Lichtenberg generator

Procedurally generate realistic 3D Lichtenberg figures (fractal electrical discharge trees) tailored for subsurface laser inner engraving in optical crystal blanks. Designed specifically for xTool Studio and the xTool F2 UV laser.

Feature Highlights

• Realistic Dielectric Breakdown: Simulates natural high-voltage lightning discharge using 3D dielectric shortest-path graph physics.
• Parametric Crystal Volumes: Matches Box, Sphere, and Cylinder crystal blanks with adjustable dimensions (W$W\times D\times H$×D×H in mm) and configurable safe edge margins.
• Dual Discharge Origins: Choose Center for a 360° radial burst or Base for a natural upward-branching lightning tree.
• Illumination Preview: Preview your crystal on simulated Cool White, Warm Amber, Electric Blue, or Darkfield LED light bases.
• Slicer-Ready Exports: One-click export to .3mf, .stl, or .obj pre-aligned upright for immediate import into xTool Studio.

Supported Materials

• K9 Optical Crystal: Recommended for highest refractive index, clarity, and brilliant micro-fracture contrast.

• K5 Optical Crystal: Fully compatible budget-friendly alternative with smooth fracture responsiveness. 

Usage Steps

1. Set Blank Dimensions: Select your crystal blank shape (Box, Sphere, Cylinder) and enter its dimensions (W$W\times D\times H$×D×H in mm).
2. Customize the Lightning: Pick an origin point (Center or Base), adjust branch density, trunk thickness, and jitter noise, or click Roll for a new seed.
3. Preview Illumination: Test your design under different LED pedestal light modes to check internal balance and contrast.
4. Export to xTool Studio: Choose your format (3MF, STL, or OBJ) with xTool (Upright) orientation and import directly into xTool Studio for inner laser engraving.
