  • Once the basic game concept is decided upon, writers and artists work together on a storyboard. A storyboard consists of rough sketches and technical instructions sequentially organized to depict each scene of the game. It is a visual representation of the story. A video game can have thousands of outcomes.
  • Therefore various levels, or “worlds,” of the game must be sketched out.
  • As the storyboard is made, designers begin to create the characters. Rough sketches of major characters are drawn and redrawn until they are perfect. It’s important for the artists to refine the characters as much as possible at this stage because it will be difficult to make changes later.
  • Once the character design is finalized, it’s time to transform the sketches into controllable 3D characters.
  • Play Video
  • This can take up to 5 days per character expression.

  • The sketches are first scanned into the computer.
  • Then, a digital “exoskeleton” is created to define the character’s shape and to give the computer the control points necessary to animate the figure.
  • The game programmers bring this figure to life by instructing the computer to move the character. Several techniques can be used to do this, depending on the type of game and motion desired. In some games, the motions of a human actor are captured using a special suit of sensors to represent the control points of the character’s skeleton. These movements then can be mapped onto the character’s skeleton to produce ultra-realistic motion.
  • One of the most important aspects of modern game creation is the environment. Reflections in shiny surfaces and varied cloud patterns often go unnoticed by players, but they help create a much more natural environment.
  • The majority of 3-D objects created for computer games are made up of polygons. A polygon is an area defined by lines. Each polygon has a set of vertices to define its shape, and it needs information that tells it what to look like.
  • This allows games to have incredibly detailed 3-D environments that you can interact with in real time.
  • Unseen to the user, but making all of the game elements work together, is the code. Code is the set of computer language instructions that controls every aspect of the game. Most games are written with the C programming language.
  • A 3-D code engine is almost always used to generate the incredibly complex code necessary for all of the polygons, shadows and textures the user sees on the screen.
  • Once the game is complete, it enters the postproduction phase. This phase includes extensive testing, review, marketing and finally, distribution.
