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.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'webgl-raymarched-hero' ] || [ -L ~/.agents/skills/'webgl-raymarched-hero' ]; then echo 'A skill folder named webgl-raymarched-hero already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nexu-io/open-design' "$d" && git -C "$d" checkout --quiet '614795896e09a2c1682b24cc1406529baf531bd7' -- 'plugins/_official/examples/webgl-raymarched-hero' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/_official/examples/webgl-raymarched-hero' ~/.agents/skills/'webgl-raymarched-hero' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'webgl-raymarched-hero' ~/.claude/skills/'webgl-raymarched-hero' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
