1) presentation effect: ordinary sand table covers an area of large, high replacement cost, the site can not be flexible and changeable; digital sand table site can be reused many times, real-time switching sand table theme, more interactive, every graphic element in the space and data information can be synchronized with real-time updates.
2) Visual aspect: the traditional sand table is relatively "rigid", displaying a single form; digital sand table display mode is flexible, displaying a wide range of content, shocking scene, attracting eyeballs, alive, displayed in front of the public, and can interact with the user.
3) Flexibility: the traditional sand table is fixed, the replacement cost is high, the venue can not be flexible; digital sand table not only across the boundaries of space, but also across the time change, the content at any time to replace the seasons at any time to change.
According to Baidu's encyclopedia, digital sand table is mainly divided into two kinds:
One is to increase the multimedia projector system on the original traditional sand table model;
The second one is a pure three-dimensional digital sand table, generally with interactive features, the projection surface is generally a special treatment of white or gray screen, with a solid sand table model. Through the sound, light, electricity, images, three-dimensional animation and computer program control technology and entity model integration.
Features:
Digital sand table has a wide range of display content, exquisite design techniques, advanced means of display, high technology content.
Digital sand table in the content of the display is simple and clear, not a commonplace, the design of both the traditional innovation, but also the embodiment of modern high-tech, large models of the scene is grand, small models of the layout of the exquisite. A large number of high-tech display methods, sound, light, electricity, interactive projects, three-dimensional animation, film and television and other modern visual effects. Combined with the fun, interactivity and knowledge, the exhibition is fun, realizing the "interactive revolution" with the audience. Digital sand table has a control system, including the overall control, hall lighting, lighting, computers, televisions, operating tables and air-conditioning and other strong and weak power systems in accordance with the pre-programmed operating procedures to run automatically, from the power to open and close the power supply, do not need to be controlled by human beings, automatic operation.
Practical application:
Real estate showroom
The sand table is indispensable to the real estate showroom, and in this era of serious information overload, we need the sand table with a new look to show people, so as to win more audience's eyes, thus increasing the number of potential consumers. Multimedia projection sand table through rigorous design, to achieve multi-functional synchronous linkage, call sand table LED lighting, dynamic projection video, large arc screen and other sub-equipment, the best side of the property to show the best.
Urban Planning Pavilion
Digital sand table is a revolutionary innovation, based on the traditional solid sand table, adding a variety of multimedia sound and light means mainly based on dynamic projection, which breaks people's impression of monotonous and stereotypical sand table.
In the city planning hall, the most indispensable is the sand table. The sand table is a miniature of the city, providing the audience with a bird's-eye view of the city, an overview of the whole situation. But the traditional sand table model can only show the city in a time dimension, for a few years or even decades of urban planning, the expressive power is far from enough. The digital sand table can dynamically show the whole picture of a city, jumping and changing in different time dimensions, which is the best tool to elaborate a city plan.
Troops
Digital sand table is one of the essential equipments in army command and operation. Traditional paper maps show all kinds of information is more abstract, the commander will be slightly negligent misjudgment, omission and so on, and then affect the combat effect. Recommended in the major command places to set up combat sand table, mountains, rivers, roads and bridges in the sand table simulation display, so that the troops on the local terrain more understanding, so that the combat plan of the commanders can be more vivid, clear display
Digital interactive sand table
Digital interactive sand table is a computable information based on the immersive interactive environment of three-dimensional virtual simulation technology Nolide sand table Model, through the touch screen, lighting, image technology and physical sand table combination, vivid display of the theme content, and can set up interactive control points and by the audience to independently select the content of the display area, or by the program control to play on their own.
