Abstract: In order to visually display a spatial distribution of a multi-value function represented by nine components of a two-order, three-dimensional tensor, a distribution function of an anisotropic fine face distribution is set to have a form of a second-order curved surface of an anisotropic ellipsoid associated with discrete sampling points, the intensity of the scattering light is calculated from a contribution of a bisector-direction vector between a light-source-directed vector and a line of sight vector (in a reflection light intensity calculating part to simulate the light scattering. With respect to each calculation point having a tensor, the intensity of the scattering light is integrated according to a rendering light beam equation with a light transmittance weighted (in a light beam integration part).

Abstract: A method for providing information service is disclosed that enables resource procurement in a compatible manner among information processing service resource providers which are hard to uniformly manage because of the variation of quality and performance of resources provided, develops a market of freely trading adequately-performing resources based on performance simulation, and operates the management system of resource trading in such market.

Abstract: In a method of representing and rendering three-dimensional data on a computer display using vectors, a three-dimensional surface to be displayed is divided into a large number of unit surfaces. A coordinate position of each unit area is displayed by vector information constituted by a normal vector which has a vector direction indicating a normal direction of each unit surface and a vector length indicating an absolute value of a surface area of each unit surface. The normal vectors are combined to obtain data for representing the three-dimensional surface.

Abstract: Each of a plurality of simulation programs is linked with a data conversion library and is executed as a simulation process. A data conversion process is executed in correspondence with each simulation process. In exchanging data resulted from simulation by the simulation process of one of the simulation programs with simulation processes of the other simulation programs, the data conversion process provided for a sending simulation process determines a receiving simulation process to which the data is to be sent, and sends the data to the data conversion process corresponding to the receiving simulation process. The data conversion process for the receiving simulation process performs data conversion for absorbing difference between the base of the sending simulation process and the base of the receiving simulation process, and transfers the data after the conversion to the receiving simulation process.

Abstract: A method for compressing and decompressing multidimensional data based on approximating the data space by a smoothed particle cluster representation. The smoothed particle cluster representation is obtained by simulation for relaxation motion of a simulated particle corresponding to a sampling point to obtain a statistical average arrangement of the simulated particles on the basis of an equation of motion based on a potential theory given by an assumption that the simulated particles are moved upon receiving a repulsive force between the simulated particles, a velocity resistance, and a force proportional to a functional potential gradient having a large negative value in a region having a large original data value. The coordinates and an interval of the sampling points are obtained in accordance with an arrangement state of the simulated particles. The volume associated with each sampling point for obtaining the associated data value is the volume of the simulated particle.

Abstract: In a method of transferring and displaying 3-D shape data in a system including a transmission unit for transmitting 3-D shape data constituted by a plurality of elements representing shapes, and a reception display unit for receiving the 3-D shape data and displaying the 3-D shape data as an image, the transmission unit is caused to progressively transmit the 3-D data in units of elements. The reception display unit is caused to receive elements transmitted from the transmission unit and to progressively display the elements in an reception order.
