flat · commonsurfacegeometry
A surface in which space is uniform across all parts and lies even with a plane, having no variation in height.
Examples
- The surface of Lake Pontchartrain spans 632 square kilometers with less than 1 meter variation in elevation across its extent. geography
- The silicon wafer used in Intel's 14nm fabrication process maintains a flatness within 0.1 micrometers across its 300mm diameter. engineering
- The floor of the Sistine Chapel's nave was laid to be flat within 2mm over 40 meters, as measured during the 1980 restoration. architecture
Emergence
through: Space.extent and pattern.regularity establish a uniform expanse, while boundary.limit determines where it ends, part.relation connects positions on surface.exterior to a shared plane, across.spatial ensures continuity from side to side, and even.numerical guarantees uniform alignment with a plane.
- uniform continuity
- planar alignment
- height invariance
