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 ...

An Accelerated Slicing Algorithm for Frep Models
Applied Sciences, 2021 Complex 3D objects with microstructures can be modelled using the function representation (FRep) approach and then manufactured. The task of modelling a geometric object with a sophisticated microstructure based on unit cell repetition is often too ...

Toward the Assessment of Intrinsic Geometry of Implicit Brain MRI Manifolds
IEEE Access, 2021 Principal and Gaussian curvatures are commonly used intrinsic metrics for geometric morphometrics analysis: to assess morphometric changes in brain geometry (developmental neuroimaging studies), to quantify shape deformation (organ motion assessment), or

Computation of Implicit Representation of Volumetric Shells with Predefined Thickness
Algorithms, 2021 We propose and validate a method to find an implicit representation of a surface placed at a distance h from another implicit surface. With two such surfaces on either side of the original surface, a volumetric shell of predefined thickness can be ...

Implicit surfaces that interpolate [PDF]
Proceedings International Conference on Shape Modeling and Applications, 2002 Implicit surfaces are often created by summing a collection of radial basis functions. Researchers have begun to create implicit surfaces that exactly interpolate a given set of points by solving a simple linear system to assign weights to each basis function.

LIMOFilling: Local Information Guide Hole-Filling and Sharp Feature Recovery for Manifold Meshes
Remote Sensing, 2022 Manifold mesh, a triangular network for representing 3D objects, is widely used to reconstruct accurate 3D models of objects structure. The complexity of these objects and self-occlusion, however, can cause cameras to miss some areas, creating holes in ...

MDISN: Learning multiscale deformed implicit fields from single images
Visual Informatics, 2022 We present a multiscale deformed implicit surface network (MDISN) to reconstruct 3D objects from single images by adapting the implicit surface of the target object from coarse to fine to the input image.
