Approximation method of shape data, information processing apparatus and medium |
February 10, 2004 |
| An shape data approximation method for reducing the amount of data with an adjacency relationship between a plurality of components maintained. The shape data is read, an adjacent region of the shape data is designated, a virtual surface and a virtual edge are created in the designated a |

Image data approximation considering normal vectors |
December 4, 2001 |
| Distortion of normal vectors when approximating shape data with normal vectors is restrained. At step ST1, original polygon date is input. At step ST2, each edge is evaluated for performing removal of an edge. At step ST3, the evaluation values are sorted by magnitude and the edge ha |

Method for approximating shape data, drawing apparatus and information recording medium |
July 18, 2000 |
| A method and apparatus for approximating shape data in which the degree of fineness of a desired portion is set so as to differ from that of other portions for hierarchical approximation by a facilitated designating operation. Polygon data of an original are entered and the partial degre |

Computer animation generator creating hierarchies of models for rapid display |
June 30, 1998 |
| A drawing method of computer graphics in which an approximation of a model is executed in consideration of a target point of the observer, a position of model, a size of model on a picture plane, and a moving speed of model are considered and, further, a feeling of physical disorder that |
