Compared to traditional physical sand table models, 3D projection sand tables have a broader range of applications. They are characterized by speed, simplicity, and precision, enabling real-time dynamic display, updates, and queries. They also allow for easy parameter modifications and deliver richer presentation effects. Their main advantages include: no limitations imposed by physical sites; more aesthetically pleasing and vivid visual effects; strong interactivity; and the ability to provide visitors with extensive information and an immersive interactive experience. By integrating remote sensing (RS), geographic information systems (GIS), and 3D simulation technology (VR), projection sand tables are created. Moreover, the interactive projection of 3D digital sand tables can be seamlessly combined with traditional physical sand table models, where true interaction brings the entire system to life.

The 3D digital projection sand table, also known as the digital sand table projection system or virtual 3D digital sand table, can be divided into two categories: the combination of physical models with virtual imagery, and fully virtual sand tables. The so-called projection sand table is a modern high-tech method that uses computer technology as the core to generate realistic 3D image models. With the help of projection display devices or other display equipment, 3D or 4D graphic image models from the computer are displayed on a tabletop, wall, floor, or other surfaces.

Specifically, simulated 3D images can be accurately projected onto corresponding positions of physical models. For example, a 3D vehicle animation can be projected onto the actual roads of a physical sand table, and the physical sand table’s display can reflect dynamic lighting effects, making the presentation more vivid and engaging. Visitors can interact with the large-screen projected 3D models through natural gestures, enabling multi-directional and multi-level browsing and querying, thereby quickly obtaining concise, accurate, aesthetically pleasing, and realistic dynamic information.
