AI Analysis
●●SolidEye CandyWizardryCozy
500k interactive hair strands in WebGL, but utility stops at visual novelty.
Strengths
- •InstancedMesh rendering handles 500k strands without crashing browser tabs.
- •Custom GLSL shaders implement SMAA anti-aliasing at 5x native resolution.
- •Per-blade spring physics simulate wind and inertia efficiently on CPU.
Weaknesses
- •No documented API for reusing the moss component in projects.
- •Visual novelty lacks a practical use case beyond tech demonstration.

Post Description
Hi HN,
Sharing this technique I used to render 500,000 ray-traced-looking hair strands in real-time in the browser. And they also react to physics. If you create something cool with it, let me know! :)
