Tim Reinhardt, a person in a gray sweater, leans over their laptop at a desk in a lecture hall. The projection screen behind them shows a code editor with JavaScript and a colorful, star-shaped phase portrait visualization.

Tim Reinhardt stands in a lecture hall, holding a microphone and looking up at a projected slide. The slide shows a detailed code editor and a vibrant, complex mathematical visualization with rainbow-colored patterns.

Steve Trettel, a person in a blue t-shirt and baseball cap, stands in front of a projection screen with their hands raised. The screen shows a digital interface with a glowing, blue-and-orange organic-shaped visualization. Boxes of chalk are lined up on the desk in the foreground.

Steve Trettel stands near a blackboard and a large screen displaying GLSL shader code. In the foreground, a laptop shows the same code and a resulting yellow and blue hourglass-shaped visualization.

For the fourth #illustratingMath day at the @cirm-math.bsky.social graduate school, we continue the mini-courses. In the #CindyJS course, we consider domain coloring to visualize complex functions. In the #Shadertoy course, we solve some PDEs and then render the game of life. (1/3)

Steve Trettel stands in front of a chalkboard and a projector screen. The screen displays a Shadertoy interface featuring a blue and white hyperbolic tiling and the title "73 Tiles."

Steve Trettel, a person with a beard and glasses wearing a red sweater, stands with one arm raised in front of a projector screen showing GLSL shader code in Shadertoy and a repeating pattern of white "F" shapes on a dark background.

A digital illustration of two black curved lines on a white background. Several small yellow circles (points) are positioned along the curves, suggesting a mathematical or geometric plot.

On day 3 of the #illustratingMath graduate school at @cirm-math.bsky.social, we continue the two mini-courses on #CindyJS and #Shadertoy. In the former, we learn how to draw conics (and how to draw them well). In the latter, it's all about hyperbolic tilings. (1/3)

A photo of a person standing in a lecture hall in front of a projection screen. The screen displays "CindyScript Basics" with bullet points about syntax, such as "Lines end with semicolons" and "Typeless." In the foreground, there are several boxes of colorful chalk on a wooden table.

A person looks down at a laptop in a lecture hall while a software interface titled "Cinderella" is projected on the screen behind them. The screen shows a geometric pattern of green dots arranged in a circular, spiral formation on a grid.

A high-contrast digital image of a Mandelbrot set fractal. The central "body" is black, surrounded by a vibrant, glowing pink and white halo that reveals intricate, repeating branching patterns.

A digital screenshot of a shader program displaying a complex yellow geometric pattern on a dark background. The pattern consists of intersecting circles and arcs that create a symmetrical, tunnel-like effect toward the center.

On the second day of #illustratingMath at @cirm-math.bsky.social, we continue the mini-courses #CindyJS and #Shadertoy: We tackled the scripting abilities of CindyJS and immersed ourselves in the creation of fractals and circle inversions, learning to write functions and structs in #GLSL. (1/3)

Baustelle 4: Ich arbeite seit vielen Jahren mit der dynamischen Geometriesoftware #CindyJS (siehe cindyjs.org). In ALICE:Bruchrechnen, der Toolbox Lehrerbildung und zahlreichen anderen Projekten und auch Vorträgen hab’ ich damit interaktive Visualisierungen erstellt.

Die Toolbox Lehrerbildung umfasst Grundlagentexte, Diagramme, Videotutorials (z. B. zur Cognitive Load Theory), gescriptete Unterrichtsvideos und interaktive Visualisierungen mit #CindyJS.
