在几何学中,Point、Line、Plane和Solid是几何图形的四个基本要素。Point是构成Line的基本要素,Line是由无数个Point连接而成的,Plane则是由无数个Line连接而成的,Solid则是由无数个Plane连接而成的。这四个基本要素构成了几何空间中的所有物体。 3.2点的坐标 在代数学中,Point通常表示为一个坐标,如(x, y)。坐...

this paper attempts to expand the concepts of equations and solutions in the way of referring to the concepts of domain of function, the geometry elements included in domain of function, and the like; and discusses point equation, line equation, plane equation, solid equation, sub-...
1, corner points (red) are detected when the tip of a skeleton branch (blue line) touches the building boundaries (black). However, generating a MAT skeleton from point clouds is a challenging problem as such data contain fuzzy borders, in particular, when data is missing [25]. This ...
8 Points: The same functionality as the other two tools, but this time with the ability to draw 4 reference lines, which is useful when you want to affect elements in the image that are not on the same plane or at the same distance. You can also use this to force a rectangle. ...
10.7. In the left panel, the linear array transducer is drawn as a red line at the top of the green rectangle that represents the field of view. Here, the medium is uniform except for some strong point scatterers drawn as black dots. The array emits a steered plane wave that first ...
Using dimensional analysis of the plumes from point, line and infinite plane buoyancy sources, it is shown how the different source geometries lead to diff... LA Peletier,J Zhao - 《Nonlinear Analysis》 被引量: 104发表: 1990年 Coherent vortical structures in numerical simulations of buoyant plu...
It is based on the prior that both models have at least one common tangent plane on which both can stand stably and when standing on it the models are partially aligned. To determine the final rotation around the stable plane's normal, needed for a complete alignment, we adapt an image ...
This study aims to utilize the hybrid solid-state LiDAR (SSL) point cloud to achieve pavement 3D reconstruction and overcome the stratification problem of the pavement point cloud. A low-cost Mobile Laser Scanning (MLS) system based on the hybrid SSL is constructed beforehand. Then, a region ...
Point defects are a universal feature of crystals. Their identification is addressed by combining experimental measurements with theoretical models. The standard modelling approach is, however, prone to missing the ground state atomic configurations asso
