摘要： PURPOSE:To easily deform and correct the shape of a produced wire frame and to efficiently produce the shape of the wire frame. CONSTITUTION:A primitive is set in a three-dimensional space as the gage data, and the edge line of the primitive is converted into a free curve of a wire frame by a data converting means 13. The corresponding relation between the edge line and the free curve is stored in a corresponding relation storage means 14. A shape changing means 15 changes the wire frame by moving the free curve through a pass point or by expanding, moving and revolving the gage. The primitive that is first supplied as a rough shape is used as a gage and then converted into a wire frame. Then the wire frame is deformed into a detailed shape. In such a procedure, the input of a shape is facilitated and also the corresponding relation is stored between the gage and the wire frame. Thus the wire frame is changed when the shape of the corresponding gage is changed.

摘要： PURPOSE:To easily, speedily and automatically generate the curved surface of an arbitrary shape so as to display it on a screen. CONSTITUTION:A surface spanned over a closed curve is expressed as a film having a physical character. It is expressed as the surface where an elastic film is spanned over a closed curve, for example. The shape of the elastic film is changed by permitting an operator to designate the film pressure and the normal line-direction of the elastic film on the closed curve so as to express the curved surface.

摘要： PURPOSE:To reduce the problem of dynamic definition at a work stage by storing a design data inputting output processing information showing the output form of the design data at one of the plural stages, and outputting the design data based on the output processing information corresponding to the work stage. CONSTITUTION:While executing design work at a work stage 101, a picture 110 of a display device as an output means is defined. As the result, a display processing peculiar for the work stage 101 and an edition processing are provided as the attributes. Since the new work stage can be started even while working/editing the design data by providing a means to define the new work stage through a data input device linked to the picture to execute work/edition, it is possible to deal with the change of the design work.

摘要： PURPOSE:To design a three-dimensional object by means of the support of a computer which is excellently reflected to the sense of a designer by using a form input/output device which displays a three-dimensional model generated in the computer in a concrete three-dimensional form and inputs the three- dimensional form in the computer, and a graphic processor having the computer. CONSTITUTION:A graphic processing means 310 displays the model in the computer in a graphic display device 100 through a connection 11, and transfers information on the graphic display device 100 to a stereo form input output device 200 through a connection 12. The stereoscopic form input/output device 200 sets the pin position of a pin matrix by an on-line pin position setting part. An operator 26 visually recognizes the graphic display device 100, and instructs the operation of the processing and the edition of a computer model, or rotation, shift, enlargement, reduction, disconnection or the like with respect to the model by a command 14 or, the pin position of the pin matrix in the stereoscopic form input/output device 200 is corrected based on commands 31 and 33 to attain a processing. Thus, the deseired stereoscopic film is recognized and generated.

摘要： PURPOSE:To automatically execute the formation of density or the addition of a boundary condition by using a shape and its attribute information as deciding information to form data constituted of nodes, elements and their attribute information. CONSTITUTION:Two-dimensional or three-dimensional gratings including a shape are formed in a three-dimensional space by using a space expressing means and specifying the information of the objective shape and the request accuracy of element division. A density dividing means 2 decides whether respective gratings expressing the fine spaces of the space divide the fine grating spaces of themselves in response to the graphic of the shape or attribute information or not to execute density processing. Then, a density division adjusting/ correcting means 3 adjusts the size of the gratings and determines the connecting relation of nodes and elements. Finally, an element shape correcting means 4 arranges the configuration of the elements. A process information processing means 5 smoothly executes density forming processing by tracing tree structure and calls the tree structure corresponding to data.

摘要： PURPOSE:To take out easily the arbitrary area of a graphic by inputting previously graphic geometrical and phasal conditions to an information processor, giving end points of the graphic as indication information, extracting sequentially a line segment which includes new end points and satisfies both conditions and updating it. CONSTITUTION:With the aid of the indication of the line segment A, which is inputted through a terminal, and the number of phasal dimensions 2, a host computer retrieves line segments B, D and C, extracts and area ABCD and registers it in a data base. Then the area ABCD and the line segment AB are taken for a reference area and a new reference graphic, respectively, and a new area is retrieved. An area BCDA is the same area as the area ABCD, and accordingly is not recognized as a new area. With the line segment C as a new reference graphic, an area is retrieved, and the areas CDAB and CEFG are extracted. Among two graphics, only the area CEFG is recognized as a new area, and registered. When the retrieval is terminated with all segments comprising the reference area ABCD as a reference graphic, the host computer decides the area CEFG to be a new reference graphic, and keeps the retrieval of the area. Thus a necessary area can be quickly taken out.
