“…Then, Adeli and Kamal (2008) achieved over 90% efficiency improvement by employing the Parallel Threads on 11 Encore processors for the structural analysis on two space truss examples. Given the importance of the section views, Yang et al (2003) developed a fast cutting method for a finite element model by using hybrid considerations of both volume data and geometric surfaces.…”

“…The 3D cutting (or 2D-plane cutting) for section view is one of the key processing techniques for the design analysis of CID and for exploring the data distribution inside structures, as being introduced by Yang et al (2003). In particular, for the modern building information modeling design, the 3D cutting-based section view is an important reference for observing the details and validating the correctness of the design.…”

With the advancement of the three-dimensional (3D) modeling techniques in the recent decade, civil infrastructure design (CID) has been used to produce large-scale 3D infrastructure models that contain a large set of 3D models with a significantly large number of vertices. In the meantime, such large-scale data necessitates a higher requirement for efficient data processing techniques. Twodimensional (2D)-plane cutting is one of the basic techniques used to observe and analyze 3D models in CID. This paper presents an efficient cutting scheme for a section view of large-scale 3D infrastructure models in CID. The proposed cutting scheme contains a pipeline of locating the intersected faces, computing the intersection points, and the polygon triangulation for visualization. Furthermore, an optimized data structure is introduced to realize the parallel implementation of the efficiency cutting scheme. After integrating to our existing 3D design and visualization platform, the experimental results with different 3D infrastructure model datasets, such as the large-scale electrical substation models, have demonstrated both the effectiveness and the efficiency of the proposed cutting scheme.

“…Typical spline surfaces include Bezier surface (Eschenauer, 1995;Rajan et al, 1996), B-spline surface (Anand, 1993), and Non-Uniform Rational B-Spline (NURBS) (Dimitrov et al, 2016). Implicit surface method (Liu et al, 2017) generates surfaces by implicit functions such as isosurface (Yang et al, 2003) and convolutional surface (Kim et al, 2003).…”

Free‐form grid structure is a kind of structure whose shape cannot be expressed by analytical functions. Although this kind of structure has been widely used in practice, how to generate the structural shapes that not only satisfy architectural requirements but also have excellent mechanical properties is still a problem. This article focuses on the shape generation of complex grid structures and proposes a novel shape‐generation method for free‐form grid structures. The method integrates numerical inverse hanging method and multiobjective optimization. First, it uses numerical inverse hanging method to generate structural shapes in low bending moment level. Next, it uses dynamic weight multiobjective firefly optimization algorithm to adjust the parameters of the inverse hanging method adaptively so that the structural shape can satisfy architectural requirements. Comparisons with former shape‐generation methods show that the proposed method is more effective. Numerical examples based on real structures illustrate the applicability of the proposed method in practice.
