💡Pen Plotters Create Unique Holograms Unachievable by Printers
Holograms Made Easy with Pen Plotters and Olive Oil?
TL;DR
A pen plotter can create holograms that printers or hands can't. The author uses olive oil to grease fingers for better results, but the perfect material is still being tested.
A pen plotter can create unique holographic images unachievable by traditional printing methods. This technique relies on reflective ridges with curvature inversely proportional to point distance from a camera, calculated using math and stored in GitHub code. The author found old CD jewel cases work well for making holograms but is still experimenting with materials like clear plastic sheets and wooden styluses.
Key Points
Each point in a 3D scene becomes a reflective ridge, inversely proportional to distance from the camera (Fact 5).
Math calculates each point's position on the surface as hyperboloid sections for holograms (Fact 6).
GitHub hosts the author’s code for making holograms with pen plotters and olive oil (Fact 7).
Clear plastic sheets and wooden styluses didn't work well, but CD jewel cases did (Facts 8-9).
Light source must be a point-source; main glare should be just above etches for best effect (Facts 10-11)
Why It Matters
DIY enthusiasts can create holograms using pen plotters and common materials like CD jewel cases. The technique relies on precise calculations and reflective properties, stored in GitHub code. This opens up new possibilities for hobbyists and artists to explore complex optical illusions without high costs.
