摘要： Systems and methods for automatically generating a three-dimensional model of an object based on an input set of images of the object that may only have partial or incomplete information about the object's shape are disclosed. The technique may assumes a template geometry, which represents a similar shape to the target object, and applies free-form deformation iteratively until the deformed shape matches a given set of partial views of the object. A non-linear numerical optimization technique is used to find the optimal deformation of the template geometry to achieve a good match. Also disclosed is an interactive design system that may be used to design an object whereby design modifications are applied interactively by a user to an existing design geometry to generate a new design geometry. The new design geometry is generated using extended free form deformation and optimization to deform the existing design of the object to match the new design.

摘要： In order to change the positions of a plurality of nodes that constitute a line or a surface, following steps are executed: storing in a storage device data of a normal for each node; changing the position of each node and storing the position information into the storage device by (1) defining a virtual elastic member connected to each node in a direction of the normal of each node, and (2) stretching or shrinking the elastic members in the direction of each normal so as to balance each elastic member; and repeating the storing step and the changing step until a predetermined condition has been satisfied. As a result, a smooth curve or smooth surface is generated.

摘要： Shadow images, which are formed on a light-receiving surface by occluding light emitted from a light source with at least one occluding surface, are drawn by the generating data representative of brightness discontinuity edges that partition the light-receiving surface into loop areas that are completely occluded by the occluding surface and loop areas that are partially or totally irradiated by the light source. An irradiation state is assigned to each loop area. The loop areas are then divided into meshes according to the irradiation state assigned to the loop area. Pixel data is generated for each element of the mesh and output for display on a display device.

摘要： The present invention provides a device capable of supporting drawing work while improving the continuity of the drawing work. According to a drawing support device 1, components corresponding to successive position trajectories of the tip of a pen 2 are displayed on a panel 3, and this enables drawing work with the feeling of hand drawing. Further, among the components displayed on the panel 3, the shape or the like of a “first component” to be a changing target is changed based on the shape or the like of a “reference component” selected from “second components” excluded from the selection of the changing target, so that the workload of adjustment of the shape or the like of the first component can be reduced. Although a second component targeted for a specification operation is specified as the reference component, since the pen 2 is used for the specification operation, continuity from the hand drawing of the components to the drawing work is not impaired. Further, the shape or the like of the first component is changed based on the shape or the like of the reference component, so that the workload of adjustment of the shape or the like of the first component can be reduced.

摘要： A computer-implemented method for extracting an approximated medial surface from a solid having a thin-wall geometry. The method includes generating a first mesh representative of the solid and including a plurality of mesh elements. The method further includes defining a mid-surface element for each of at least a portion of the volumetric mesh elements, segmenting a surface collectively formed by the mid-surface elements to form a plurality of surface regions, defining a boundary for each surface region, and fitting an approximate surface to each surface region and its corresponding boundary. The approximate surfaces collectively define the approximated medial surface.

摘要： Devices and methods for implementing computer-aided surgical procedures and more specifically devices and methods for implementing a computer-aided orthopedic surgery utilizing intra-operative feedback. A three-dimensional model of an area of a patient upon which a surgical procedure is to be performed is modeled using software techniques. The software model is used to generate a surgical plan, including placement of multifunctional markers, for performing the surgical procedure. After the markers are placed on the patient, an updated image of the patient is taken and used to calculate a final surgical plan for performing the remainder of the surgical procedure. The three-dimensional modeling, surgical planning, and surgery may all take place remote from each other. The various entities may communicate via an electronic communications network such as the Internet.
