Animation

Three-dimensional computer graphics (3D computer graphics, in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be stored for viewing later or displayed in real-time.
3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and 3D may use 2D rendering techniques.
3D computer graphics are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences: a 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is displayed. A model can be displayed visually as a two-dimensional image through a process called 3D rendering or used in non-graphical computer simulations and calculations. With 3D printing, 3D models are similarly rendered into a 3D physical representation of the model, with limitations to how accurate the rendering can match the virtual model.

The animation is a unique field in the sense that it is a blend of creativity and technology. So if you have a mindset of applying technology and use your creativity then animation course can open up really exciting and rewarding avenues for you. Animations be it simple drawing, 2D and 3D imaging are now widely used in media and technology world. As you have seen the latest movie, Avatar, it is just an ultimate use of animation technologies. Now, they are also increasingly used for product designs, stall designs, automobile designs and so on. So if you think you have good drawing and creative skills and have a bend toward learning technologies, go for this.
You can have good jobs in animation area as this field is progressing day by day and there are huge chances for success and high job profile mainly in metropolitan cities.
If you want to learn designing then you should do this from high profile institutes and cities because this field requires immense exploration of ourselves and our mind. It basically searches for innovation and creativity.
