Implicit modeling of narrow vein type ore bodies based on Boolean combination constraints [PDF]
Scientific Reports, 2022 In this paper, we implement an automatic modeling method for narrow vein type ore bodies based on Boolean combination constraints. Different from the direct interpolation approach, we construct the implicit functions of the hanging wall and foot wall ...

Combination Constraints of Multiple Fields for Implicit Modeling of Ore Bodies
Applied Sciences, 2021 In this paper, we introduce combination constraints for modeling ore bodies based on multiple implicit fields interpolation. The basic idea of the method is to define a multi-labeled implicit function that combines different sub-implicit fields by the ...

Geological Modeling Method Based on the Normal Dynamic Estimation of Sparse Point Clouds
Mathematics, 2021 The effect of geological modeling largely depends on the normal estimation results of geological sampling points. However, due to the sparse and uneven characteristics of geological sampling points, the results of normal estimation have great uncertainty.

Toward a Simple Design and Manufacturing Pipeline for Additive Manufacturing
IEEE Access, 2021 A novel design and manufacturing pipeline for Additive Manufacturing is presented. The architecture of the pipeline is motivated by the observation that the conventional pipeline is unnecessarily complex. Most of the time, only a small set of programming

Orebody Modeling Method Based on the Normal Estimation of Cross-Contour Polylines
Mathematics, 2022 The normal estimation of cross-contour polylines largely determines the implicit orebody modeling result. However, traditional methods cannot estimate normals effectively due to the complex topological adjacency relationship of the cross-contour ...
