Embodiment Construction

[0044] It provides a computer-implemented approach to civil engineering.

[0045] In particular, it provides the first computer-implemented method for civil engineering.

[0046] The first method involves providing a mesh representing the terrain. The first method also includes computing a watershed segmentation of the terrain based on the grid. Computation of the watershed segmentation involves identifying one or more saddle points on the mesh. Computation of the watershed segmentation also includes, for each identified saddle point, identifying paths ascending from the saddle point according to the direction of the local maximum slope around the saddle point and paths descending from the saddle point according to the direction of the steepest slope around the saddle point. The identified ascending paths divide the mesh into connected components. Computing the watershed segmentation also includes, for each identified saddle point, merging each connected component whose bot...

Abstract

The invention relates to a computer-implemented method for civil engineering. The method comprises providing a mesh representing a terrain. The method further comprises computing a watershed segmentation of the terrain based on the mesh. The computing of the watershed segmentation includes identifying one or more saddle points on the mesh. The computing of the watershed segmentation further includes, for each identified saddle point, identifying paths each ascending from the saddle point according to a direction of a local maximal slope around the saddle point, and a path descending from the saddle point according to a direction of a steepest slope around the saddle point. The identified ascending paths divide the mesh into connected components. The computing of the watershed segmentation further includes, for each identified saddle point, merging each connected component of which bottom point is the saddle point with a connected component comprising the identified path descending from the saddle point according to a direction of a steepest slope around the saddle point. The merging yields at least a part of a basin.

Description

technical field [0001] The present disclosure relates to the field of computer programs and systems, and more particularly to methods, systems and programs for civil engineering. Background technique [0002] Many systems and programs for the design, engineering and manufacture of objects are available on the market. CAD is an acronym for Computer Aided Design, as it relates to software solutions for designing objects. CAE is an acronym for Computer Aided Engineering, for example it concerns software solutions for simulating the physical behavior of future products. CAM is an acronym for Computer Aided Manufacturing, as it relates to software solutions for defining manufacturing processes and operations. In this CAD system, GUI plays an important role in technical efficiency. These technologies may be embedded in product lifecycle management (PLM) systems. PLM refers to a business strategy that helps companies share product data, apply common processes, and leverage corp...
