OnePlane

Oneplane, sometimes written as oneplane or OnePlane, is a term encountered in multiple disciplines to denote a concept centered on a single reference plane. There is no single, universal definition, and the exact meaning is typically specialized to the field or even to a particular author or vendor.

In geometry and computer graphics, oneplane commonly describes constructs defined with respect to one planar reference. For example, plane fitting, projection, or rendering pipelines may be described as operating on a “one-plane” model when all calculations assume a single, fixed plane before applying transformations. The term is largely descriptive rather than a formal mathematical category.

In optical engineering and lens design contexts, "one-plane" appears in discussions of design strategies or manufacturing constraints that emphasize a single primary plane for alignment or aberration control. Because equipment and literature do not standardize the term, its precise interpretation depends on the source.

In software and data processing, some projects use "oneplane" as a project name or module label associated with plane-based processing, such as planar segmentation, plane detection in point clouds, or planar algebra tasks. In these cases, the intended meaning is likewise dependent on the project documentation.

See also plane, projection, plane fitting, planar, and multi-plane concepts. Due to vary definitions, readers should consult the context where the term appears to determine the exact meaning.
