Description
What is this
A 400-year-old optical trick: cylindrical mirror anamorphosis. The board carries a ring of warped, unreadable linework. Stand a mirrored cylinder on the placement circle and look from the calibrated height and distance — the pattern resolves into an upright image on the cylinder.
✨ Highlights
- Live 3D mirror preview — switch to the mirror view and check the result on screen before cutting anything
- 5 built-in examples, or upload your own image (JPG / PNG / WEBP / SVG); greyscale and contour processing modes
- Every parameter adjustable: mirror diameter and height, eye height and viewing distance, drawing size and wrap angle — the preview updates instantly
- The placement circle is engraved on the board; the viewing height and distance ship in the bundled README, so the piece works as a gift
🛠 How to use
- Upload an image, or pick a built-in example
- Enter your mirror diameter (measure any polished steel tube you have) and viewing posture
- Switch to the mirror preview to verify the result
- Click “Check and export”
📦 Export files
- Laser, contour mode: layered SVG — placement circle (light engrave, never cut through) and vector artwork; operations carried by layer id, not stroke colour
- Laser, greyscale mode: two 600 DPI engraving PNGs to pick one from — plain artwork, or artwork with the placement circle baked in
- UV print: true-size 1:1 PDF and 300 DPI PNG (with bleed), optional white-ink layer
- Every bundle includes a 1:1 instructions PDF (placement circle, dimensions, viewing guide) and a README
🧰 Materials
Any sheet you can engrave or print on: basswood or birch plywood is the usual choice; light-coloured acrylic and cardstock work too. The mirror needs no machining — an off-the-shelf polished stainless-steel tube does the job (φ20–50mm is common; enter the diameter in the panel).
