3D Computer graphics

Powerful computers and computing capability have enabled realism in computer generated imagery. The animated films made today are realistic to a fault. For instance, Shrek 3.0 has been wildly popular because of the life like characters which inhabit the movie.

3D animation basically consists of generating depth in 2D objects by various means. Lighting and shading is a powerful way to provide depth to objects and characters. At first the model of the object is created using a number of polygons. The density of polygons or the number of polygons for a given area defines the smoothness of an object. In applications like 3D video games where real time response is more important than faithful reproduction, the polygon density is obviously less. In applications such as a animated movie, realism of scenes take primary importance. The complexity of the objects requires a high polygon density.

Once the objects have been modeled, they have to be imparted motion or they have to be animated. Finally the animated objects which are essentially 3D in nature have to be converted to 2D. This process is called rendering. More the polygon density, more time it takes to render an object. It is often required to combine video and 3D images. This process is called compositing. Rendering process is one of the most important in generating a 3D image. A small bit of a movie lasting just a few seconds can take days to be rendered. Render farms and piping are phrases associated with 3D animation. Mental Ray is a renderer provided as a part of Softimage and Maya 3D packages. It is also gaining in popularity among other 3D developers. Renderman is a renderer used by Pixar and some large film production companies, for development of feature films.

A number of operations are involved in creating 3D animations. The three most popular software commercially available for 3D modeling , lighting and shading are Maya, 3ds Max and Softimage .Each of the software has its strength and tools to address various requirements of 3D design and development .

Maya was originally developed by Alias which has now merged with Autodesk. The developers of Maya claim its tools have superior capabilities for production of 3D animated movies.

3ds Max is also a Autodesk product, originally from Discreet. Due to its high availability and competitive cost, 3ds Max claims to be the most popular 3D software. It has an excellent game engine and is extensively used for video game development.

Softimage 3D software is a part of Avid. The developers of this software claim mixed pipeline management leading to more efficiency, less time for development and uniquely suited for game development.

3D computer generated imagery has caught the imagination of the public. US based movie moguls are spending hundreds of millions of dollars to create realistic feature films. These in turn are grossing many millions of sales. The 3D computer graphics industry is therefore growing in leaps and bounds. Features like natural hair, skin and human expressions are being refined and polished, to give life like appearance to animated objects.

Microsoft Windows

Microsoft Windows is an operating system for computers. Microsoft is the company and Windows group name for the various versions of operating systems that the company offers. An operating system is the platform for the computer. It makes it possible for the various software programs to function.

An operating system can be described like a power source. You have power coming into your home through the electrical supply. The electricity itself cannot bake a cake. In order to perform a task like baking a cake you will need several appliances that use the electricity. You will need a refrigerator to keep the milk, butter and eggs at a safe temperature until you are ready to use them. You will need a mixer to combine all of the ingredients. You will need an oven to provide the heat to bake the mixture. And it would be nice to have a dishwasher to help with cleanup. This is an overly simplified example, but it helps to demonstrate the difference between an operating system like Windows and software like Office.

An operating system can also be viewed in terms of security. Just like in a home or business, steps are taken to protect the people and property inside. Doors are locked. Alarms are set. Security guards are posted in key locations. Monitoring devices are used. For example, if the business is a bank, the cameras, the alarm panic buttons, the security guards really have nothing to do with the core business of banking. But in a society were safety is a concern, they are necessary for employees and customers to be willing to enter the building.

Another comparison from the business world is the role of a director of operations. This person is in charge of all the stuff that must take place in order for the company to do the work it does. This is the person who makes sure the building is safe and well-maintained. This is the person who makes sure the copiers work, the air-conditioning works, the phone system is up-to-date. This is the person who creates an environment where the function of the company can thrive.

Over the years that Microsoft has been in business, they have frequently launched new versions of the Windows operating system. Each version offers new, enhances features to make productivity and security better. The latest Windows operating system is Windows Vista. New computers that feature Microsoft components will be pre-loaded with Vista. For existing computers, IT professionals and individual owners will likely keep the operating system they already have. The systems will be compatible in most cases. When the company or person is ready to buy a new computer, they will make the change over to Windows Vista.

Windows Vista offers improved Internet experience with the ability to browse multiple pages at the same time from a single window. A Quick Tabs feature will allow you to see thumbnail views of webpages before you open them. Users can set controls to regulate when the computer can be used and what access the different users can have. This is a great way to control a computer used by the entire family.
