Abstract: In order to circumvent the problems above, the present invention aims to expand the scope of the usage of the information included in three-dimensional shape data by acquiring the shape information included in the three-dimensional shape data automatically on a shape element basis and setting linkages across the acquired information. Linked processing can be performed across the corresponding shape information having different shape elements by adding a linkage identifier to the shape information when generating the shape information from the three-dimensional shape data. For example, when processing for a single shape information is carried out, other shape information can be edited by linkage.

Abstract: A method of generating a free-form surface model includes the steps of applying linear transformation to a lattice polygon model to generate vertices of a free-form surface model corresponding to respective vertices of the lattice polygon model, and generating control points of cubic Bezier curves that connect the vertices of the free-form surface model, and that correspond to respective edges of the lattice polygon model.

Abstract: The apparatus for coating a photosensitive material (M) with a processing liquid comprises an activator coating mechanism (43) for metering a constant amount of activator to apply the metered activator to the photosensitive surface of the photosensitive material fed by the pair of introduction rollers. The activator is supplied form a plurality of discharge holes (121) bored in a pipe (122) and is once received by a receiving portion (124). The activator is diffused horizontally and flows downwardly through a plurality of openings (123) bored at the bottom of the receiving portion onto a coating roller (125). The activator is diffused again at the contact between the coating roller and a diffusion film (126) and is coated to the photosensitive material by the coating roller.

Abstract: The current invention discloses the method and the system for designing a three-dimensional model object with an automatic updating feature which correctly and efficiently updates the model object in response to a modification command. In order to efficiently access a part of the object data associated with the modification command, a group of parts in the model object is referred by an index. Such groups include a face set, an edge sequence and a vertex, and these elements are associated to a given modification command by the index. The association between the modification command and the elements via the index provides an efficient yet flexible access to the relevant object data and substantially eliminates the unintended effects during the updating process.

Abstract: A 3-dimensional (3-D) Computer Aided Design (CAD) System generates a fillet surface which smoothly connects two surfaces to each other. This is accomplished by sliding a circle on a normal plane of a user-designated spine curve which is in contact with two surfaces. Then, the fillet surface is approximated by Gregory patches which are generated from trajectories of two tangent points between the circle and the two surfaces. The fillet surface thus expressed by the Gregory patches is easily and efficiently processed in computers such as those in 3D CAD systems. Because the fillet surface is generated along the spine curve, various fillet surfaces, including that generated by the conventional rolling-ball blending method, can be generated to satisfy various needs of designers of 3-D CAD Systems.

Abstract: A video signal defect compensation system is adapted to display an image on a video monitor without interruption. A video signal defect compensation device is adapted to reproduce a video signal, for a restricted time interval, from a memory medium on which a desired video program is recorded, and a video signal generator is adapted to continuously generate a predetermined video signal. Through a switching circuit, a video signal is selectively supplied from the video signal reproducing device or video signal generator to the video monitor. The switching circuit is controlled by a means for detecting whether or not the video signal reproducing device produces an output, and supplies a video signal to the video monitor while the video signal defect compensation device delivers the video signal, and supplies a video signal from the video signal generator to the video monitor while the video signal from the video signal reproducing device is interrupted.
