A shape data generation method includes: identifying, from among a plural vertices of a first shape to be transformed, one or plural first vertices satisfying a predetermined condition including a condition that a normal line of a vertex to be processed crosses with a second shape that is a shape of a transformation target, which is identified from image data; transforming the first shape so as to move each of the one or plural identified first vertices a predetermined distance toward a corresponding normal direction of the identified first vertex; and storing data concerning the plural vertices of the transformed first shape after the identifying and the transforming are executed the predetermined number of times.

This method includes: generating data of a mask surface with respect to visualization data arranged in a virtual three-dimensional space, for calculation values at respective calculation points; identifying, from a first data storage storing, as time-series data, positions of the calculation points and calculation values at the calculation points, a first point whose position is closest to a predetermined point on the mask surface; reading out, from the first data storage, a position of the identified first point in each time; arranging the mask surface in each time based on a direction of a user's sight line and the read position in each time so as to make the mask surface perpendicular to the direction of the user's sight line and have the predetermined point on the mask surface arranged at the read position; and drawing polygon data of the visualization data and the mask surface in time series.

A method includes: obtaining designated 3D template for a designated part in a heart; generating 3D annulus data representing an annulus of a heart valve identified as a reference of transformation, from a cross-section image in a plane passing through an axis within the annulus of the identified heart valve in 3D volume data generated from tomographic images; identifying a first point on the annulus of the identified heart valve in the designated 3D template and a second point on the annulus represented by the 3D annulus data; arranging n starting points from the first point on the annulus of the identified heart valve in the designated 3D template and n target points from the second point on the annulus represented by the 3D annulus data; and calculating movement destination coordinates of vertices of polygons relating to the designated 3D template to transform the designated 3D template.

A fluid structure interaction simulation method includes a graph information forming process to form graph information of nodes obtained by discretising a computing region for each of a fluid and a structure that are represented by meshes, and a main time development loop process to simulate a physical phenomenon. The loop process includes arranging IMEs (Interaction Mediating Elements) that move with a displacement of the structure, on a boundary of the structure, defining, within the IME, correcting functions of a pressure and a velocity of the fluid that interact with the pressure and the velocity of the fluid and the displacement of the structure, and executing a simulation based on the correcting functions, in a state in which the meshes of the fluid are mismatched to the meshes of the structure.

A vortex extraction apparatus includes: a first numerical data calculation section calculating, for each vertex of each of voxels into which the inside of a fluid space is split, first numerical data indicating whether the vertex is located inside or outside a vortex region in a fluid; and a text data creation section determining the size of the vortex region around a center line of the vortex based on the first numerical data, and creating text data indicating the center line and the size. The apparatus further includes a polygon count reduction processing section counting the number of polygons defining a surface of the vortex region and each including an isosurface of the first numerical data, and integrating the voxels with new voxels into which the fluid space is roughly split until the number of polygons is not more than a set value, to decimate the first numerical data.
摘要:
An information center transmits information as the object of sales to each information vending machine in advance through a communication line and stores it in the information storage portion of each information vending machine. Each information vending machine stores correspondence list which specifies the correspondence of each information vending machine with the information as the object of sales which is stored therein. When the information vending machine operated does not store the information requested by a purchaser in the information storage portion thereof, the information vending machine refers to the correspondence list, finds other information vending machine which stores the requested information, receives the information from the other information vending machine through the communication line and copies the information on a recording medium so as to sell the information. It is thus possible to increase the number of kinds of information sold by each information vending machines without increasing the capacity of the storage unit thereof.

An information distribution system for distributing information, containing: a first station for transmitting a first signal carrying information to at least one second station; the at least one second station for receiving the first signal, and transmitting a second signal carrying the information to an area around a place at which the second station is located; and at least one terminal for receiving the second signal, and displaying the information. The second signal is a wireless signal. The at least one terminal contains, a wireless receiver unit for receiving the second signal, a storage unit for storing the information, a display unit for displaying the information stored in the storage unit, a display control unit for controlling the storage unit and the display unit in accordance with a display command, and a unit for inputting the display command for commanding the display control unit how the information stored in the storage unit is to be displayed.
摘要:
A method of protecting data in an IC memory card (11) having a ROM area (11a) and a RAM area (11b) and used as an external storage medium of a computer system includes storing key data for preventing copying in the ROM area and using the key data to prevent the copying of data stored in the RAM area. For example, when a file is written, second key data (k1, k2, . . . ), which is inserted into the headers (H1, H2, . . . ) of files (11c-1, 11c-2 . . . ), is decided in such a manner that a fixed correlation will exist with respect to first key data (K1, K2, . . . ) stored in the ROM area (11a), and the second key data is written in the RAM area (11b). When a file is read out of the IC memory card, a check is performed to determine whether the fixed correlation holds between the first key data that has been written in the ROM area and the second key data that has been inserting into the header of the file. The file is read out only if the fixed correlation holds.
