There are programs to automate nearly any task imaginable. Some disciplines have been quick to adopt these computer aided solutions while other have not. With each passing year, the capability of computers increases. Today\’s desktop computers are many more times more powerful then the computers which took humankind to the moon. Most people have more power at their fingertips than did entire universities of yesteryear. Programs have grown in like manner. Operating systems have become complex pieces of engineering marvel. All of these advances in hardware and software have made entire new industries possible. Computer graphics have risen to become a full-fledged industry. Perhaps the most impressive segment of this industry is that of 3D modelling software.

3D modelers as they are sometimes called, come with wide differences in capacity. Some are made to build simple models. Some can be used to design entire scenes. There are others of these programs that can be used to model people. A number of them can only produce static images, or struggle with anything beyond simple animation. The most robust modelers can be used to create and animate entire movies, building scene after scene.

Many people are aware of the film industry\’s extensive use of these amazing programs to create fantastic visual effects. What many people do not know, however, is that there is a greater demand for modelers in other disciplines. Some surveys indicate that the largest demand for artists is in the medical field. These folks create complex models of the human body and all of its intricate internal organs. These models allow medical scientists to research the effects of disease and allow them to work toward cures.

A high-growth area for jobs for these artists is the sciences. Chemists sometimes utilize the power of these models to create complex models of chemical chains and compounds. In addition, many earth scientists are turning to this technology in an effort to better study the earth. Geo-chemists can make three dimensional models of many of the earths compounds. These models can be used to study how compounds interact and combine with each other. Geophysicists can study the interaction of various forces, such as gravity and inertia. Geologists can build models of very complex formations, such as tectonic plates to further study seismic activity.

These complex modelers can be used to create interactive maps of the earth. A really great feature of one of these models is that the surface can be removed to show what is going on underneath the ground. Volcanic formation theory can be tested.

3D modelers uses a variety of tools and techniques to achieve the finished image. One technique is to start with a basic shape or primitive. The surface of this shape is subdivided into lines and points. Each point can be moved about, reshaping the primitive. A second technique involves creating a series of lines which form the outside boundaries of the model. These frames are then manipulated until a final shape is reached. A final method for creating solid models is through the use of mathematical formulas called NURBS. Smoke, dust, and other particles are created through additional tools, referred to as particle systems. Creating water usually takes some combination of several methods.

Upon completion, the model is ready to be rendered. Some kind of light must be provided. The image must be constructed with some kind of camera angle.

The ability to create complex animated models has lead to an increased use of 3D modelling software. This has in turn led to an increased demand for skilled artisans to create usable models. A wealth of information is available on the world wide web of anyone interested in learning the necessary skills.
