METHOD FOR CONSTRUCTING THREE-DIMENSIONAL POLYHEDRON MODEL

摘要

ABSTRACT OF THE DISCLOSUREIn order to achieve an interpolation displayor a display object existing between two adjacent planesaccording to the triangulation when digital data on thetwo adjacent planes is given, the data items on the twoplanes are grouped into a plurality of connected compo-nents, respectively, and several connected componentson the first plane are projected onto the connectedcomponents on the second plane. Thereafter, a sequenceof points enclosing each one of the projected componentsare selected, and the selected point sequence is corre-sponded to a sequence of boundary points which encloseone of the connected components which contains the sub-component whose projected image onto the connectedcomponents on the second plane is equal to the projectedcomponent. Then, by using every corresponding pairs ofthe sequences, the triangular faces are generated.
