Scene space意思

"Scene space" is a term used in computer graphics and 3D modeling to refer to the three-dimensional coordinate system in which a scene is represented. It is the space in which the objects, lights, cameras, and other elements of a 3D scene are placed and interact with each other.

In scene space, each object in the scene is assigned a set of coordinates that define its position, orientation, and size within the scene. These coordinates are used to calculate the object's visibility, shadows, reflections, and other visual properties, as well as to determine how the object will interact with other objects in the scene (e.g., by colliding with them, casting shadows on them, or reflecting light from them).

Scene space is typically defined relative to a coordinate system that is centered on the origin (0, 0, 0) and extends in the positive and negative directions of the x, y, and z axes. The size and orientation of the scene space can vary depending on the specific needs of the scene and the software or hardware being used to render it.
