Applications of 3D

3D in games
3D in games has evolved a lot over the years. Games started using 3D in 1981 with a game called 3D Monster Maze, this game would now be considered extremely basic however back then this game was considered revolutionary as it was the first game to use 3D the game it's self was a 3D maze with monsters in it and you get more points for the longer you survive if you get hit by a monster you die kind of like a 3D pac-man but without the pills it was quite basic in terms of gameplay and not remarkable however this opened up the idea to 3D games which is now an industry standard practice with 2D games become more rare by the years with most 2D games being made a 2.5D games 

Despite 3D monster maze 3D in games didn't really catch on until the fifth generation of consoles the big consoles of this generation were the Playstation, the Sega Saturn and the N64 these consoles were the driving forces of 3D with games such as Super Mario 64 the first Mario game in 3D and a lot of people regard this as one of the best mario games it took the traditional Mario formula of platforming and put it into a 3D environment adding features such as wall jumping and a full narrated story line and changed the way you progress from going through worlds until you beat browser to beating different stages to unlock stars so that you can beat bowser they were also allowed to add a lot more bonuses for completionests as they could add a lot more exploration than they could with a 2D game 
Another big 3D game on the N64 was Goldeneye this game was one of the games that created the first person shooter genera that we know today this is a game that lots of people look  back on today and still think is a very good game admittedly if you played it today it would feel clunky and horrible however for the time this game was very impressive and had some very impressive texture work for the time and was one of the fifth generation games that used 3D to the fullest of it's abilities
And now many years on 3D graphics have advanced a lot and become an industry standard practice with games such as skyrim boasting a full open world 3D game with graphics that were mindblowing for the time especially on the PC skyrim shows just how much both the technology to run games has improved and how much better people have got at using 3D technology back when people were astounded by goldeneye they would have never dreamed of a game such as skyrim they wouldn't have even thought a fully open world 3D game was possible and it wasn't on the hardware but with the evolution of gaming people are being able to do more and more with 3D and people are still inventing new 3D specific game mechanics to this day



3D in films and TV
The first time 3D was used in a film was in a 1976 film known as Futureworld which used a 3D rotating palm which was the first 3D animation  rendered in 1972 by Ed Catmull and Fred Parke. this wasn't exactly a revolutionary thing however it was a small taste of what could be done with 3D 



The first film to actually use 3D remarkably was the 1993 film Jurassic park this film featured full 3D animated dinosaurs and almost all of these were added in to the live action scenes using CGI this was quite a big part of the reason why this film was so successful because people had never seen anything like this before
A more recent example of 3D animation being used in films is Avatar this film is literately held up by it's use of CGI and the whole movie is a basically a showcase of what they can do with CGI this movie has some very impressive effects within it



Animation
Animation is a style of film possible because of 3D software studios like pixar use animation to make some very high quality films that are often said to be better than a lot of live action films


TV
3D was first used in TV in a show called reboot in 1994 this was the first 3D animated programme to air on TV it ran from 1994-2001 and because of this show 3D animated programmes on television are very common place and pretty much all you can find on children's TV

3D in education
3D is used in education to create models such as a model of heart for students to study if there doing biology or models of the globe for biology

3D in Medicine 

3D is used in medicine for CT scans they can create a model of the inside what they scan and then look at the inside and determine what's up with the patient

3D in engineering
3D is used in engineering to create a model of what they want to make before they make it and test certain pressures on the construction and see if it holds up




3D in architecture 
3D is used in architecture in order to make a model of the building before they actually build it

3D in product design

3D is used in product design to design the product that they want to make before they actually make it it allows them to consider things such as proportions and what materials would be best for what they are making

3D Printing

3D Printing is becoming a much bigger thing as time advances having it's own trade show and soon it's possible that we will have home 3D printers and they will become as common as the standard printer they are able to 3D print a lot of things already including art, food and even cars it's becoming a very big thing and will completely change the way things are made as it grows
