Understanding theories of 3D modelling

Understanding theories and applications 3D Modelling

In this report I will be giving examples of different uses of 3D modelling such as animation, TV, film, games, education and architectural walk through. I will be showing I understand how the models are displayed using colour, texturing, lighting, rendering and viewing. Then I will move on to talk about geometric theory and explain the modelling process and how we use the lines, curves and edges to create a 3 dimensional model and so on. Mesh construction and different 3D software’s will also be discussed with in this report then end on the problems I might encounter myself whilst creating a 3D model.

In three dimensional computer graphics, 3D modeling is the procedure of developing a 3D model using specialized software. It is a process of creating a wireframe model that represents a three dimensional object. That object can be alive or inanimate. A three dimensional model is created using a set of points in 3D space, which are connected by various geometric data such as lines, and curved surfaces.

3D modeling is so realistic and life like that it is used in mostly everything from film and TV to education and advertising, it’s hard to compare and notice which is real life and which is 3D modeling/CGI, here’s a showreel showing exactly how realistic and unnoticeable it is - https://www.youtube.com/watch?v=clnozSXyF4k&feature=player_embedded#at=27

Applications of 3D modeling – 

• ·      Animations are easier to create than constructing miniatures for effects or hiring extras for crowd scenes. It allows the creation of images that would not be feasible using any other technology. It also takes one graphic artist to produce content without the use of actors, expensive sets or props. Animation films such as Monsters Inc., Tangled and Frozen are all films that use full CGI. Animation can be used in advertising and music videos. Here’s a showreel showing different character animations - http://www.youtube.com/watch?v=UyRODPEEa_A
  
  
  
  
  
  
  
  ·      CGI was once only used within films but as the use of CGI has become cheaper its used in so many TV shows, its easier to use CGI than build a great big set, it allows for better camera angles and shots. Coronation Street, which is a soap, was the first show to use CGI in a live performance. Game of Thrones is a good example for the use of CGI, it’s a fantasy which is set in the medieval time period. Although they had built half the set they still used CGI to make it more realistic, they also used CGI for dragons. Here’s a VFX break down for Game Of Thrones - http://www.youtube.com/watch?v=imPwJ_AsVk8
  
  
  
  
  
  ·      CGI is used mostly in films that are futuristic or based in the past. Visuals scenes could be dynamic or static and may be 2D although the term CGI is referred to 3D modeling. Terminator 2 was the time where CGI became realistic and from then its just progressed and will keep progressing. Here is an example of how much CGI is used and how realistic it is - http://www.youtube.com/watch?v=H72IqJjP9l8. The Great Gatsby, which was released in the year 2013, was made all with green screen as the set and little actual set. -  http://www.youtube.com/watch?v=SLZ4_q85Ilc 
  
  
  
  
  ·      A virtual world can be created using CGI. Games can be created using 2D characters but the advanced gaming that is today is mostly 3D characters and a virtual world where the possibilities are endless. CGI in gaming allows the users to interact with the characters which means they will do whatever the user needs and wants them to do. Users are also able to play amongst other users, they see the game in the characters point of view then are able to see other users. Graphics and the CGI quality in games are increasing, technology is advancing and games are going to be life like, as if you are really in that virtual world.
  
  
  

  

  
        Grand Theft Auto 1997
        
         As you can see from this very first Grand Theft Auto game in 19997 the graphics are terrible and its a 2D birds eye view the whole game. When the game was released people thought this was amazing.
  
  
  
  
  
  
  
  
      Grand Theft Auto San Andreas 2004
      
       The graphics in this game from 2004 are greatly advanced from the first game but its still simple and produced more glitches. The sky's are plain and there isn't much detail.
  
  
  
  
  
  
  
  
  
  

  

        Grand Theft Auto 2008
  
        In the space of 4 years the details in the environment have changed and advanced, at this point everyone was amazed at the advance in technology for graphics.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  

  Grand Theft Auto V 2013

  
  

   In 2013 Grand Theft Auto V was released and the graphics are amazing, the attention to detail is perfect and it will get even better. It took 3 years to create and release this game due to the detail in the graphics.
