Oh yes - for pretty much everything I look at for longer than 5 seconds now, my brain will be overlaying virtual polygons and auto-suggesting edge flow and all-quad topology options. I look at trees, and see L-systems, I look at the ocean and wonder about fluid solvers, and when I see sunsets and clouds I wish the Physical Sky was better :) Whenever I find myself somewhere truly beautiful I still manage to hold on to that sense of awe at nature, but at the same time, my brain is also very much working out how we might get an HDRI of that :)
Seriously though - I suspect 3Ding is like musicianing, in that it gets certain parts of the brain practiced at thinking a certain way, and doing activities like music or 3D will of course open up new pathways, possibilities and ways of thinking as you improve your skills. I never used to be able to see 20 moves ahead when modelling for example, but years in Cinema has slowly retrained my brain to be able to do that. Indeed it has also increased my precision and general levels of diligence and technique, and I am now programmed to enjoy efficiency of action and an immaculately organised Object Manager in a way that was positively alien to me when I started.
On the negative side, I have never seen anything that comes close to the massive periods of lost time that can happen when you are 'on one' in 3D. The amount of times I have thought to myself at 7 pm one evening 'Oh, I'll just pop in there and tweak that topology for 10 minutes', and then there's the dawn, and 15 hours have mysteriously disappeared. Can't believe I'm the only one that happens to !! :)
