Although the shape and distribution of aggregate in the model built by this method are closer to the real structure of concrete, there is still a big difference between them and the real concrete specimen. In order to solve the problem of large amount of redundant computation in the CT reconstruction of full size cube space, a fast reconstruction method based on ray-casting algorithm is proposed. First, a method integrating the new bounding box technology with the plane intersection algorithm clusters were adopted to cut the body data and ray-casting effectively, and then, the polygon scanning and conversion was utilized to reduce the number of cast rays, finally, the adaptive sampling method was used to avoid repeatedly sampling same voxel so that the reconstruction efficiency of whole algorithm and the feasibility of numerical calculation can be enhanced. The experimental results demonstrate that the proposed algorithm can greatly improve the 3D rendering speed of concrete CT without affecting the image quality. It provides a more effective and reliable approach for correctly analyzing the mesoscopic damage mechanism and mechanical characteristics of concrete. <\/jats:p>","DOI":"10.1142\/s0218001417570051","type":"journal-article","created":{"date-parts":[[2017,3,16]],"date-time":"2017-03-16T15:27:25Z","timestamp":1489678045000},"page":"1757005","source":"Crossref","is-referenced-by-count":4,"title":["Concrete CT Image Quick Three-Dimensional Reconstruction Research"],"prefix":"10.1142","volume":"31","author":[{"given":"Liang","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Info and Automation, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, P.
