Selection by polygons, cleaning, separation, fusion of clouds or meshes
During the digitalisation of a model, it happens very often that the scanner takes points which are really irrelevant. These points can come from reflection on surface (measurement noise) or from the digitalisation of the support on which is laying the model.
When they are too numerous, these points can perturbate the meshing process and entail a poor 3D mesh quality. 3DReshaper® thus proposes a cleaning option, available for point clouds and for meshes (by triangle selection).
It is also possible to separate point clouds and 3D meshes or to merge them. The mesh separation is very useful when we want to treat separately two parts of one single set. This segmentation process is especially interesting when two parts of the same object contain two really different levels of details. In this case, it may be more relevant to segment the model in two parts and to process them separately with specific parameters.
