An object of the invention is to efficiently create a 3D model of a plant with attributes from a 3D model of a plant with no attributes. In order to solve the above problems, in the invention, a connection information conversion part 5 converts a connection relationship of parts extracted from a 3D model with no attributes 2 into connection information of a system diagram, an extraction information comparing part 6 compares the connection information with the connection relationship extracted from an attribute system diagram to create an conversion correspondence DB 7, and a 3D model with attributes 9 is created based on the conversion correspondence DB from the 3D model with no attributes 2.

Described herein are a system and methods for efficiently using depth and image information for a space to generate a 3D representation of that space. In some embodiments, an indication of one or more points is received with respect to image information, which is then mapped to corresponding points within depth information. A boundary may then be calculated to be associated with each of the points based on the depth information at, and surrounding, each point. Each of the boundaries are extended outward until junctions are identified as bounding the boundaries in a direction. The system may determine whether the process is complete or not based on whether any of the calculated boundaries are currently unlimited in extent in any direction. Once the system determines that each of the boundaries is limited in extent, a 3D representation of the space may be generated based on the identified junctions and/or boundaries.

The present invention discloses a bullet with a negative Poisson's ratio effect and a method of designing thereof. The bullet includes a cylindrical section of the bullet having a negative Poisson's ratio design, and a conical tail of the bullet and a tip of the bullet each with a matching design; the cylindrical section of the bullet is a tubular structure having periodically alternating transverse and vertical holes; the tubular structure includes a plurality of holes, with a center axis of one hole being axially perpendicular to a center axis of another adjacent hole, that is, the axis of each hole being structurally orthogonal to an adjacent hole; and the holes in rows and columns are periodically arranged into the tubular structure, which is a tubular structure having the negative Poisson's ratio effect.

An example method includes obtaining a geometric compensation profile characterising a relationship between a location of an object within a first fabrication volume having a first depth of build material and a geometrical compensation to be applied to a model of said object. The method further includes determining that a first object is to be generated in a first build operation having a second fabrication volume which has a second depth. The method may further include determining a geometrical compensation to be applied to a model of the first object by: determining a first offset of the first object from the top of the second fabrication volume; identifying the geometrical compensation value associated with a location having the first offset from the top of the first fabrication volume; and determining the compensation to be applied to the model of the first object based on the identified geometrical compensation value.

A gear-based mechanical metamaterial with continuously adjustable elastic parameters in a large range is provided. The gear-based mechanical metamaterial includes a gear array, a frame and connecting shafts. The gear array is formed by periodically extending mechanical metamaterial cells along an x direction and a y direction. Each of the mechanical metamaterial cells is formed by arranging a multiple gears. Adjacent gears of the multiple gears are meshed with each other. Each of the multiple gears includes a center hole and two centrosymmetric irregularly-shaped holes. A thickness of an elastic arm between the each of two centrosymmetric irregularly-shaped holes and an outer wall of a corresponding one of the multiple gears is uniformly increased or decreased. Each of the connecting shafts is arranged in a center hole of a corresponding one of the multiple gears.
