surfaceskimming

Surface skimming is the informal term for techniques and analyses that concentrate on data from, or manipulations performed at, a thin region adjacent to a surface boundary. It often implies sampling within a shallow depth or focusing attention on the boundary while de-emphasizing the bulk interior.

In computer graphics and geometry processing, surface skimming refers to methods that sample the surface neighborhood to estimate geometric properties such as normals and curvature, or to guide surface reconstruction and mesh processing. The goal is to capture details of the surface itself without requiring full-volume information, enabling efficient rendering and modeling workflows.

In materials science and surface science, the concept describes approaches for characterizing surface composition, roughness, coatings, or thin films by shallow-depth measurements or signals originating near the interface. Techniques framed as surface skimming aim to reveal boundary behavior while reducing influence from deeper material layers.

In fluid dynamics and related fields, surface skimming is used informally to describe studies of boundary-layer phenomena, where the focus is on flows constrained to or interacting with a surface. This includes investigations of drag, shear stresses, and near-surface turbulence as distinct from bulk fluid behavior.

The term remains informal and multidisciplinary, with no single standardized definition. It typically signals a preference for boundary-focused data, analysis, or modeling that emphasizes the interface between two phases or materials. Related concepts include boundary layer analysis, depth profiling, and surface reconstruction.
