In this paper, an approach named isovolume extraction for 3D Data Sets rendering is presented. This approach extracts and visualizes a model that meets the desired range property values. It extends previous visualization techniques and is very suitable for closed objects extraction. After deeply studying the centroid-based isovolume extraction algorithm proposed by David J. Russomanno et.al, authors...
Urban 3D geological survey has become a new developing direction in the domain of geology. One of primary purpose of such project is to build urban geological information system which is able to provide different geologic information representation forms for people with different geologic knowledge background. Data-information-knowledge-wisdom (DIKW) hierarchy based urban geological information visualization...
This paper presents a novel arbitrary cut algorithm based on 3D geological objects represented by TIN structure. The geological model is composed by a series of TIN surfaces. Compared with the classical cut algorithm, the algorithm brings some obvious improvements on the following two aspects: the generation of arbitrary section and the partition of cut geological bodies. According judging the position...
