Out of plane是什麼意思

"Out of plane" is a term used in various fields, such as engineering, physics, and mathematics, to describe a position or orientation that is not within a specified plane or two-dimensional surface. The meaning can be a bit context-dependent, but here are some general interpretations:

In engineering and manufacturing, "out of plane" might refer to a component or object that is not aligned with a designated reference plane or is not parallel to a certain surface. This term is often used in reference to parts that are supposed to fit within a specific plane, such as in a sheet metal assembly or a structure where parts need to be precisely aligned.

In physics and astronomy, "out of plane" can describe the position of an object relative to the plane of a system, such as the plane of the Earth's orbit around the Sun (the ecliptic) or the plane of a galaxy. Objects that are "out of the plane" are not within that two-dimensional surface.

In mathematics, specifically in geometry, "out of plane" could refer to a point, line, or object that does not lie within a given plane. This concept is relevant in three-dimensional geometry, where objects can exist in multiple planes or be entirely outside of any given plane.

In the context of photography or imaging, "out of plane" might refer to an object that is not within the depth of field or the focal plane of the camera, resulting in a blurry or out-of-focus image.

The term "out of plane" is often used in contrast to "in plane," which means within the specified two-dimensional surface or aligned with the designated reference plane.
