Ray Zone

Ray Zone is a term referring to the area or volume of space closest to the source of a ray, typically in the context of ray tracing or ray casting algorithms used in computer graphics. Within the Ray Zone, calculations related to ray behavior, such as intersection tests with objects in the scene, are most computationally sensitive and often require specialized handling. It is often an area where precision and performance trade-offs are carefully managed. The definition of the boundary of the Ray Zone can vary depending on the specific implementation and application. It's conceptually analogous to the near clipping plane in rendering.
