Stereoscopic Layer Shifter (Inkscape Extension)

This Inkscape extension creates stereoscopic 3D images by shifting SVG layers left and right relative to a chosen "window layer".
It can export:

• Left and Right eye views (SVG or PNG)
• A combined side-by-side stereo view

🧩 Installation

1. Download or clone this repository.
2. Copy the folder hello_extension to your Inkscape extensions directory:
   • Windows: %APPDATA%\Inkscape\extensions
   • macOS: ~/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions/
   • Linux: ~/.config/inkscape/extensions/
3. Restart Inkscape.

🧠 Usage

1. Open your layered SVG file in Inkscape.
2. Go to Extensions → 3D → Stereoscopic Layer Shifter.
3. Choose:
   • The “window layer” (the reference layer that appears at zero depth)
   • Depth mode (max, moderate, conservative)
   • Export options (SVG / PNG / side-by-side)
4. Choose the path where you want to save your results.
5. Click Apply.

🛠 How It Works

• Layers in front of the window layer shift right (for left view) and left (for right view).
• Layers behind the window layer shift in the opposite direction.
• The shifts are proportional to depth:
  • max = strongest separation
  • moderate = medium separation
  • conservative = subtle depth
• Uses inkex.Transform() for accurate coordinate translation.

📤 Output

• left_view.svg / left_view.png
• right_view.svg / right_view.png
• stereo_side_by_side_layers.svg / stereo_side_by_side_layers.png
