Description: Normalized Device Coordinates (NDC) are a coordinate system used in graphic rendering that allows points in a three-dimensional space to be represented in a standardized manner. In this system, coordinates are normalized to a range from -1 to 1 on the X, Y, and Z axes. This means that any point within the viewing volume can be expressed in terms of these normalized coordinates, thus facilitating the transformation and projection of 3D objects onto a 2D surface, such as a computer monitor. NDC are fundamental in the graphics pipeline, as they allow graphics to be independent of screen resolution and size, simplifying the rendering process. Additionally, this system is crucial for implementing clipping and culling techniques, which optimize performance by removing parts of the scene that are not visible to the viewer. In summary, NDC are an essential component in modern graphic representation, providing a coherent framework for the manipulation and visualization of three-dimensional data in various digital environments.
