Physics of Computer Graphics Essay -- physics computers graphic CG

In the field of computer graphics there are usually quad general applications that one thinks of1. Display of Information2. Design3. Simulation and Animation4. User interfaces(Angel, 2)With regards to applied physics applications, the area of computer graphics most focused on is simulation and animation. This is found in several different fields such as aerospace, manufacturing, wireless communication, resource recovery, film-making, computer games, and virtual reality. Moreover, physics- ground modeling is now in general accepted as a third principal mode of scientific investigation, along with theory and experiment. (Mason)The goal is to usually create 3-dimensional objects and have them move and interact on the screen using data based off of physics equations(i.e kinematic equations, energy and momentum, etc.) However often times programmers and animators dont necessarily want to deal with having to code in every equation every time they want to have an object interact w ith something new. This brought forth the development of physics engines. As processors have become more powerful, animators began to reach and represent there animations using more realistic methods. In todays latest animated blockbusters like Shrek 2, to some of todays hottest video games like Halo 2.In lodge to achieve these realistic effects computer animators often use high-powered physics engines to simulate real-life physics inside a computer-simulated world. An example of such a computer graphics engine is Impact, which includes six physics engines Force Field, Law of Gravity, Gravity (used to target a particular object), Springy Thingy, Thruster, and Torque Motion.(Mortier)These engines enable animators to ... ...it would ascertain to render would freeze even some of the fastest machines out there. So what happens is we fudge the data and have each object appear brighter or darker based off of a simpler equation that gives the appearance that lighting does exist.Bi bliographyAngel, Edward.
