Autodesk Forge Viewer缩放到边界框 [英] Autodesk forge viewer zooming to bounding box

问题描述

我有一个如下的边界框对象:

I have a bounding box object as below:

bb = {
  "min": {
    "x": -6.637446403503418,
    "y": -19.579801559448242,
    "z": -0.22575747966766357
  },
  "max": {
    "x": 10.237555503845215,
    "y": 19.15947914123535,
    "z": 9.774243354797363
  }
}

我想缩放到此边界框，并以相机为中心.

I want to zoom to this bounding box and make camera as centre.

推荐答案

您只需调用 viewer.navigation.fitBounds(立即，界限)即可.

• 第一个参数 immediate (立即)表示相机位置将如果将即时设置为假，则为新位置设置动画.
• 第二个参数 bounds 表示要适合的边界框.

• The first argument, immediate, means that camera position will animate to the new location if immediate is set as false.
• The second argument, bounds, stands for the bounding box to fit.

记住要将您的边界框转换为 THREE.Box3对象.

Remember to convert your bounding box to THREE.Box3 object.
