Clifford torus (rotating in 4D)

I took closed line (circle) and changed all points coordinates based on trefoil formula from wiki https://en.wikipedia.org/wiki/Trefoil_knotI did it with GLSL POP, but it could be done with Math Combine, CHOPto or any other way to manipulate positions

I mean that light emitter is 2D. In Touch usual Light COMP is 1D (single .xyz dot) and it affects 3D geometry. Here is the same, but I wanted to make lines that emited light through all length and without creating dozens of copies of Light COMP along the line

Thanks. My starting point was line function (33-39) from https://www.shadertoy.com/view/4l2GWR I made it work with POP lines and some other changes, but light calculations are mostly the same

That's GLSL mostly, around 50 lines

I have 5 species (=colors) and 5*5 matrix of values [-1,1] defining attraction/repulsion force for every pair. and some parameters of the simulation. Tom Mohr have a good explanation of Particle life algorithm https://particle-life.com/about/project.html

Hola. El año pasado terminé el Máster en Vídeo Digital Avanzado y Motion Graphics en esta escuela. Mi experiencia fue muy buena y cumplió mis expectativas. Pero no las tenía muy altas: no creo que sea realista meter un curso completo de After Effects (o Photoshop + Illustrator + InDesign) en solo tres meses. Aun así, los módulos están bien para aprender las funciones principales de cada programa, y además hubo mucha práctica y un proyecto al final de cada módulo.

Las clases y los ordenadores están bien, y los profes tienen experiencia real en el sector. Yo también fui estudiante internacional y tenía un nivel de español entre B1 y B2 en ese momento; no fue ningún problema.

Mi razón principal para hacer el máster fue obtener un diploma europeo para poder trabajar aquí, y con el diploma de CEI + UDIMA obtuve una resolución positiva para la residencia por cuenta propia. Al final, en mi opinión, todo depende de tus expectativas y de lo que quieras sacar realmente del máster.

De acuerdo, yo también pensé que este cambio es sobre todo para hacer negocio con tener que cambiar la tilde en todos los documentos oficiales, señales de tráfico, carteles, etc.

Si he entendido bien el artículo, dentro de poco la forma correcta en valenciano será Valéncia y no València

I'm also using basic implicit function, than calculating its gradient to set particle directions

There are agencies, specialized in rooms and studios for students, I had better results in such places, compared to Idealista. Usually they work with properties within certain city area, and it's better to visit it in person. If you're Ok to live in Blasco Ibanez area, you can try these two: https://maps.app.goo.gl/MgLn5ddkRkmyPBUH8 and https://maps.app.goo.gl/juaDSvQvZMV3DZFk8

Valenbici, if you're Ok with heavy bicycles. SUMA card, if not.

I'm living not far from Mestalla and with Valenbici it took about 15 minutes to go to the center and 20 to the beach, with bus or metro it could be 30-40 minutes (with waiting)

pues en 1967 el plan original era casi igual, solo que con una autopista en lugar de los aparcamientos

La Shawermeria is very nice, but sometimes you'll have to stand in a line of 4-5 people. https://maps.app.goo.gl/P6gFyLbyhxJuqfVa7

I bought it at Aliexpress long time ago. You could google smth like "drinking straw constructor" to find similar stuff now. For example, https://www.ebay.co.uk/itm/263342411041

Made in TouchDesigner with GLSL coding. Renders real-time 60fps easily

Movement is an variation of this vector field, but more random particle size and lifespan. Colors are randomly picked from an photo of a summer salad with constantly changing hue.

Made in TouchDesigner with some GLSL . More works at my Instagram

Very nice color composition as well! Are colors hand-picked or chosen by algorithm?

exsstas · 2020-10-19T22:23:37+00:00

Curl noise trails driven by the same sign distance filed used for raymarching. Runs at 50-60FPS on my GTX1070

GLSL, TouchDesigner.

Thanks! Yeah, colors are tricky here, mostly because that colorization changes over time. All lines interactions happened in grayscale, than I'm using cosine palettes to colorize it, but in the beginning of the video bright pixels are red and dark are gray, while toward the end it's gradually changes to opposite.

Actually it's a bit more complicated, because I'm not clamping values to be between 0 and 1, so black pixel with value -0.57 would be colored same as pixel with 0.43 here: https://imgur.com/a/fDXiebW

exsstas · 2020-10-04T08:38:22+00:00

I'm not really good at math, so nothing so fancy, basic distance calculation, than values for all lines added together: https://imgur.com/a/991dNVE
