A prism is a 3D shape which has a constant cross section - both ends of the solid are the same shape and anywhere you cut parallel to these ends will give you the same shape. For example, in the prism ...

A cross section is the shape formed when a plane intersects a three-dimensional figure. Imagine slicing through a solid object with a knife; the shape of the slice is the cross section. Understanding ...

Abstract: Digital watermarking uses the redundant information of protected data to embed some practical information or serial numbers into carrier data through a series of algorithms. These secret ...

Abstract: Three-dimensional (3D) triangular meshes has been widely used in tunnel engineering. This paper proposes an algorithm for unwrapping 3D tunnel lining meshes into straight two-dimensional (2D ...
