示例： Example:
const collection = new BufferPointCollection({primitiveCountMax: 1024});
const point = new BufferPoint();
const material = new BufferPointMaterial({color: Color.WHITE});
// Create a new point, temporarily bound to 'point' local variable.
collection.add({
position: new Cartesian3(0.0, 0.0, 0.0),
material
}, point);
// Iterate over all points in collection, temporarily binding 'point'
// local variable to each, and updating point material.
for (let i = 0; i < collection.primitiveCount; i++) {
collection.get(i, point);
point.setMaterial(material);
}

方法 Methods
使用指定的选项将新点添加到集合中。一个
Adds a new point to the collection, with the specified options. A
BufferPoint 实例链接到新点，如果给定则使用“结果”参数，如果没有则使用新实例。对于重复调用，最好重用单个 BufferPoint 实例，而不是在每次调用时分配一个新实例。
instance is linked to the new point, using the 'result' argument if given, or a new instance if not. For repeated calls, prefer to reuse a single BufferPoint instance rather than allocating a new instance on each call.
