Creating Special Visual Effects with Moiré Patterns in Stereoscopic 3D and 4D Computed Tomographic Art

Moiré pattern refers to an interference pattern that is observed when two sets of grid lines overlay one another. With special 3D rendering technique such as the "Rainbow Technique" for tomographic art generated from computed tomography (CT), the Moiré pattern can be utilized for its aesthetic effect, particularly in stereoscopic motion images to create a special visual effect. The use of the Moire pattern is featured in my piece Deep Within in the new media art exhibition "Digit@logue" curated by Ellen Pau held in Hong Kong Museum of Art in 2008.
