float-array-3

schema/elements/float-array-3/1.0.1/float-array-3.schema.json

Array of 64-bit floating-point values with three values per row (N×3). Extends float-array-md with a fixed width of 3. The most widely used element — stores 3D vertex coordinates, direction vectors, and RGB colour data across geometry and attribute components.

When the three columns hold coordinates, their order follows the axis order declared in the object's coordinate_reference_system rather than a fixed easting/northing/elevation ordering. See Coordinate reference systems and axis order.

See also: float-array-md (base type), float-array-1, float-array-2, float-array-6 (other widths).
