Abstract: A method and computer program are provided for implementing a method for cartoonish picturization by generation from three-dimensional object data. The placement of the three-dimensional object, the view point, and the position of an illumination light source are set. The direction in which the three-dimensional object exists is obtained as mask information, the colors indicating the object are obtained as color information, the distance between the object outer surfaces and the view point is object as distance information, and normal vectors of the outer surfaces are obtained as normal vector information.

Abstract: The present invention relates to obtaining vector data for a hand-drawn curve having coordinate values input from a pointing device and a thickness and/or density in accordance with pen pressure values. In order to reduce the amount of data input from the pointing device and obtain vector data therefor in real time, the coordinate data and pen pressure data are extracted independently of each other so as to reduce the amount of data stored in a memory and used for plotting or display.
