Returns the requested section planes of the specified bounding box.

## Usage

```javascript
const boundingBox = {
  max: {
    x: 10,
    y: 10,
    z: 0
  },
  min: {
    x: 0,
    y: 0,
    z: 0
  }
};
const objectIds = ["object-1", "object-2"];
const planeNames = ["left", "right"];

const planes = viewer3d.calculateSectionPlanesForBoundingBox(boundingBox, planeNames);
```

- `back`

## Return Value

List of planes.

| **Type**       |
| -------------- |
| Array\[Object] |

**Plane**

| **Name**    | **Type**     | **Description**        |
| ----------- | ------------ | ---------------------- |
| `location`  | [Vector3](#) | Location of the plane  |
| `direction` | [Vector3](#) | Direction of the plane |

### Example

      z: 0
    }
  },
  {
    location: {
      x: 10,
      y: 10,
      z: 0
    },
    direction: {
      x: 1,
      y: 0,
      z: 0
    }
  }
];
