KBE3D / KBCore / Cesium / GeometryAttributes

类: GeometryAttributes

Attributes, which make up a geometry's vertices. Each property in this object corresponds to a GeometryAttribute containing the attribute's data. <p> Attributes are always stored non-interleaved in a Geometry. </p>

position: GeometryAttribute | undefined

The 3D position attribute. <p> 64-bit floating-point (for precision). 3 components per attribute. </p>

---

normal

normal: GeometryAttribute | undefined

The normal attribute (normalized), which is commonly used for lighting. <p> 32-bit floating-point. 3 components per attribute. </p>

---
