Combining the techniques of discrete event simulation and virtual-reality, research on real-time interactive simulation for concrete dam construction process is conducted, under the virtual-reality environment. The key technologies are discussed, including the modeling of DEM, optimization for real-time displaying of 3D scene, collision checking, real-time interaction and so on. A framework for the system of virtual-reality simulation for concrete dam construction operations based on Vega is presented. Virtual-reality supplies for construction simulation with a real-time interactive 3D simulation environment to inspect the validity of simulation model, which improves the simulation credibility and becomes a helpful tool for real-time decision making of construction operations. An example is performed to illustrate the feasibility of the system.

Object Of Study

The present work presents a research carried out with 6th and 7th grade students of Elementary School II at Escola Municipal Mon. Walfredo Gurgel Alto do Rodrigues/RN, aiming to encourage the use of materials such as Ruler and Square in Mathematics classes and to know your opinion about the use of Augmented Reality and Virtual Reality glasses. This aimed at a reflective analysis of how the inclusion of technologies in education can enhance learning when the use of multimedia resources that help in understanding mathematical concepts or that enable a dynamic visualization of the object of study are encouraged. She seeks to know what the contribution of this device to the teaching and learning process of Mathematics. Methodologically, the work is characterized as an exploratory research of qualitative and quantitative nature, with a bias towards a case study, with data collected through a semi-structured questionnaire with 102 students. We can count on an interdisciplinary planning to present the programmed contents with more meaning. The results were analyzed based on the research instruments and the testimonies of the students, in addition to a brief study on information and communication technologies applied to learning. Thus, the data are organized in graphs where the research findings are expressed.

The Relationship

The paper describes a method for the immersive, dynamic visualization of undirected, weighted graphs. Using the Fruchterman-Reingold method, force-directed graphs are drawn in a Virtual-Reality system. The user can walk through the data, as well as move vertices using controllers, while the network display rearranges in realtime according to Newtonian physics. In addition to the physics behind the employed method, the paper explains the most pertinent computational mechanisms for its implementation, using Unity, SteamVR, and a Virtual-Reality system such as HTC Vive (the source package is made available for download). It was found that the method allows for intuitive exploration of graphs with on the order of [Formula: see text] vertices, and that dynamic extrusion of vertices and realtime readjustment of the network structure allows for developing an intuitive understanding of the relationship of a vertex to the remainder of the network. Based on this observation, possible future developments are suggested.

It is established a visualization simulation mechanism of dam construction process at first. Then terrain contours are converted into grid mesh by contours discrete method to establish the terrain model. The 3D dam model, foundation pit, construction road are built. Then the dam model is digitalized to create the dam database. After that, all of the models are rendered by using 3DSMax, and then documents of models and materials are exported with a plugin of OgreMaxSceneExporter to assure that they can be identified by an effective graphics rendering engine--OGRE. Finally, a dam construction process visualization system for a practical case is developed, by which an interactive virtual reality environment is created for engineers and administrators.
