Modelling
In 3D computer graphics, 3D modeling is the process of developing a mathematical representation of any three-dimensional surface of object via specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D Printing devices.

Texturing & shadings
Rendering is the process of generating an image from a model (or models in what collectively could be called a scene file), by means of computer programs. A scene file contains objects in a strictly defined language or data structure; it would contain geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" may be by analogy with an "artist's rendering" of a scene.

Lighting
The lighting in a scene is one of the most difficult things to get right, and deserves close study for anybody serious about model¬ling and animation. Basic.lighting consists of ambient light - a general light present, such as the light from a cloudy sky - and then specific lights placed in a scene. Again, there is some considerable variety in the control you have over these lights, but this is not quite enough for realistic effects. A scene using standard lighting techniques simply looks rendered. Those images that are the most realistic use advanced techniques such as ray tracing and radiosity.

Matte-Painting
A matte painting is a painted representation of a landscape, set, or distant location that allows filmmakers to create the illusion of an environment that would otherwise be too expensive or impossible to build or visit. Historically, matte painters and film technicians have used various techniques to combine a matte-painted image with live-action footage. At its best, depending on the skill levels of the artists and technicians, the effect is "seamless" and creates environments that would otherwise be impossible to film.

Rigging
Rigging is the mechanical sailing apparatus attached to the hull in order to move the boat as a whole. This includes cordage, sails , and spars . Cordage is more usually the term for stocks of rope, yarn, or other types line in storage, before it has been put to some use in a vessel, whereafter is commonly referred to as the rigging. In this article, Rigging denotes the full set of cordage, sails and spars, except when it is part of another term.

Animation
Computer animation is the process used for generating animated images by using computer graphics. The more general term computer generated imagery encompasses both static scenes and dynamic images, while computer animation only refers to moving images produced by exploiting the persistence of vision to make a series of images look animated. Given that images last for about one twenty-fifth of a second on the retina fast image replacement creates the illusion of movement.

Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film.

Dynamics
The Center for Element and Complete Design Modelling (CEMEK) of the Faculty of Mechanical Engineering at the University of Ljubljana in Slovenia has developed a mathematical model for the simulation and analysis of the driving dynamics of road vehicles. The model allows for the reconstruction of vehicle motion immediately before a traffic accident with a simultaneous analysis of the driving and control dynamics. The model is based on the data that is usually available at an accident scene and allows for a reasonably accurate reconstruction of the accident.
