🛡️ 100% Private & Client-Side

Unlike other tools that upload your personal photos to a cloud server, Filament Mafia Lithophane Engine runs entirely in your browser using WebGL and JavaScript. Your photos never leave your device. The 3D geometry is calculated locally using your computer's processor, ensuring maximum privacy and security for your personal memories.

🌖 The Science of Lithophanes

A lithophane works on the principle of variable light transmission. When you upload an image, our engine analyzes the Luminance (Brightness) of every single pixel.

• Dark Pixels = Thick Plastic (Blocks Light)
• Bright Pixels = Thin Plastic (Lets Light Through)

We map these values to physical thickness (usually between 0.8mm and 3.0mm). When you place a light source inside the printed sphere, the varying thickness modulates the light passing through, recreating your photo in high-resolution grayscale.

🖨️ 3D Printing Guide (Critical!)

To get the results shown in previews, you must follow these specific slicing rules:

🔧 Advanced Geometry Engine

This tool generates a "Manifold" (watertight) mesh. It automatically stitches a high-resolution displacement map (the outer surface) to a smooth inner sphere. It also procedurally generates a mounting cylinder compatible with standard LED tea lights or small bulb sockets. The "Resolution" slider controls the density of the mesh—lower numbers (0.15) yield millions of triangles for extreme detail, while higher numbers (0.30) print faster.

❓ Troubleshooting

"The preview is white?" — Yes, that is accurate. Unlit plastic is white. Use the "Preview Light" controls in the sidebar to simulate a bulb.

"File size is too big?" — High-resolution lithophanes contain millions of triangles. If your slicer lags, increase the "Resolution" slider to 0.25 or 0.30.
