Are there books on training visual imagination?

This article is why:

>What made Nikola great was his precise and grandiose imagination. He grew up with an intense visual imagination that tormented him when he was unable to control it. It would present itself forcibly unto his mind when he was trying to interact in the real world. He grew up without confidence in himself thinking that this was a shackle destined to cripple his life-long worth and validity. But he learned to control it. And for all the pain he suffered, the sheer beauty of the upside is hard to match. I could do no better to describe it than he:

>“I soon discovered that my best comfort was attained if I simply went on in my vision further and further, getting new impressions all the time, and so I began to travel; of course, in my mind. Every night, (and sometimes during the day), when alone, I would start on my journeys – see new places, cities and countries; live there, meet people and make friendship and acquaintances…

>This I did constantly until I was about seventeen, when my thoughts turned seriously to invention. Then I observed to my delight that I could visualize with the greatest facility. I need no models, drawings or experiments. I could picture them all as real in my mind… I do not rush into actual work. When I get an idea, I start at once building it up in my imagination. I change the construction, make improvements and operate the device in my mind. It is absolutely immaterial to me whether I run my turbine in thought or test it in my shop.”

I know Tesla was kind of known for his self-indulgent hyperbole, but is this obtainable? I have a pretty good imagination myself but how does a person step over that hurdle and get to that level?

Obviously, I am asking this with a focus on its application in art.
