Mathematical models are very important for solving many problems. Graphics are often very useful to represent physical models and enhance problem solving. Computer graphics have many applications such as displaying information such as in CT scans, the designing and the checking of safety of cars, and interaction through flight simulator. Geometric representation of 3 dimensional objects are composed of lines in 3-space. Such may be represented as two points on the same line or one point and one directional vector.
Geometric manipulation is done by the use of vector math and matrix algebra.
Vector and matrix equations can be manipulated by translations or a series of translations such as rotations and shears. Graphics are further rendered with shading and lighting effects. To view graphical information, projections and clippings must be calculated. Problem Justification Especially with the contunued explosion of computing power, the use of computer graphics is important because people must deal with the physical world which is best represented with graphics. A computer mathematically manipulates the graphical representation, calculates, may display results of a graphics model and provide a interaction with that model.
