Tell me about 3d Graphics
3d Graphics are graphics that use three dimensions to represent the geometry data that is used for the actual calculation and rendering of 2 dimensional images. These images may be used for visual display or for actual time viewing.
3 dimensional (3d) graphics utilize the same algorithms as many 2d computational vector graphics in a wire frame model and 2d raster graphics in the final rendering that is displayed. In 3d graphics software, the difference between the 2d and 3d model is complicated; 2d software in some occasions utilizes 3d techniques to obtain effects such as lighting, and often 3d graphics software technologies use 2d rendering techniques.
3d computer graphic files begin by creating a 3d model. Beside the rendered graphic, the model is managed within a graphical data file. Yet, there are some differences. 3d models have mathematical representations of object. A model is not considered a graphic until after lighting, color and backgrounds are added to offer a visual or rendered displayed.
Because of 3d printing, a 3d model no longer only exists in virtual space. Models can be shown visually as two-dimensional images through the process of 3d rendering, or used for physical testing such as finite element analysis and motion simulation.

3d Phases
Creating 3d computerized graphics occurs in three phases: 3d modeling which is the process of creating the shape of a part, the layout and the animation which defines the placement of parts within a scene, and 3d rendering which produces a photo-realistic image of an object.
