@webloved: How I build with GPT-6 Astra 👇 Academy in bio 🔗 The particle membrane, how to make a cloud that holds a shape instead of drifting apart: 1. 40,000 points spawned inside a box, not a sphere. new THREE.BufferGeometry with random x y z inside your bounds 2. Move them with curl noise, not random. Sample simplex noise three times at offset positions and cross the results. That is what gives you those swirling fibres instead of static dust 3. Confine them: after every frame, if a point leaves the box, wrap it to the opposite face. The cloud now churns forever without spreading 4. Size by depth: PointsMaterial with sizeAttenuation true, size around 1.5, so front particles read bigger and you get real volume 5. Glow without lights: blending: THREE.AdditiveBlending, depthWrite false. Where fibres overlap they brighten on their own 6. One hue only, brightness does the work. Cyan at different alphas beats a rainbow every time Save this if you build for science and tech 🧪 #astra6 #buildinpublic #webdesign #webgl #fyp
