Professional production of electronic sand table, sand table projection effects, interactive sandbox system, sandbox interaction, laser pointer sand table, sand table model making, video sandbox synchronous systems, lighting sandbox interactive 189-4223-3130 President Nah 400-0791-138 various traditional crafts sandbox model, very widely used in military command, traffic control, teaching and research, museums, gardens planning. But there are also complex process, high production costs, long production cycle, difficult to ensure accuracy, inconvenient transportation and other issues, and once made, sand table model was cured, modified very inconvenient. Digital sandbox is a sand table model based on three-dimensional virtual simulation technology computable information of immersive interactive environment. Specifically, the use of computer technology as the core of modern high-tech means to generate realistic visual, virtual environment to listen to the integration of a specific range, the user with the necessary human interaction devices (mouse, steering wheel and other external accessories), large-screen display Device (multi-screen projection display, an annular projection display, a spherical projection display), three-dimensional model on the natural way with a large screen / virtual context objects interact and influence each other, resulting in feelings of real environment and person equivalents experience. Three-dimensional visualization of virtual simulation GIS digital sandbox can also integrate remote sensing (RS), geographic information systems (GIS) and three-dimensional simulation technology (VR) established. Compared with traditional digital sandbox sand table model, its broader applications, fast, simple, precise features, and can be dynamically presentations, real-time updates and fast and easy parameter query revised to obtain a richer presentation effects, its terrain geography and geology geomorphology and other landscape show more intuitive three-dimensional virtual simulation demonstration effect. The main advantage of the performance: from the site constraints; performance effect is more beautiful, realistic, and highly interactive, three-dimensional virtual simulation into the virtual environment, just as immersive. In addition, also the digital sandbox with the physical model of the three-dimensional virtual simulation seamless combination really do interactive interactive, so that the whole system alive.
