                    Definition
   3D computer graphics are works of graphic art
    that were created with the aid of digital
    computers and specialized 3D software. In
    general, the term may also refer to the process
    of creating such graphics, or the field of study of
    3D computer graphic techniques and its related
    technology.
    Creation of 3D computer graphics
   The process of creating 3D computer graphics
    can be sequentially divided into three basic
    phases:
     Modeling
     Scene layout setup

     Rendering
                       Modeling
   The modeling stage could be described as
    shaping individual objects that are later used in
    the scene.
   Modeling processes may also include editing
    object surface or material properties, adding
    textures, bump-maps and other features.
       The model is a description of three dimensional
        objects in a strictly defined language or data
        structure. It would contain geometry, viewpoint,
        texture and lighting information.
                Scene layout setup

   Scene setup involves arranging virtual objects,
    lights, cameras and other entities on a scene
    which will later be used to produce a still image
    or an animation.
   If used for animation, this phase usually makes
    use of a technique called "keyframing", which
    facilitates creation of complicated movement in
    the scene.
                      Rendering
   Rendering is the final process of creating the
    actual 2D image or animation from the prepared
    scene. This can be compared to taking a photo
    or filming the scene after the setup is finished in
    real life.
       Rendering is the process of generating an image
        from a model, by means of a software program.
