For improving the compression efficiency of 3D model processing, easier discovering of repetitive patterns is required. The invention enables simplified and improved compression of 3D models by using a pattern-instance record table, which provides the pattern-instance relationship for all instances of repetitive patterns within a 3D object. A 3D mesh model comprises data of a first reference 3D mesh model, an electronic pattern-instance record table comprising first and second instance data, wherein the first instance data points to the first reference 3D mesh model and the second instance data points to the first or a further reference 3D mesh model, and an instance record for third instance data of at least one secondary 3D mesh model instance, wherein the third instance data comprise said first and second instance data or references to said first and second instance data.

The invention is related to a method and a device for encoding of a bit sequence. Said method comprises generating, for each run of Ones comprised in the bit sequence, a unary representation of length of the respective run of Ones, generating a first sequence by concatenating the generated unary representations of lengths of runs of Ones, generating, for each run of Zeroes comprised in the bit sequence, a unary representation of the length of the respective run of Zeroes, generating a second sequence by concatenating the generated unary representations of lengths of runs of Zeroes, and bit plane encoding the generated first and second sequence of unary representations. In most cases, overall entropy of bit planes of unary representations of run lengths is smaller than entropy of the bit sequence. Thus, more compact encoding can be achieved.

A fixation structure for fixing a superconducting cable including a cable core and a thermal insulation tube. The fixation structure includes a fixation box connected to the thermal insulation tube, including a hollow thermal insulation structure, and through which the cable core is passed, a fixation body for fixing the cable core on the inner wall of the fixation box, and a diameter-expanded reinforcement layer that is an electrical insulation layer that has a diameter decreasing toward both ends and is formed on the cable core. A refrigerant flows through the inside of the inner wall of the fixation box. The cable core is fixed on the inner wall with the fixation body through the diameter-expanded reinforcement layer. The structure implements a simple and low-cost fixation structure appropriate for an electric field design.

摘要:
3D models often have a large number of small to medium sized connected components, with small numbers of large triangles, often with arbitrary connectivity. The efficiency of compact representation of large multi-component 3D models can be improved by detecting and representing similarities between components thereof, even if the components are not exactly equal. The invention uses displacement maps for encoding two or more different but similar geometry patterns differentially, based on clustering and a cluster representative surface. A method for encoding a plurality of geometry patterns comprises detecting and encoding identical copies of geometrical patterns, detecting and clustering similar geometry patterns, and detecting partial similarity. The detecting partial similarity comprises generating a cluster representative surface, generating for at least one clustered geometry pattern a displacement map, and encoding the common surface and the displacement maps.
