Ans : 3;-D Accelerator is no magic technology. It is simply an accelerator chip that has built-in ability to carry out the mathematics and the algorithms required for 3-D image generation and rendering. A 3-D imaging is simply an illusion, a projection of 3-D reality on a 2-D screen. These are generated by projection and perspective effects, . depth and lighting effects, transparency effects and techniques such as Ray-Tracing (Tracing the path of light rays emitting from a light source), Z-buffering (a buffer :toring the Z-axis positions) and Double-Buffering (two buffers instead of one).
