff and tweaking it: <a href="https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;6f4cd9930d" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.desmos.com&#x2F;3d&#x2F;6f4cd9930d</a>

That&#x27;s awesome, just rotating the cube is fun.<p>Makes me think of space maps for some reason in scifi<p>Edit: I know there&#x27;s cool stuff to graph like saddle from calc 3

Fun, there was a program for the Amiga called &quot;Doug&#x27;s Math Aquarium&quot; which I found to be pretty neat, it has a lot of that feel. Don&#x27;t know how to get it to insert i (aka sqrt(-1)) but that can be worked around. Another fun thing would be color gradient for magnitude. Definitely fun times and super quick.

I can&#x27;t wait to play Super Mario in this when someone inevitably makes a 3D rendering engine in it.

Go ahead and spend an afternoon exploring sinusoidal waves: <a href="https:&#x2F;&#x2F;www.desmos.com&#x2F;calculator&#x2F;w9jrdpvsmk" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.desmos.com&#x2F;calculator&#x2F;w9jrdpvsmk</a>

Demos blog post about this: <a href="https:&#x2F;&#x2F;blog.desmos.com&#x2F;articles&#x2F;beta-3d-release&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;blog.desmos.com&#x2F;articles&#x2F;beta-3d-release&#x2F;</a>

Desmos is honestly probably one of the best things to come out of the web- it&#x27;s an impressive tool and I am truly thankful for all the insight it&#x27;s given me in my mathematics classes. Super stoked to see what bananas things the desmos community makes with this!

Can anyone recommend calculator to explain basic concepts to 10 year old? Like 3 * 10 = 30. Or 100 * 200 = 2000. Or 3 * 3 * 3 = 27, etc.

The 2D calculator could already display 3D curves with a projection layer [1], but it&#x27;s nice to have it built-in. I built a few models of analog hardware with that trick that brought it to its knees back in 2016.<p>[1] <a href="https:&#x2F;&#x2F;www.desmos.com&#x2F;calculator&#x2F;atydw7bpnu" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.desmos.com&#x2F;calculator&#x2F;atydw7bpnu</a>

This is very cool. I&#x27;m involved with an open source project that&#x27;s similar to this, called 3Demos: <a href="https:&#x2F;&#x2F;3demos.ctl.columbia.edu&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;3demos.ctl.columbia.edu&#x2F;</a><p>On github at <a href="https:&#x2F;&#x2F;github.com&#x2F;ccnmtl&#x2F;3demos">https:&#x2F;&#x2F;github.com&#x2F;ccnmtl&#x2F;3demos</a>

This is my favorite online graphing calculator. It&#x27;s been around for a while. It got me through pre-calculus.

I try with this example sin(x^2+y^2)<p>Obliviously, this function is centrally symmetric. However, when rotating the graphic, it can be seen that the ripples on the surface are not uniform. I believe this is due to the sampling method. Take a look and see if there are any areas that can be improved.

Desmos has had a place in my bookmark bar for years now this is a very cool addition.

3D saddle formula:<p><pre><code> f(xy)=z </code></pre> Sphere:<p><pre><code> (x-h)^2+(y-k)^2+(z-l)^2=5^2</code></pre>

it&#x27;s a fun thing to do<p>here&#x27;s a &#x27;hyperdimensional&#x27; plotter i built when i was 18?<p><a href="http:&#x2F;&#x2F;skylab.org&#x2F;~felix&#x2F;hyperspace&#x2F;animation.html" rel="nofollow noreferrer">http:&#x2F;&#x2F;skylab.org&#x2F;~felix&#x2F;hyperspace&#x2F;animation.html</a><p>you can surprisingly get very far with a little JS<p>these days I default to plotly for most things, the wolframalpha.com when i&#x27;m really lazy. i do have a friend that has been smitten by mathematica for the past decade though

Thanks desmos, for making my calculus assignments enjoyable.

I&#x27;ve used this thing so much throughout the years and love it. Super helpful when making shaders and stuff to test ideas.

Nice! What is the onscreen keyboard is integrated into the calculator? Is it your custom solution, or some publicly available?

Very cool.<p>Reminds me of dwitter:<p><a href="https:&#x2F;&#x2F;www.dwitter.net&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.dwitter.net&#x2F;</a>

what&#x27;s the relationship between desmos and geogebra? is one a fork of the other one?

I’ve been using their 2d graphing calculator since college and love it

Very great! Is there a way to increase the resolution though?

Is it possible to model anything with a single equation?

didn&#x27;t realise desmos had a desktop client, but i&#x27;ve been a happy user of their android app for years. best calculator on android by far.

Is Desmos open source ?<p>What&#x27;s the pricing for commercial partners?

Curious if this is using WebGPU

Super cool!

Wow this is painfully slow, the CPU usage for rotating the scene is insane, I can&#x27;t look at the code right now but wow.. I expect better from them<p>EDIT: If you are using Chrome, make sure you are on the latest version, the latest v118 fixed it for me
