目标实时定位

GPS、蓝牙信标等数据源的位置实时定位

参数

new MMSDT.GPSpositioning(parameters, callback)

parameters: 参数设置

var parameters = {
model: 'models/car.gltf', //需要定位的车辆三维模型
scale: 1.3, //三维模型缩放大小
rotation: -Math.PI*0.5, //车头向前，旋转偏移
icon: 'textures/gps.png', //显示图标
color: 0x00ff00, //图标默认颜色
height: 10, //图标相对高度
size: 1.2, //图标缩放大小
id: ['QR9526','EF9527','MG9528'], //数组，车辆ID号
}

callback: 回调函数，定位车辆加载完成
