Abstract: A simulation apparatus which simulates a position of each of a plurality of objects, which move in a virtual space together with time, at each of a plural calculation time is disclosed. The apparatus includes: an object connection block for applying, to each object of each three or more objects contacting with each other at each of the plural calculation time points, a pointer value indicative of a contact destination object with which the object is in contact determining one of the three or more objects as a terminal end to connect the objects; and a pointer value updating block for repeating a pointer value updating process, by which the pointer value of each object is updated to the pointer value of the contact destination object indicated by the pointer value until the pointer values of all of the objects come to indicate the object of the terminal end.

Abstract: Disclosed herein is a simulation apparatus which simulates a position of each of plural objects, which move in a virtual space together with time, at each of plural time points of calculation. The apparatus includes: an object pair information acquisition unit acquiring plural pieces of information of object pairs each including, as components thereof, two objects which contact with each other at each of the plural time points of calculation; an allocation unit allocating, at each of the plural time points of calculation, each of the plural object pairs to one of plural groups such that two or more object pairs which include a common object do not belong to the same group; and a calculation unit calculating, at each of the plural time points of calculation, an influence of contact of two objects included in each of the plural object pairs upon positions of the two objects.

Abstract: An object placement managing unit changes at least one of a position and a direction of a virtual object based on a value of a parameter associated with a physical quantity that is an attribute of the virtual object. The object placement managing unit determines a first change, which corresponds to a user's operation, in a first physical quantity of the virtual object. The object placement managing unit determines a second change in a second physical quantity. The second change corresponds to and is different from the first change. The object placement managing unit changes a value of a parameter based on the first change and the second change. The object placement managing unit changes, after the value of the parameter is changed, at least one of the position and the direction of the virtual object based on the changed value of the parameter.

Abstract: Provided is an image generating device for generating an image of an object including a plurality of elements connected to one another. The image generating device includes: a calculating section for iteratively calculating a motion of each element of the plurality of elements based on a physical constraint condition of the each element with respect to another connected element; a parent-child information acquiring section for acquiring parent-child information corresponding to a connection between the each element and the another element based on information indicating an element having a predetermined relationship with another object; a correcting section for correcting a position of a child element with respect to a parent element based on the parent-child information and the motion of the each element; and an image generating section for generating information on the image of the object based on the corrected position of the each element.

Abstract: An information processing device includes target object information obtaining unit configured to obtain target object information indicating a position and an area of a target object in a virtual space, surface information obtaining unit configured to obtain surface information indicating a position and an area of a thickness area that is defined by a surface in the virtual space and a predetermined thickness imparted to the surface, and collision determining unit configured to carry out collision determination, based on the target object information and the surface information, so as to determine whether the target object has collided against the surface.
