3D Tiles are a type of digital data format used for visualizing and interacting with 3D geographic data. They consist of small, individually rendered 3D graphics or models, known as tiles, that can be combined to create a larger, more detailed 3D representation of a given area or object.

Designing 3D tiles involves a combination of artistic and technical skills. 3D tiles refer to a data format for 3D geospatial data that can be used in 3D mapping and visualization applications. In 3D mapping, 3D tiles are used to represent and display 3D models of real-world objects, such as buildings, trees, and terrain. The 3D tiles format allows for efficient streaming and rendering of large 3D models over the web, allowing users to interact with 3D maps in real-time. The 3D tiles format is based on the concept of "tiling", where a 3D model is divided into small, rectangular regions called "tiles". Each tile contains a portion of the 3D model's geometry and texture data, and is designed to be loaded and rendered on-demand as the user navigates through the 3D scene.

3D tiles are commonly used in applications that require high levels of detail and interactivity, such as virtual reality experiences, video games, and GIS (Geographic Information System) applications. They allow users to explore and manipulate 3D data in real-time, making it easier to visualize complex spatial relationships and understand the layout of an environment. One of the key advantages of 3D tiles is their ability to be streamed and loaded on-demand, which makes them highly efficient and scalable for large datasets. This means that users can access and interact with high-quality 3D data without the need for extensive computing resources or specialized software.

Overall, 3D tiles offer a powerful and flexible tool for visualizing and working with 3D geographic data, making them an increasingly popular choice in a wide range of industries and applications.
