I initially thought this’d be about something like the space shuttle simulator, where they had electronics but no realistic computer graphics so they put an analogue video camera on a robot arm above a miniature scale model of the terrain around KSC and piped the feed to the screens in the simulator so that when the astronauts moved the controls the image they’d see would be accurate.,(reply>), Terrain model boards were used on t-37, T-38 simulators too. Very interesting with full motion systems,(reply>), He just did a video on this exact thing, but with tanks from the 70s,(reply>), @David H same,(reply>), I used something similar to that when I visited a German military base a few years ago, they used it for training tank drivers,(reply>), Wow, this is the future!
