As to this specific design, there’s some info on this inside the archive. To quote:
Here’s the sketch by Ken Adam that the 3D environment is based on. It’s amazing that they actually did that, especially if you consider how rough and abstract Adam’s sketch is. It’s cool that they even left it in black and white. My favorite detail about this one, by the way, is that they made that large glass tube a (functioning) lift to the upper level. Pretty cool.
I’ve been staring at this concept drawing since I was a child and looking at it in my Art of
Star Trek book. Seeing it come to life like this is … wild. I’m still can’t quite grasp that they actually did that.
