Drawing Abrasive Hologram Animations with Auto-Generated Scratch Patterns

Abrasive holograms allow people to experiment with impressive quasi-holography and create hologram artwork through simple means of creating reflective scratches on sheets of plastic. Most of the reported accounts of abrasive holography address the creation of three-dimensional illustrations. This work explores abrasive holograms for creating arbitrary holographic animations through scratch patterns. The opportunities and limitations of scratch patterns are investigated. A model for classifying abrasive holographs is introduced. The classification framework is used to derive two new scratch pattern generation methods allowing the creation of arbitrary animations.
