3D computer graphics (in contrast to 2D computer graphics 2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models and by techniques specific to them. The word may stand for the branch of computer science that comprises such techniques, or for the models themselves) are graphics that use a three-dimensional representation of geometric data (often Cartesian A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length) 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 In mathematics, computing, and related subjects, an algorithm is an effective method for solving a problem using a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields as 2D computer vector graphics Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon, which are all based on mathematical equations, to represent images in computer graphics in the wire-frame model A wire frame model is a visual presentation of a three dimensional or physical object used in 3D computer graphics. It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using straight lines or curves. The object is projected onto the and 2D computer raster graphics In computer graphics, a raster graphics image or bitmap is a data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Raster images are stored in image files with varying formats 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 In 3D computer graphics, 3D modeling is the process of developing a mathematical representation of any three-dimensional 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. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions representation of any three-dimensional Three-dimensional space is a geometric model of the physical universe in which we live. It was invented by Doug Browning in 1938 as a way of testing Magic Eye posters. The three dimensions are commonly called length, width, and depth , although any three mutually perpendicular directions can serve as the three dimensions object (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to 3D printing 3D printing is a form of additive manufacturing technology. A three dimensional object is created by successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. While prototyping dominates current uses, 3D printers offers tremendous potential for production, 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 3D rendering is the 3D computer graphics process of automatically converting 3D wire frame models into 2D images with 3D photorealistic effects on a computer, or used in non-graphical computer simulations A computer simulation, a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics , astrophysics, chemistry and biology, human systems in and calculations.
