该业务包严格对应 MineMap 的三维组件主入口 map.addSceneComponent()。
源码层面的稳定事实：
3d-model 走 SceneModel3d-tiles 走 SceneTilesetaddSource(type="3d-tiles")、addLayer(type="3d-tiles") 已被明确标注为废弃提示因此，新业务代码应统一采用：
Map 初始化load 或 style.load 后添加三维组件getSceneComponent() 管理对象生命周期3d-model适用：
matrix、局部动画、最小屏幕像素尺寸时优先能力：
minimumPixelSizeactiveAnimationaccurateBoundingdistanceDisplayConditionpositions/rotations/scales/instanceNames 实例化allowWaterReflect / allowWaterRefract3d-tiles适用：

positions 必填rotations/scales/colors/shows/instanceNames 选填3d-modelaccurateBounding=true：可解决动画引起的包围盒不准，但会增加运行时成本minimumPixelSize：能保住远景可见性，但会改变真实尺度感知activeAnimation：只针对 glTF 自带动画，不等于场景轨迹动画SceneTileset Professional GuidemaximumScreenSpaceError 越小越清晰，网络与内存压力越高8 ~ 1612 ~ 206 ~ 12maximumMemoryUsage 是核心控制项SceneTileset 中为 256 MB 级别逻辑支持：

BALANCEDEFFECTIVENESS_FIRSTEFFICIENCY_FIRSTskipLevelOfDetailimmediatelyLoadDesiredLevelOfDetail原因：源码注释已明确提示，这类参数虽然可能提高某些命中率，但会带来模糊或移动时加载变慢的问题。
如果一次添加多份 urls：
geoBoundsOptions.index：指定飞向哪一份geoBoundsOptions.combine：合并边界后飞行该逻辑直接影响 flyTo/jumpTo/easeTo 针对 tileset 的定位结果。
