The term "3-D design" is a widely used abbreviation for three-dimensional design, incorporated commonly in design procedures associated with computers and other electronic drawing systems. In 3-D design techniques, a designer uses all three axes (x, y and z) to interpret and develop a realistic figure of the desired object.
Three-dimensional designing technique can be regarded as an electronic attempt to achieve the real-world perception model of human vision, since the real-world environment is strictly perceived in three dimensions by human beings. In this regard, a 3-D designer is capable of presenting any naturally occurring or human-made object in its realistic format, which is the most significant feature of 3-D design technique today.
Almost all 3-D design techniques incorporate four fundamental processes while interpreting an object electronically in its three dimensions: modeling, layout designing, animation and rendering. Modeling in 3-D designs is referred to the interpretation and development of basic object shape, while layout designing deals with the placement of an object within a suitable background. Similarly, the process of animation deals with any movement or motion associated with the object, and rendering defines angling and positioning of the light source within the design.
Three-dimensional designs are usually developed on electronic interfaces, such as computers or other image/video processing machines, using some specially developed common software applications like Photoshop, AutoCAD, Flash, 3-D Studio Max and Maya. Upon development, these designs can be viewed electronically or in the form of printed 3-D objects.
