Printed Curtain Render

Workflow

1. Resolve the source image, optional text lines, palette, and output directory.
2. Resolve the installed skill directory and run scripts/createprintedcurtain.py.
3. Wait for VALIDATION=PASS and OUTPUT_HTML=<absolute path>.
4. Serve the output directory over HTTP and inspect the result in a browser. Do not use file://; browser canvas security can prevent local artwork pixels from being sampled.
5. Return the absolute HTML path, the local-server command, and the chosen artwork settings.

Quick Start

/usr/local/bin/python3 scripts/create_printed_curtain.py \
  --image "/absolute/path/to/artwork.png" \
  --text "VIBE MOTION" \
  --output-dir "$(pwd)/out/printed-curtain"

Installed Skill Resolution

Use the installed skill copy, not a source checkout of this skill collection:

skill_dir=""
for base in "${AGENTS_HOME:-$HOME/.agents}" "${CLAUDE_HOME:-$HOME/.claude}" "${CODEX_HOME:-$HOME/.codex}"; do
  if [ -d "$base/skills/printed-curtain-render" ]; then
    skill_dir="$base/skills/printed-curtain-render"
    break
  fi
done
[ -n "$skill_dir" ] || { echo "printed-curtain-render skill not found under ~/.agents, ~/.claude, or ~/.codex"; exit 1; }

/usr/local/bin/python3 "$skill_dir/scripts/create_printed_curtain.py" \
  --image "/absolute/path/to/artwork.png" \
  --text "VIBE MOTION" \
  --output-dir "$(pwd)/out/printed-curtain"

Preview

Serve the generated directory, then open the printed URL:

/usr/local/bin/python3 -m http.server 8000 --directory "$(pwd)/out/printed-curtain"

• Move the pointer across the curtain to push individual strands aside.
• Press H to toggle the live controls and image picker.
• Press R to rebuild the cloth.
• Drop a PNG, JPEG, or WebP on the canvas for a temporary in-browser replacement.

Customization

• Repeat --text to add multiple centered text lines.
• Use --image-fit contain|cover|stretch and the --image-x, --image-y, --image-width, and --image-height artboard controls to place artwork on the 1200×1600 material canvas.
• Use --text-y, --text-width, --text-height, --text-gap, --font-family, and --font-weight to refine type.
• Use --cloth-color, --ink-color, and --background-color with CSS hex colors.
• Use --overwrite only to update generated filenames in an existing output directory. It keeps unrelated files.
• Edit generated artwork.js for fine-grained image layers or per-line colors without forking the physics engine.

Behavior

• Copy the bundled p5.js simulation and the selected image into a portable output directory; do not upload user artwork or require a network connection.
• Bake artwork into the cloth's material coordinates so it stretches, folds, and separates with the strands instead of floating above them.
• Simulate 40 Verlet strands and interpolate the visible weave for a dense curtain at modest physics cost.
• Fit the stage to a centered 3:4 frame and preserve artwork proportions on other window shapes.
• Refuse a non-empty output directory unless --overwrite is explicit.
• Generate a text-only VIBE MOTION curtain when neither --image nor --text is supplied.

Requirements

• Python 3.9+
• A modern browser with Canvas support
