Description: The projection surface is the physical area onto which a three-dimensional image or video is projected. This surface can be any material that allows for clear visualization of the projection, such as screens, walls, or tables specifically designed for this purpose. In the context of 3D visualization and augmented reality, the projection surface becomes a crucial element, as it not only serves as a visual support but can also interact with advanced technologies that allow for the overlay of digital elements onto the real world. The characteristics of the projection surface include its texture, color, and ability to reflect or absorb light, which influences the quality of the projected image. Additionally, in augmented reality applications, the surface may be touch-sensitive or interactive, allowing users to manipulate virtual objects intuitively. Thus, the projection surface is not just a backdrop for visualization but an active component in the immersive experience offered by modern technologies.
