Clipping planes let you exclude some of a scene's geometry to view or render only certain portions of the scene. Each camera has a near and a far clipping plane. Objects closer than the near clipping plane or farther than the far clipping plane are invisible to the camera.
Clipping planes are useful for rendering selected portions of a scene that have a lot of complex geometry. They can also help you create cutaway views.
Clipping plane settings are part of the camera's creation parameters. The location of each clipping plane is measured along the camera's line of sight (its local Z axis) in the current units for the scene.
Clipping planes are part of a camera’s general parameters.
Viewports can also have clipping planes. You set a viewport’s clipping planes via the viewport right-click label.
