Essay on Physics of Computer Graphics

856 Words 4 Pages
In the field of computer graphics there are usually four general applications that one thinks of:
1. Display of Information
2. Design
3. Simulation and Animation
4. User interfaces
(Angel, 2)

With regards to applied physic's 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-based modeling is now generally 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

With a simple click of the button they can then apply the appropriate algorithms to there animations.

However, with computer graphics mainly being driven by the entertainment industry often times animator's cheat with physic equations to create something that is more visually appealing to the eye.

When creating images that will be viewed by the masses there are often times that computer animators need to cheat physics and create there own rules and boundaries. Whether it is because a certain calculation would take too long to computer during run-time to just trying to create something that will WOW the audience are considerations that every animator must make.

To begin with let's first look at the area's in which computer animator's tries to mimic physics as closely as possible. First most computer animations go by the particle model (Jewett, 24) when dealing with objects. Often times they will start out with nothing more then a block or come other basic figure, build the physics equations and data around that model, and then later build up the model to make it look what they want to look like. This allows them to use the real physics equation as closely as possible.

One of the problems with fully using equations from physics is the computational time it requires to render each scene accurately. However, in the case of research it is more important to create the scene
