Point Clouds Based Dynamical Representation for Heterogeneous Objects

Abstract:

An approach of point clouds based dynamical representation for Heterogeneous Objects (HEO) is proposed to describe the HEO, in which materials distribution is uniformed or irregular. Mesh refined STL model and micro-tetrahedral cell are employed to rebuild HEO geometry. Meanwhile, distribution property, volume fraction and distribution vector are used to represent material features of HEO nodes within each material layer. Therefore, after implementing the above interrogation process layer by layer, HEO geometry and material composition representation can be defined. The approach is effective and practicable through some numerical examples demonstrated based on developed HEO fabrication system.
