Twisting hollow sculpture drawn as fine visible wireframe lines on pale paper

A parameterized loft builds a twisted three-dimensional mesh. A triangle depth buffer rejects occluded samples from its ribs and rings; face-facing changes add stronger silhouette lines, while visible depth controls line weight and tone. The default sculpture, camera views and exports are calculated locally without a generation service. Higher rib density and output size increase local work; a new concept reference is optional and does not replace the geometry.

What you get

  1. Sculpture PNG and editable visible-path SVG

  2. Depth-buffer proof image

  3. Mesh and camera ledger with portable brief

Good for

  • Architectural line-art prints
  • Sculptural geometry and camera studies

Not for

  • Recovering a real object from a photograph
  • Fabrication-ready solids or physically plotted proofs

How it works

Includes a local renderer

  1. Choose the input

    Set the sculpture twist, rib density and camera.

  2. Render and inspect

    Project the mesh and remove hidden line samples.

  3. Adjust and export

    Compare the depth proof with the ink drawing before exporting paths.

How the workflow runs

How Wireframe sculpture print works

A parameterized loft builds a twisted three-dimensional mesh. A triangle depth buffer rejects occluded samples from its ribs and rings; face-facing changes add stronger silhouette lines, while visible depth controls line weight and tone.

What's inside the skill

What you can change

  • rib_count: 20–90 longitudinal ribs
  • twist: −0.2–3 radians per normalized height
  • camera_azimuth and camera_elevation
  • background, ink and output dimensions

What to review before delivery

  • Both visible and occluded line-sample counts exceed 1000 in the examples.
  • The mesh contains exactly rib_count × 110 vertices.
  • The saved brief reproduces the PNG and SVG; unsafe replacement is rejected.

Why use this skill

Start with this package

The package already connects mesh construction, hidden-line testing and vector export. A plain wireframe screenshot would retain hidden edges and would not supply editable visible paths.

A prompt, your own skill, or this workflow?

Start with a prompt

Your agent can create from a plain request. The brief, visual rules, asset choices, output format and review process still need to be established for that project.

Write your own skill

You choose and maintain the reusable instructions, defaults, file structure and checks. This is useful when your process needs different rules or integrations.

A workflow created for PopNow

This workflow was built for PopNow. Its source files, included dependencies and applicable notices are part of the package; the scope described below belongs to this edition.

What will this cost?

The default sculpture, camera views and exports are calculated locally without a generation service. Higher rib density and output size increase local work; a new concept reference is optional and does not replace the geometry.

The supplied route runs locally. A new-media request is a separate choice. Free skill. New media is quoted before it runs.

The skill package

Free to install under your account's download allowance. The package license covers your own and client work; redistribution is excluded.

Existing assets and local work

Reusing suitable assets, editing files and running local assembly do not call a PopNow generation model. Your computer and any required runtime still do the work.

Your agent and hosting

Any subscription, hosted computer, deployment or other provider fee belongs to that service. Installing this skill does not include those services.

How PopNow billing works

Connections using a PopNow API key, including API-key MCP connections, spend from the separate API balance in USD. A ChatGPT or Claude connection authorized through OAuth spends website credits. These balances are separate; the quote shown by your connection is the approval basis.

Download allowances and current account conditions apply. A free package does not mean unlimited free generation.

How to use it

You say

  • Use the PopNow skill "Wireframe sculpture print" (wireframe-sculpture-print) for this: Set the sculpture twist, rib density and camera. Use the packaged example as a starting point and return the actual artwork with its editable inputs.

Then try

  • Rebuild a visibly different version using twist: 1.45 → 2.2; camera_azimuth: 32 → 75.

  • Explain the result using its actual proof files and algorithm ledger.

What to have ready

  • The desired twist, rib density and camera angle
  • Python 3.10+, Pillow and NumPy

Questions

Does it actually calculate visibility?

Yes. It rasterizes the mesh into a depth buffer, tests line samples against that buffer and adds silhouettes where adjoining faces change facing direction. Very fine detail remains limited by the declared visibility-buffer resolution.

Is the SVG a screenshot of a mesh?

No. The main SVG contains the visible line paths. The separate depth-proof PNG helps inspect the hidden-surface calculation; the geometry JSON preserves the mesh and camera.

What costs depend on this workflow?

The default sculpture, camera views and exports are calculated locally without a generation service. Higher rib density and output size increase local work; a new concept reference is optional and does not replace the geometry.

What is already packaged in Wireframe sculpture print?

The domain algorithm and invariant checks. Runnable, editable example parameters. Control meanings, proof interpretation and limits.

Which parts of Wireframe sculpture print can add a charge?

How does Wireframe sculpture print differ from writing a prompt or my own skill?
