Abstract: A computer-implemented method queries a database that comprises modeled objects. Each modeled object represents a physical attribute of a respective real object. The database comprises for each modeled object, a respective simplicial complex. The method comprises providing a query that includes a signature criterion, and returning, as results of the query, respective modeled objects of the database. The respective modeled object is returned based on an extent to which the respective modeled object has a respective simplicial complex that respects the signature criterion. Such method system improves the field of searching modeled objects in a database.

Abstract: It is provided a computer-implemented method for designing a modeled volume. The method comprises providing a set of dexels that represents the modeled volume, each dexel comprising a set of at least one segment representing the intersection between a line and the modeled volume, wherein the set of dexels is partitioned into groups of neighboring dexels, and wherein a memory space depending on the maximum number of segments comprised in each of the dexels of the group is allocated to each group; providing a sculpting operation on the modeled volume; and updating the set of dexels in response to the sculpting operation. Such a method improves the design of a modeled volume represented by a set of dexels.
