Abstract

A simulator having a video generating function of creating a video of the behavior of an object to be analyzed in real time and a simulating method are disclosed. The behavior of an object to be analyzed is divided into partial spaces. Each partial space is subjected to simulation calculation by nodes (431 to 438) and visualized into a partial video by applying an MP method. The partial videos are sent to a composer (44) of a pipeline structure and mixed taking the concealment/exhibition relationship into consideration using the viewpoint determined by the BSP method as a reference. The mixed video is subject to distortion correction by using a texture mapping function by a server (40) and displayed on a display unit (41).

Dependent claims

A simulation system having an image generating function, comprising:

a plurality of subspace simulation means for simulating the behavior of an object of analysis in every prescribed time interval for a respective one of a plurality of subspaces created by dividing a three-dimensional space in which a mathematical model for said object of analysis is constructed;
a plurality of subspace image generating means for generating subspace images within said prescribed time interval, said subspace images representing the results of the simulations performed for said respective subspaces by corresponding one of said plurality of subspace simulation means;
