Page "Computer animation" Paragraph 26

Computer animation uses different techniques to produce animations.

Most frequently, sophisticated mathematics is used to manipulate complex three dimensional polygons, apply “ textures ”, lighting and other effects to the polygons and finally rendering the complete image.

A sophisticated graphical user interface may be used to create the animation and arrange its choreography.

Another technique called constructive solid geometry defines objects by conducting boolean operations on regular shapes, and has the advantage that animations may be accurately produced at any resolution.
