• Anti-aliasing is inherent in Computer Graphics and cannot be totally eliminated but definitely reduced.

  • Aliasing occurs when high frequencies are present in the image and the image is sampled below the Nyquist rate.

  • Aliasing produces effects such as jagged edges, improperly rendering and disintegrated textures in the image.

  • Prefiltering and Postfiltering are the two basic methods for antialiasing.

  • In addition to the aliasing problems discussed, there are other problems in Ray Tracing and Texture mapping too.

  • Aliasing can also occur in the time and the color domain.
