The generation of prime numbers into weight × level + jump (animation - three.js)
Experimental for now (only natural and prime numbers) but soon this animation will be added to the 1000 sequences of my site.

Finally getting arcAngle from arcLen & chordLen working using Inverse Sine Cardinal, took 6 yrs. Now I can improve one of my IK solvers & get a starwars AT-ST doing walk cycles from human animations :)

Wir suchen jemand der 2 flächige Vektorgrafiken mit #ThreeJS animiert.
1. Schriftzug
2. Eine Sonne (nur die Strahlen)
Im Raum drehen und maskieren
Soll Responsiv auf Mobil und Desktop gut aussehen
Schwarz und Transparent
keine Lichtquellen.
Gerne boost!

Today we have a brilliant new demo by Deadrabbbbit for you! 
It's a super cool scanning light effect built with WebGPU, depth maps, and custom shaders using Three.js and R3F.
Check it out: https://tympanus.net/codrops/2025/03/31/webgpu-scanning-effect-with-depth-maps/

Got a little project I'd like to share.
It's a interactive portfolio book that will show off some of my works. Right now it's still in development.

Painthead. https://davideprati.com/demo/painthead/ drawing application developed with #threejs #webgl #shaders . It uses 3d meshes as a paint brush and an ortographic camera.
