3D computer graphics or graphic arts use three-dimensional representations of figures instead of older 2D models. They have several advantages over 2D representations, not least of which is that the representation provider uses much more accurate and realistic, so the results can be much more accurate and realistic, too. Although 2D representations were certainly a good start, 3D models allow a 3D object, for example, to be scanned into a computer, after which they can be manipulated to produce different effects.
How it works
With 3D graphic arts, objects are laid out within the scene and then rendered. The location and size of the objects and relations of the rest of the scene, as well as its movement and deformation over time, are also taken into consideration.
3D rendering is done to convert a model into an image, which can then be manipulated to determine various effects.
Uses for 3D modeling or 3D graphics
One of the most effective uses for 3D modeling or 3D graphics is in mechanical product design. With 3D graphics, prototypes can be developed much more rapidly; in addition, these prototypes are clean and there’s a smooth transition to the final product, which lowers costs and manufacture. Many companies require prototypes to be produced quickly, and 3D graphic art programs can fill this need, for the lowest cost and most expedient processes possible.
3D graphic cards also be used with human modeling, for artists who want to manipulate human figures within scenery.
Many people can use 3D graphic arts programs during the manufacturing process
3D model design services can be used by many different people, including design technicians and engineers. This allows them to have working models of the product while still in development so that product development and ultimate manufacturer is much more efficient. 3D modeling allows for much more efficient prototyping than traditional methods to do, in that they are much more efficient and much less time-consuming than traditional methods. Product development was rife with delays when traditional methods were used, but this drawback has largely been mitigated with the advent of 3D modeling through 3D graphics programs.
Some advantages to using 3D graphic arts programs
* Because manufacturing drawings can be visualized in 3D, this gives developers a significant advantage over 2D renderings or even simple drawings.
* When one feature is altered, other information is automatically highlighted that depends on that feature, called “bidirectional parametric association.”
* Assembly designs are much simpler, showing the relation between related parts and full assemblies as applicable.
* 3D sectional views allow for a closer look at the “product” in its modeling stage.
* Clearance, interference and kinematics can all be checked in assemblies in 3D format without the hassle of having a physical prototype to change, redevelop, reconstruct, etcetera.
3D graphic arts programs to try
You can find 3D graphic arts programs online; Adobe makes a popular 3D graphics program, and some of these are also available as “freeware” with limited functionality if you want to try before you buy. Other possible choices include DAZ | Studio, completely free 3D artwork, Google SketchUp (also free), and Autodesk 3D Studio MAX (Windows).
