Abstract: An information processing apparatus inputs shape data indicating shapes and positional relationships of a plurality of objects; based on the shape data, in a space formed by a plurality of blocks each having a predetermined size, generates block data in which a corresponding attribute of an object or a space is allocated to each of the plurality of blocks; determines a part of blocks adjacent to a block having the attribute of the object in the block data as a block used for detection processing of a difference of contacted states of the objects between the shape data and the block data; and performs the detection processing by using the determined block as being used for the detection processing among the blocks adjacent to the block having the attribute of the object.

Abstract: A geometry simplification apparatus includes a determination unit configured to determine whether another component is in contact with a simplification target place, a simplification unit configured to simplify the geometry of the simplification target place, a determination unit configured to determine whether another component is in contact with the simplification target place of which the geometry is simplified, a comparison unit configured to compare contact relationship between another component and the simplification target place before and after the simplification of the geometry of the simplification target place, and a correction unit configured to correct the geometry of the component in which the geometry of the simplification target place is simplified to a geometry which does not interfere with another component according to comparison results by the contact relationship comparison unit.

Abstract: The present invention relates to a geometry simplification apparatus including a simplification target feature extractor and a geometry simplification processor. The simplification target feature extractor extracts a second feature, similar to a first feature in geometry from a part for which geometry simplification is manually performed, based on information about the first feature. The geometry simplification processor simplifies the second feature extracted by the simplification target feature extractor based on information about a geometry simplification method performed to the first feature.
