For My 26th Sketch of Mathober2025 (curated by @fractalkitty ) , MetaLegendre is coded with #SonicPi & #Desmos. For the 11th Prompt of Orthogonal Polynomial, uses a desmos sketch that half of the Legendre Polynomials are in 2D and the other half are in 3D. For the 27th Prompt of Bidiminished, the sound is control by the volume of a Metabidiminished Icosahedron.

I may have let things get a liiiiiiiiiittle out of hand when trying to handle the edge cases of this percentile function in #desmos.

An absurdly long function defined in Desmos online graphing calculator. It takes two inputs: a percentile, and a list. And then it has six different conditions --- all on one line because Desmos is just Like That --- detecting various shenanigans: percentiles outside of (0,100), indices that fall partially outside of the first or last element of the list, and other non-integer indices (and of course the happy path of an integer index within bounds).

Never though noise was so overrated, we really just need a few sin waves...

#desmos #maths

A mini terrain in desmos 3d:

z = 1.5-total([|total(sin(2^i*R([x,y],i*a)+o)*s/2^i)| for i=[0...N]])

R() is a rotation function, N the number of octaves, s a scale, o an offset, a an angle.

Waah #desmos 3D is such an incredible tool...

Looking for a libre alternative to Desmos online graphing calculator? (desmos.com/calculator)

I found grapk.tk!

It used to be on graph.tk, but that address no longer works - yet the name of the project remains.

So it's now here:
graph.equation.io/

github.com/aantthony/graph.tk

#WCCC #wccchallenge #Livecoding #CreativeCoding #3danimation #drive #hyperdrive #scifiart

For this week's Creative Code challenge by @sableRaph: “Drive”, HyperDriveInstallation is created as a representation of what a Hyperdrive could be. Done by using the Primary Ion Drive Object from #ThreeJs within The #Locomotion code & an object made in #Desmos , #HydraVideoSynth and glitch effects to mimic portions of the Hyperdrive and a #SonicPi composition to add an audio layer.

#Poem

Hyper Drive
Beyond the Speed
The Speed of Light
For this is A speed
That is beyond the Reach of Sight
As it impedes
To feel its stride
To feel alive

I had fun making sounds in desmos to go with this:

I don't know who needs to hear that, but if you need to call atan(x) with x in [-1,1], a linear remapping (straight line) to [-π/4,-π/4] is an okayish approx.

I checked the hermite (smoothstep), and it's also kinda acceptable, just the other way around.

Then I thought "their average could be interesting"... And it's indeed actually pretty good!

Is this useful? Probably not.

Simplifying the expressions, you get:
atanlol(x) = mix(-π/4,π/4,(x+1)/4+smoothstep(-1,1,x)/2)

Desmos curves showing that atan, a straight line, a smoothstep, and the average of the 2 latters.
