3D computer graphics (in contrast to
2D computer graphics) are graphics that utilize a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing. Despite these differences, 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 primarily 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 (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to
3D printing, 3D models are not confined to virtual space. 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.
