# GeometryAttributes

#### new Cesium.GeometryAttributes()
engine/Source/Core/GeometryAttributes.js 13

Attributes, which make up a geometry's vertices. Each property in this object corresponds to a `GeometryAttribute` containing the attribute's data.

Attributes are always stored non-interleaved in a Geometry.
