LCCObject::getBounds

Gets the AABB bounding box of the LCC model scene.

Version Requirement

SDK v0.4.0+

Engine Support

Three.js / CesiumJS

API

LCCObject::getBounds(): BoundingBox

Parameters

None

Return Value

Returns a bounding box object with the following properties:

Three.js

Property	Type	Description
`min`	`{ x: number, y: number, z: number }`	Minimum point of the bounding box.
`max`	`{ x: number, y: number, z: number }`	Maximum point of the bounding box.

CesiumJS

Property	Type	Description
`min`	`{ x: number, y: number, z: number }`	Minimum point of the bounding box.
`max`	`{ x: number, y: number, z: number }`	Maximum point of the bounding box.
`origin`	`{ x: number, y: number, z: number }`	Scene origin point coordinates (WGS84 Cartesian coordinate system).

Usage Example

Three.js

const box = lccObject.getBounds();
console.log('min: ', box.min.x, box.min.y, box.min.z);
console.log('max: ', box.max.x, box.max.y, box.max.z);

CesiumJS

const box = lccObject.getBounds();
console.log('min: ', box.min.x, box.min.y, box.min.z);
console.log('max: ', box.max.x, box.max.y, box.max.z);
console.log('origin: ', box.origin.x, box.origin.y, box.origin.z);

Notes

This method must be called after the success callback of LCCRender.load() has been triggered.
In Three.js, the bounding box is based on the LCC model's local coordinate system.
In CesiumJS, for non-RTK data the bounding box is based on the LCC model's local coordinate system; for RTK data the bounding box is based on the projection coordinate system. origin uses the WGS84 Cartesian coordinate system.
