Where are sand tables mainly used?

1． Terrain sand table:

The terrain model represents the terrain features in the form of miniature entities, and embodies mountains, water bodies, roads, etc. in the model. It mainly expresses terrain data, allowing people to view it from a microscopic perspective. perspective to understand macroscopic things. The application scope of terrain models is extremely wide. The main industries used include: government, transportation, water conservancy, electric power, public security command, land resources, tourism, human resources, military, etc.

2. Architectural Sandbox:

Architectural models represent architectural art in the form of miniature entities. Whether it is a single shape or a group combination, they are structures that faithfully express architectural ideas and incorporate the architect's intentions. transformed into concrete images.

3． Electronic sand table:

The electronic sand table uses real three-dimensional geographical information data and advanced geographical information technology to dynamically search the geographical information of each point in real time. Such as three-dimensional coordinates, height, slope, rivers, roads and various artificial projects and facilities, long-term planning and other information. And through the advanced three-dimensional simulation function, it can conduct three-dimensional single-point flight, path flight, orbiting point flight, engineering facility inquiry, economic benefit analysis and other various intelligent analyzes in real time on the computer. It is suitable for units that are closely related to geographical terrain, such as the site selection of mobile communications and the planning and construction of large-scale water conservancy facilities. Electronic sandboxes are divided into three-dimensional electronic sandboxes, acousto-optical sandboxes and multimedia touch sandboxes. It is composed of multimedia computer (touch screen all-in-one machine), logic controller, driver, stage lighting controller and touch remote control (PDA handheld computer) and other equipment. It cooperates with model sand table, large screen projection and multimedia display software to realize Model lighting and stage lighting actions are controlled automatically, manually, and remotely, and various related information in the model sandbox is simultaneously displayed in multimedia forms such as voice, text, pictures, and video images to achieve a comprehensive interactive multimedia display effect.

The model sand table and the application of computer intelligent display control system in the exhibition hall are a high-tech and creative design. It allows the public to understand the content displayed on the model sand table vividly, vividly, quickly and accurately, and can effectively achieve the purpose of displaying it to the public. It covers the needs of viewers based on reality: voice introduction, touch intelligence, lighting special effects, remote control and other intelligent technologies, making the exhibition hall full of vitality, intelligent, colorful, convenient for display and modification and other functions.

a. Three-dimensional interactive virtual real estate - an architectural model placed in the computer

Three-dimensional interactive virtual real estate is a real estate pre-sale tool that can upgrade and replace architectural models and model houses. It uses The design drawings and material data provided by the real estate developer will accurately simulate the proposed building on the computer at a 1:1 ratio. The super-large scene and partial rendering will create shocking audio-visual effects and improve on-site sales performance. Customers can enter the virtual real estate in the sales department or on the website, and walk around and fly in the virtual real estate like playing a game. They can also enter the room they like to check the decoration effect, and also understand the surrounding environment, transportation, location, development company's strength, mortgage calculation amount, etc. The system can automatically generate three-dimensional cartoons for broadcast in the sales department and for television advertising.

b. Multimedia Sandbox

The multimedia sandbox can three-dimensionally display the mountains, rivers, topography and landforms in the area under the jurisdiction of the government or department at the same level, and reflect the departments and departments under the government at all levels in various forms. Various command elements. Using computer multimedia control technology, the sound (commentary), light, image, and subtitles can be displayed synchronously or asynchronously. It can be controlled by remote control, hand control, induction, or multimedia control; it can be digitally displayed, single-point displayed, or combined. display, dynamic display, and remote video monitoring display using only one telephone line. It has the characteristics of flexible operation, simplicity, easy maintenance and modification.
