Abstract

The invention is applicable to the technical field of computer visualization processing, and provides a three-dimensional data clipping method which comprises the following steps of: drawing the three-dimensional data in projection transformation; selecting a visualization area to be processed; constructing the curved line and curved surface of the clipping area; and modifying the three-dimensional data according to the constructed cured surface, and re-drawing the modified three-dimensional data. Preferably, the three-dimensional data can be subjected to volume rendering or surface rendering in parallel projection, and modification on the three-dimensional data is realized by virtue of Boolean calculation. The invention also provides a three-dimensional data clipping system for realizing the method. Therefore, according to the invention, the three-dimensional data is drawn so as to ensure that users can observe conveniently, thereby realizing the purpose of carrying out interactive modification on the three-dimensional data in visualized situation.
