Can someone here explain how this works?
I'm not sure how reliable it is, but here'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.

#42Fun, there was a program for the Amiga called "Doug's Math Aquarium" which I found to be pretty neat, it has a lot of that feel. Don'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.

#43I can't wait to play Super Mario in this when someone inevitably makes a 3D rendering engine in it.

#44This is my favorite online graphing calculator. It's been around for a while. It got me through pre-calculus.

I use it for (some) quant finance work. It's not a toy, shockingly versatile.

#46Thank you to whomever thought about gimbal lock when designing the rotate controls.

#48This is very cool. I'm involved with an open source project that's similar to this, called 3Demos: https://3demos.ctl.columbia.edu/

Nice! Really good to know. We'll add that to our list of device/browser combos that might cause trouble so that at minimum we can warn folks. It's an early beta so we're enthusiastically collecting any examples (system configurations and also graphs) that cause problems, so if you see anything amiss we'd love to hear about it (feedback@desmos.com). [disclaimer: I work at Desmos]
Since you work at Desmos: is there any way to have animated variables start/stop based on the value of some other variable? Or functions that graph different formulas based on a conditional? Etc. For example, variable X is continuously cycling between -10 and +10, but only when variable D is > 1. At my son's school, there is a kind of interactive demoscene going on using Desmos (the kids believe that the school canno…
Fun question. There are a couple options:
(1) the more straightforward (but less powerful) option is to use the dynamic bounds for a slider. Here, "a" is set to animate, but the bounds don't let it move if b=0: https://www.desmos.com/calculator/mqhhpso67r
(2) the more general feature that allows for complex scripting behavior is called "actions." Here's an example that uses that, where it's more of a genuine play/pause: https://www.desmos.com/calculator/gzqwx36lo0
It's a beta feature that needs to be enabled, but anyone can turn it on. More here: https://help.desmos.com/hc/en-us/articles/4407725009165-Acti...
Re: Desmos 3D graphing calculator
#50Desmos is the best, free (as in cost) and easily accessible graphing calculator out there. I wish it was opensource though. I've even tried to make an alternative and it's really hard to match their functionality (or I'm just inexperienced). I hope an opensource alternative crops up. Edit: Seems there has https://www.geogebra.org/
GeoGebra is the closest I know, at least when limiting to copyleft [or theoretically the SQLite model would be fine, but it's pretty unique in dependability and selflessness for open source projects not subject to copyleft] "middle/high school (constructive?) geometry & function graphing teaching aid" classroom-grade robustness: bored & curious children are somewhat creative in their play/"(ab)use" of teaching/classr…
One of my favourite things about (desktop) Geogebra is its ability to export to tikz. Making complicated geometric shapes in a latex file can be done so easily with Geogebra. Perhaps not as elegant as Castel, but still quite nice.
