An adaptive implicit surface reconstruction method for three-dimensional point cloud
Based on adaptive octree and improved differential evolution algorithm, an implicit surface reconstruction method for three-dimensional point cloud data is presented.Firstly, the original point cloud is adaptively segmented by octree. Secondly, the local

A study of morphology of silicon with femtosecond laser based on phase field model
In this paper, phase field model is employed to simulate the process of femtosecond laser which irradiates on silicon surface. The numerical model is mainly used to study the micro/nano evolution process and the atomic diffusion motion of the system ...

Control Modification of Grasp Force Covaries Agency and Performance on Rigid and Compliant Surfaces
This study investigated how modifications in the display of a computer trace under user control of grasp forces can co-modulate agency (perception of control) and performance of grasp on rigid and compliant surfaces.

Isotopic meshing of implicit surfaces [PDF]
Implicit surfaces are given as the zero set of a function F : R3→R. Although several algorithms exist for generating piecewise linear approximations, most of these are based on a user-defined stepsize or bounds to indicate the precision, and therefore cannot guarantee topological correctness. Interval arithmetic provides a mechanism to determine global

Neural 3D reconstruction from sparse views using geometric priors
Sparse view 3D reconstruction has attracted increasing attention with the development of neural implicit 3D representation. Existing methods usually only make use of 2D views, requiring a dense set of input views for accurate 3D reconstruction.

MixNet: Mix different networks for learning 3D implicit representations
We introduce a neural network, MixNet, for learning implicit representations of 3D subtle models with large smooth areas and exact shape details in the form of interpolation of two different implicit functions.
