“…In the work by Angles et al 71 , a bundle of cosserat rods was used as an alternative to tetrahedral meshes for modelling muscles and PBD simulation of volume invariant rods was coupled to a surface mesh to simulate soft-body deformation with high efficiency. Without using tetrahedral meshes, triangle meshes were deformed via a Verlet integration framework of PBD simulation to reduce the computational cost, which provides the simulation of deformable surfaces on the selected area of the 3D mesh with a desired range 72 .…”

The emergence of position-based simulation approaches has quickly developed a group of new topics in the computer graphics community. These approaches are popular due to their advantages, including computational efficiency, controllability, stability and robustness for different scenarios, whilst they also have some weaknesses. In this survey, we will introduce the concept of the baseline position based dynamics (PBD) method and review the improvements and applications of PBD since 2018, including extensions for different materials and integrations with other techniques.

“…Based on the theory of interactive mesh deformation, the constrained deformation approach involves the inputting of an orebody mesh model and several control polylines, and the construction of constraint deformation conditions, to realize local mesh deformation and update the orebody model. Over the years, many scholars have conducted relevant research on interactive mesh deformation [24] and optimization [25] in the fields of medicine, mechanics, graphics, etc. For example, Qin et al [26] presented an example-driven mesh deformation method and introduced a feature representation of a rotation-invariant reconstruction framework to accurately reconstruct vertex positions, and the feature representation allowed interpolation and extrapolation.…”

In this paper, to update the orebody model based on the given interpreted geological information, we present a local dynamic updating method of the orebody model that allows the interactive construction of the constraint deformation conditions and the dynamic updating of the mesh model. The rules for constructing deformation constraints based on the control polylines are discussed. Because only part of the model is updated, the updated mesh is effective and the overall quality is satisfactory. Our main contribution is that we propose a local dynamic updating method for the orebody model based on mesh reconstruction and mesh deformation. This method can automatically update a given 3D orebody model based on a set of unordered geological interpretation lines. Moreover, we implement a deformation neighborhood region search method based on the specified ring radius and a local constrained mesh deformation algorithm for the orebody model. Finally, we test the method and show the model update results with real geological datasets, which proves that this method is effective for the local updating of orebody models.
