Task 1 - Applications of 3D

3D is becoming more and more popular within media as it is almost the next step in to the technological future by making things more realistic and all round experience enhancing. It has been almost 100 years since the first 3D film was made and still there are many technical problems with it and so it is not perfect however weather it be in games, film or tech; 3D is becoming more popular for people who want new exciting experience. It requires specialist equipment for making and watching which is why it is deemed to be so expensive.

3D used in Film

Film uses 3D in order to entice the viewer into the film itself and to feel more involved with it as they are almost part of it, this also in many cases makes it shocking and more realistic. Having said this, it comes with a price and costs more for the experience. However Avatar being one of the most successful film of its kind using 3D to connect the viewer into the fantasy world and be at one with the action. 3D is made by using models which doesn't need to be textured as that is done somewhere else, what makes it 3D is actually an illusion when wearing the glasses as the filters allow each eye to see the object/ 2D image at different angles making it appear to have a structure. This is known as stereoscopic vision. so when filming they film using 2 different lenses next to each other like the positioning of our eyes giving he same effect. It wasn't always done like that though, 'the adventures of shark boy and lava girl' was a 3D film that came out in 2005 and was filmed using one red filtered lens and another blue filtered lens that when 2 projectors were merged together and the filter glasses were worn, the images appeared 3D.

 

 

 

 

 

 

 

  

3D used in TV

TV has also incorporated the 3rd dimension but with these smart TVs you also have to buy specialised glasses. How it is achieved is similar to film as there are real life actors and so the TVs polarise the original in order to get separate images and again each of the lenses are directed to one of the images and the other focuses on the other one so essentially looking at 2 different screens with slightly different angles. One show that was premiered on sky and was available in 3D was David Attenborough's natural history museum alive, in which prehistoric animals came to life by 3D modelling which is an example of a slightly more complex 3D but the realist were amazing with the museum practically coming to life. Finally Darren Brown's 3D specular was on channel 4 available to watch in 3D but many people found that wearing the glasses can become irritating and give them headaches.
A new way of improving 3D TVs is their curvature which isolates the central image and acts as though what they are seeing is through their actual eyes.

 

3D used in Games

Games it is all constructed starting from a mesh which acts as the outline and a skeleton for the object. this is because they need to be intractable and nothing is worse than bad glitches where something just is 'ant down to grasps with everything else making it either un accessible or just annoying. additionally, the only 3D assets within games have to be closed polygons where as how many polygons are used depends on the gaming console or hardware rather than, than the game engine. having too many polygons will make the game hard to run and that is why new ways of making the environment graphics look ascetically pleasing and possibly intractable ie- grass that when u walk sways and adjusts to your footsteps whilst maintaining a low polygon count.

 

3D used in Design

3D design within the production of products is extremely useful as it means that 3D virtual models can be tampered with and even virtually tested which means that when it comes to physically making or building them, time isn't wasted as they already know the specs online, they can also examine any faults within the product or change it if it doesn’t look like they initially wanted it to, for example, when making a model they can see areas of weakness which can be adjusted so that either more material is there so that it is less likely to be damaged. Additionally, the models can be seen in a 360 degree world without spending money on resource in real life which they may not be able to use again. Finally, it means that the 3D model can be printed out, yes printed out with a special 3D printer which saves money as it doesn't take many people to operate a computer to send it to a printer and make sure everything goes smoothly! 

3D used in Medicine

3D is also now being used for medical purposes, for example in Spain a man who was suffering from cancer got treatment by having some of his body replaced with perfect fitting titanium sternum, this was achieved by them scanning his body to get the right dimensions and then re scanning where needed and thus they could see what was needed and reconstructed it. Along with this full prosthetic limbs are being made which is quicker and in the long run cheaper than the lengthy process it used to be. Finally when proceeding which surgery, they can use 3D technology to actually know how far away they are from something via the cameras inserted.
