What it does

Build Wireframe Scan Reveal is an agent skill from nirholas/three.ws. Reveal Three.js geometry with an expanding world-space scan whose wire cage leads the solid surface, then burns away. Use for wireframe scanning, radial mesh reveals, survey pulses, holographic assembly, topology intros, and 3D model entrances where a plain opacity wipe does not explain the form.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files (for example `agents/openai.yaml`, `demo/PROMPT.md` and `demo/assets/three.min.js`).

It sits in Frontend & Design, covering UI design and 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

When your agent uses it

  • Wireframe scanning
  • Radial mesh reveals
  • Holographic assembly
  • Topology intros

Example prompts

  • “/build-wireframe-scan-reveal”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 66624fb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (JavaScript), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Wireframe Scan Reveal loads about 1.6k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 758 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Reveal Three.js geometry with an expanding world-space scan whose wire cage leads the solid surface, then burns away. Use for wireframe scanning, radial mesh reveals, survey pulses, holographic assembly, topology intros, and 3D model entrances where a plain opacity wipe does not explain the form.

Build a Wireframe Scan Reveal

Make one world-space wavefront conduct both representations: draw topology at the front, hold the solid behind it, then remove the temporary cage. Reach for technical-wireframe-info-layout when wireframe is the page's permanent visual language; reach for animation-on-scroll when the conductor is DOM scroll rather than a 3D wave.

Extracted from inner-green-3d.html, where a survey pulse had to grow a procedural moss root through cards and type without reading as a circular mask.

Pair two representations

Create the solid mesh and a temporary LineSegments cage from the same source geometry. Share uScanOrigin, uScanRadius, and time between their materials. Keep both in world space; local-space distance changes when a group is scaled or nested and tears the two fronts apart.

Discard the solid beyond the front, with a lag that leaves the cage visible first:

glsl
uniform vec3 uScanOrigin;
uniform float uScanRadius;
uniform float uScanEnabled;

bool unscanned(vec3 worldPosition, float lag) {
  if (uScanEnabled < 0.5) return false;
  float wobble =
      sin(worldPosition.y * 0.011 + worldPosition.x * 0.007) * 36.0
    + sin(worldPosition.z * 0.021 + worldPosition.y * 0.013) * 17.0;
  return distance(worldPosition, uScanOrigin)
       > uScanRadius - lag + wobble;
}

// In the solid fragment shader:
if (unscanned(vWorldPosition, 520.0)) discard;

Use one origin outside the silhouette, usually low and left. A centered origin reads as a loading ring. Keep the two long sine terms; a perfectly circular front reads as a clip-path, while high-frequency noise makes the edge sparkle.

Make the cage ride the front

Measure each line fragment against the same radius:

glsl
float distanceFromOrigin = distance(vWorldPosition, uScanOrigin);
float rim = exp(-pow((distanceFromOrigin - uScanRadius) / 135.0, 2.0));
float trail = smoothstep(uScanRadius, uScanRadius - 950.0, distanceFromOrigin);
float alpha = (rim * 1.60 + trail * 0.34) * uWireOpacity;

Use additive blending, transparent: true, depthWrite: false, and a pale version of the scene accent. Keep depth testing on unless the cage must read through the object. Turning depth test off exposes the back half of dense topology and produces a bright unreadable ball.

Animate one conductor

Use the landed timing as a starting point:

parameterdefaultfailure prevented
duration3.4 sa fast reveal reads as a flash
radius easing1 - (1 - t)^1.35linear travel stalls visually near the far corner
solid lag520 world unitszero lag makes wire and fill arrive as one wipe
rim width135 unitsa narrow rim aliases; a wide rim becomes fog
wire trail950 unitsno trail hides topology before it can be read
wire fadesmoothstep(.72, 1, t)persistent cage competes with the finished surface
radius reachscene diagonal × 1.3 + 900the far corner remains clipped after completion

Snap the cage on over the first 6% of the timeline, then fade it during the final 28%:

js
const e = Math.min(1, elapsed / 3.4);
scanRadius.value = easeOutPow(e) * maxRadius;
wireOpacity.value = Math.min(1, e / 0.06) * (1 - smoothstep(0.72, 1, e));

At completion, disable the discard branch, remove the cage, and dispose its geometry and material. Hiding it with opacity leaves duplicate geometry and shader work alive for the rest of the page.

Stage and size the scan

Resolve maxRadius after layout and after parent matrices update. Use a ResizeObserver, guard zero-sized roots, update the camera projection, then recompute the origin and farthest reach. A one-time measurement before fonts or layout settle leaves the last corner unrevealed.

Keep the demo's scene recognisable: grey-green field, bottom light pool, white editorial type, pale cards, and the root-shaped form. The staging belongs in the demo; the reusable skill is only the paired representations and shared conductor.

Respect motion and lifecycle

  • Under prefers-reduced-motion: reduce, render a designed diagnostic still at about 62% radius with both cage and solid visible. Let the replay control recompose that still and announce the state; do not hide the scene.
  • Clamp dt to 1/30 s. Reset the time base after a hidden tab or offscreen section resumes.
  • Pause on document.hidden and when an IntersectionObserver says the section is offscreen.
  • Cap device pixel ratio at 2.
  • Expose replay as a real button with visible focus and an aria-live status. Keep the canvas aria-hidden when it is decorative.
  • On teardown, cancel the frame, disconnect observers, remove listeners, and dispose geometry, materials, textures, and the renderer.

State the cost honestly

The temporary second representation and its line coverage are the real cost. Topology density and overdraw matter more than the radius math. Build the wire cage only for the entrance, use the coarsest edge graph that preserves the silhouette, and dispose it as soon as the scan finishes. Do not claim a performance gain without profiling GPU frame time before and during the cage pass.

Verify

  • Compare the opening, midpoint, and completed states with the source at 1440×900.
  • Confirm the cage leads the solid everywhere, including scaled child groups.
  • Fast-forward across completion and verify no clipped islands remain.
  • Replay twice and confirm only one frame loop and one cage survive.
  • Resize during the scan at 390×844 and 1440×900.
  • Tab to replay and confirm visible focus and a live status update.
  • Test ?reduced=1 or system reduced motion: composed still, no advancing radius.
  • Hide/show the tab and leave/re-enter the viewport; confirm no time jump.
  • Confirm a clean console and disposed cage resources after completion.

Use demo/index.html as the working proof and demo/PROMPT.md to recreate or remix it.
