By nexu-io. Updated August 18, 2026. Categories: Debugging.

A real-time raymarched 3D hero — soft-shadowed morphing metaballs with a fresnel rim light, sphere-traced per pixel in a fragment shader with a slow camera orbit. No meshes, no textures. Rendered as a single self-contained `index.html`. Use when the brief asks for a "raymarch", "signed distance field", "SDF", "3D hero", "metaballs", "blobs", or a shader-based 3D scene. OpenDesign serves this in powered-preview mode so the GPU stack actually runs.
