BufferPoint
查阅Mars3D API

View bound to the underlying buffer data of a BufferPointCollection.

BufferPoint instances are flyweights: a single BufferPoint instance can be temporarily bound to any conceptual "point" in a BufferPointCollection, allowing very large collections to be iterated and updated with a minimal memory footprint.

Represented as one (1) position.

成员(属性)

featureId : number
engine/Source/Scene/BufferPrimitive.js 145

Feature ID associated with the primitive; not required to be unique.
继承自:

show : boolean
engine/Source/Scene/BufferPrimitive.js 157

Whether primitive is shown.
继承自:

readonly vertexCount : number
engine/Source/Scene/BufferPoint.js 92

Count of positions (vertices) in this primitive. Always 1.

方法

static Cesium.BufferPoint.clone(point, result) → BufferPoint
engine/Source/Scene/BufferPoint.js 65

Copies data from source point to result.
参数名称 类型 描述信息
point BufferPoint
result BufferPoint
返回值:

getColor(result) → Color
engine/Source/Scene/BufferPrimitive.js 201

Returns the color of primitive.
