As the majority of what would be covered can’t be seen or captured on camera – how signals move across wires, how heat/motion/sound sets off sensors etc – we decided that 3D animation would be the best approach.With the ability to place the camera anywhere from the macro to the micro; to switch between electromagnetic spectrums at any point and to show objects either as hologram outlines or full 3D renders, allowed us to fully demonstrate how these technologies work.
