Mirror Worlds

An interactive 3D book about digital twins, built for the Digital Twins lectures at the RITA Lab – Extended Reality & Digital Twins, IT:U (Interdisciplinary Transformation University Austria), Linz.

21 lessons in 8 topics: Foundations, Reality capture, Computer vision, Interoperability, Robotics, IoT, Smart farm kit (Keyestudio KS0567) and Validation. Each lesson follows predict → test → prove: students lock in a prediction, test it on an interactive 3D plate, then lift a flap for the answer, equations and code. Teacher's notes and APA 7 references are included.

Two display modes:

• 3D book: an open book with pop-up ink diagrams and turning pages
• Free 3D: the diagram alone on a dark drafting plate with glowing data flows
