For me it's an analytical process: I start by a round object ("ball") and try to figure out how the lines should be so that it can fit together. I remember (barely in my case, but that's because I'm not that into sport) that there is a difference between a football and a basketball, the football has pentagons and hexagons and the basketball has bigger shapes. I also remember the color, but not as picture, but as word, say "brown".

All this together and a bunch of more subconscious processing will result in a very bad picture of a basketball which wouldn't win a prize and probably would fail us another round of "guessing the picture".

OTOH, tell me about the structure of a house and how long something is, I can probably wind up a good 3d picture and even tell you how to walk around in the house. Maybe best described as "blueprint recognition".
