A 3D computer graphics is the process of changing over a 3D wire model frames into a 2D image that has a 3D realistic effect on a computer. There are different rendering processes that take place. There are real time and non real time, which is another phrase for Photo Realistic renderings. There is also reflection and shading. Reflection is the incoming and outgoing light at a certain given moment. Some of the most popular 3D renderings are Flat Shading, Gouraud Shading, Texture Mapping, Phong Shading, Bump Mapping and Cel Shading.

Shading is how different reflections are spread out over a surface. A good example of shading is called Texture Mapping. This uses an image that specifies the color at each section on the surface. Transport how light would move from one place to another. Projection is when a 3D object is made flat so the monitor that it is being shown on can be displayed in 2D.

Graphics have some really great applications and by learning then in your graphics tutorials you will learn how to use 3D renderings. With a little creativity you can go a long way.
