10 More Copy-Paste Snippets: Real Physics on Canvas, Real 3D Models, and Scroll That Tells a Story
The easiest way to make a demo look impressive and be worthless is to fake the hard part. A "metaball" effect that's just overlapping blurred circles. A "3D configurator" that recolors a sphere instead of a real product. A scroll story where the text changes but nothing underneath is actually being measured. All ten snippets below refuse that shortcut on purpose: the metaballs are a genuine scalar field summed per sample point, the water ripples solve an actual discretized wave equation, the 3D pieces load real Khronos-licensed .glb models and compute their explode directions from real geometry, and the scroll stories measure a real SVG path length or a real clip-path percentage rather than eyeballing a number that happens to look right. Below are ten free, self-contained snippets spanning three lanes: hand-rolled Canvas 2D simulations built on real algorithms (flocking, metaballs, finite-difference wave propagation), Three.js scenes that load and manipulate gen…
