Sheezus...some people just read what they want...obviously context and comprehension do not exist around here...I'll try this again and read verbatim.
It is physically impossible to have depth perception with one image source. It is therefore impossible to have accurate depth perception of in-game objects with just a computer monitor. I could engineer any number of viewing scenarios in which a proper stereo image would make the difference in assessing distance to an object. Hint: how can you know whether an object is large or just very close to you?
So you don't misread or misquote me again...in the 3D realm of AH
depth is fairly well modelled <---note that the words accurate or actual do not exist in the previous statement...obviously there is no literal depth perception as seen in the real world and not one person in this discussion said it does exist. However if depth perception were not
emulated in some way in AH, it wouldn't be 3 dimensional and few people would be able to land a plane on a runway or ship without tearing up their aircraft or running into something...but AH is a 3 dimensional environment and as such depth has to be
simulated in order to achieve that...for those harping on stereoscopic vision, try looking up stereoscopy or stereoscopic imaging.
any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image
Almost everyone playing AH has a brain that is functional and that brain has the capacity to memorize...it also has the ability to associate...and with those two capabilities I can train my brain to associate relative approximate distances to objects within AH without having to see icons...so can anyone else with a functional brain.
Obviously no one could jump into the scaled down 3D world of AH and be able to determine distances in the same manner they do in real life without some point of reference within the environment, hence the reason icons with distance indicators exist...however, just like real life we can train our brains to determine distances within the 3D realm of AH exactly the same way we learned how to determine distances in the real world...perhaps that may not be possible for everyone but I'm being optimistic and giving the benefit of the doubt that everyone in AH has a functional brain...since we do not live in the 3D realm of AH and cannot touch, feel or smell the environment the time it takes to learn how to determine distances based only on visual cues would be determined by the amount of time a person spent training themselves to do so, under normal circumstances. The process of training oneself to determine approximate distances without visual cues or actual depth perception in AH is not convenient nor easy while trying to fly a cartoon airplane...you have to use zoom in varying degrees, turn the icons on/off repeatedly, and memorize what you see from every angle available.
Since AH is a 3 dimensional simulated environment and there are limitations and real life depth perception does not exist...determining altitude over a flat surface where few if any vertical structures exist such as water is nearly impossible...and since objects are rendered in pixels there are obvious limitations as to how far away an object gets rendered with enough detail to determine anything more than dark dots...but we can learn to determine approximate distances within the limitations of the 3D environment by memorizing and associating.
