3D Graphics is also known as 3D models. It involves the creation, display and manipulation of the objects in the three dimensions. 3D CAD and 3D graphics programs enable the objects to be produced on the X (Width)-Y (Height)-Z (Depth) scale.
The process of creating 3D computer graphics can be divided into three basic phases:
- 3D Modeling: It exemplifies the process of shaping the object.
- Layout and Animation: It provides the details regarding the motion and placement of objects.
- 3D Rendering: It gives out an image of the object.
3D graphics are produced by means of graphic art, digital computers and 3D software. Objects can be turn around and seen from all directions. Besides this, it can be scaled larger or smaller. They also flash lighting in the rendering phase.
Renovating information of 3D objects into a bit map is termed as rendering, and necessitates significant memory as well as processing power. Initially, 3-D graphics are obtained only on potent workstations, but now, things have been changed drastically, as 3D graphics accelerator are now commonly found in a personal computer. The graphics accelerator encloses memory and a specialized microprocessor on the way to take upon several 3D rendering operations.
