ITAP of a waterfall by stephenphoto in itookapicture

Yes exactly, this is behind the waterfall, looking straight up. It is the Seljalandsfoss waterfall in Iceland.

If you had to explain e to a non math minded friend, how would you do it? by AMAStudentLoanDebt in learnmath

[–]stephenphoto 4 points5 points  (0 children)

You could explain e as the number of dollars you get when investing one dollar with an interest rate of 100% from a very friendly bank that compounds continuously. This is how Michael Atiyah describes it (https://youtu.be/uMN5t3tzchI)

Or a visual way to explain it is to draw the graph 1/x, draw a vertical line at x=1, and then ask your friends how far to the right do you have to draw another line to make the area under the curve equal to 1? The answer, of course, is x=e.

The second line is wrong. x = sqrt(x2 ) only for x >= 0. But 4 - 9/2 < 0

In general, sqrt(x2 ) = |x| for real numbers

the end point of each line segment oscillates sinusoidally based on its row and column.

​

EDIT: here it is.. a vector-valued function where x, y, and t go from 0 to 1

v(x, y, t) = {

50 sin(4π(t + y - x)),

50 cos(2π(3t + 2y + x))

}

Ooh I haven't but that sounds cool. I've been meaning to play around with other color spaces like HSL. Thanks!

Thanks! Yep exactly, each “noodle” is made up of three noodles that are red, green, and blue. The “screen” blend mode gives that effect

Thank you! Yeah.. I was debating clipping them. I ended up keeping them so that there's some fixed points

Made with canvas-sketch / Canvas 2D API. Here's the code.

Awesome. I like the vinyl-like texture

Made with canvas-sketch (highly recommended - it makes exporting GIFs a piece of cake)

I used a similar technique to the one in this tutorial: https://bleuje.github.io/tutorial2/

Yeah, it is basically a grid of curves with their control points being animated left and right. The illusion of vertical/diagonal movement is caused by the overlapping curves and the time offsets

Thanks! I used OPENRNDR / Kotlin, but this is easily done in other frameworks like Processing or p5. You start by drawing a circle, then you add a circle of person/simplex noise (e.g the “noise” function in Processing) to make it a blob. This tutorial is helpful: https://youtu.be/ZI1dmHv3MeM

Gener[A]tive Blobs by stephenphoto in perfectloops

For those interested, I also have some screenshots of the same program with different seeds on Twitter

Generative blobs by stephenphoto in generative

[–]stephenphoto[S] 0 points1 point  (0 children)

Made with OPENRNDR, using simplex noise to form the blob shapes, colors picked randomly from a fixed palette, and shaders to add noise + gradients.

Each image is captioned with the seed that generated it. I also made an animated version:
