Heterogeneous Object Modeling Approach Based on ACIS and HOOPS

Abstract

This paper deals with the background and significance of working on heterogeneous objects modeling and briefly introduces the architecture of ACIS and HOOPS and their corresponding functional modules. Based on inverse-distance weighting algorithm to determine the material composition within the object, the general approach to modeling the heterogeneous objects by using ACIS and HOOPS is introduced and demonstrated via some simple examples.

A CAD/CAE incorporate software framework using a unified representation architecture

“…ACIS provides an open architecture framework for wireframe, surface and solid modeling from a common, unified data structure. HOOPS is developed by Tech Soft 3D and technically supported by Spatial [42,45]. ACIS has the great advantage over HOOPS in geometric modeling.…”

“…ACIS is the 3D modeling kernel of the Spatial Corp, which is an objected-oriented 3D geometric modeling engine (Spatial Corporation, USA) [42]. The ACIS model is highly redundant to enable efficient geometrical and topological operations [43].…”

Virtual 3D Ink-Jet Printing System for Heterogeneous Object

“…Heterogeneous Object(HO) 1,2 refers to a solid component consisting of two or more primary materials distributed continuously or discontinuously within an object, which is usually classified into three categories 3 : multiple material object (MMO), object with embedded components (OEC) and functionally graded material object (FGMO). The mechanical parts with heterogeneous material often perform series of composite function and these advantages make HO materials widely used in aerospace industry, nuclear energy, microelectronics, bio-medical engineering and other fields [1][2][3] .…”

An approach to representing heterogeneous non-uniform rational B-spline objects

“…Most of the existing HO representation methods [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] suffer from some obvious limitations on the objects with freeform surfaces, especially for non-uniform rational Bspline (NURBS) surface. B-spline representation introduced by Yang and Qian [22,23] can represent B-spline heterogeneous curves and surfaces, but it is not fit for the elementary surfaces such as conicoid and plane.…”
