The use of graphics modeling has exploded with the growth of computer power.
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.
