ABSTRACT:
The numbers of nodes forming each polygon and the spatial coordinates of these nodes are stored as polygon data in a data storage unit. On the basis of this stored data, a model drawing unit expresses a model. To deform the model by using an operating tool expressed by polygons, a node formation circuit forms new nodes near a contact node to repaste polygons, thereby expressing an incised portion.
