Abstract: In a synchronized contents information generating apparatus, a keyword extractor extracts a characteristic keyword from document information whose document is an electronic document, and an audio analyzer measures a keyword appearance distribution in the order in which the extracted each keyword appears based on audio/video information that is audio and video, recorded by a video camera unit, of how a meeting using the document goes on. A synchronized contents information generator generates synchronized contents information used to display the document information in synchronization with the audio/video information based on the keyword appearance distribution.

Abstract: As to an object-oriented programming, reuse of softwares is enhanced and running speed is improved. There are made up a data element list in which pointers to data storage areas of object A are arranged and a pointer element list in which pointers to pointer storage areas of object B are arranged. A combination of the data element list and the pointer element list makes it possible to directly refer to data of the object A from the object B.

Abstract: An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.

Abstract: A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.

Abstract: In one aspect of the present invention, a test is made as to whether or not polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays, with polygons which are not intersected being removed from the graphic data as unnecessary for the generation of CG data. In another aspect of the present invention, path passage points which pass through an animation path within a virtual world are interactively set, and if an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. In yet another aspect of the present invention, a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction, the position of the set path in the virtual world being calculated, and the position of the path in the direction of viewing being corrected to a position that is removed from an object by a prescribed distance.

Abstract: A three-dimensional graphic apparatus generates a three-dimensional image using computer graphics, in which the positional relationship between matters, such as furniture in a three-dimensional image, can be changed readily and accurately. A moving object indication unit indicates one of the matters in the three-dimensional image as an object matter. A search direction indication unit indicates a search direction of a base polygon constituting a base matter coming into contact with the object matter, from a notice point of a line of sight. A base polygon search unit selects, from among polygons located on a straight line extending from the notice point in the search direction, a polygon closest to the notice point as the base polygon. An object polygon selection unit selects an object polygon, which is a polygon to be brought into contact, from among polygons constituting the object matter.

A combination of the data element list and the pointer element list makes it possible to directly refer to data of the object A from the object B. Object-oriented programming is performed by displaying objects connected by wirings that represent the flow of data, control or messages from one object to a second object. A coupling of input and output terminal so that objects is shown by displaying a wiring between the terminals. A coupling structure is constructed in accordance with the wiring within an object hierarchy, so that instructions to rearrange, duplicate or replace objects may be permitted. The display is preferably divided into domains, for the respective display of the objects and the wiring.
