Abstract: A high-speed automatic image drawing apparatus divides a three-dimensional object to draw into primitives that can be drawn at a high speed, and draws an image of the object according to the primitives by gradually changing lightness and chromaticity. The image thus provided has a material-like impression. The apparatus comprises a primitive forming unit for dividing the three-dimensional object to draw into predetermined shapes and forming primitives according to the shapes, and a grading unit for drawing the object according to the primitives by gradually changing lightness and chromaticity. In response to a request of drawing a three-dimensional object, the primitive forming unit divides the object into predetermined shapes, and forms primitives for the shapes. Thereafter, the grading unit draws an image of the object according to the primitives by gradually changing lightness and chromaticity.

Abstract: A data conversion apparatus includes a plurality of computers connected to a network, a storage section, a retrieval section, data conversion processing sections, and a control section. The storage section stores plural sorts of information on the converter including a name of a computer equipped with a converter, a way of using the converter. A retrieval section retrieves information on the subject converter from the storage section according to a conversion request from a computer which requesting data conversion. The data conversion processing sections are connected to the respective computers and converts data into data of a format to be used with the converter on the basis of the result retrieved by the retrieval section. The control section controls the retrieval processing of the retrieval section and the conversion processing of the data conversion processing section to output converted data to the computer which requests data conversion.

Abstract: A multiprocess input system includes a first process execution part for processing input data, a second process execution part for processing the input data, and a third process execution part for distributing the input data to the first and second process execution part.
