添加剖切面
Examples
js
//六个标准方向(写的方向就是对应要剖切的方向,保留的是相反的方向,如Vector3(0, -1, 0)剖切方向为上)
//Vector3(0, -1, 0))//上
//Vector3(0, 1, 0))//下
//Vector3(1, 0, 0)//西
//Vector3(-1, 0, 0))//东
//Vector3(0, 0, 1)//北
//Vector3(0, 0, -1)//南
let sceManager =await cloud.getSceneManager();
var rootNode = await sceManager.getRootNode3D();//获取根节点
await cloud.getSectioningManager()
const dir=new Vector3(1,0,0);
const pos=new Vector3(1,0,1);
const state: NodeState = {
color: '0xFF0000',
opacity: 100,
show: true,
}
let obj= await cloud.sectioningManager.addPlaneSection(pos,rootNode!,dir,state)//六个标准方向(写的方向就是对应要剖切的方向,保留的是相反的方向,如Vector3(0, -1, 0)剖切方向为上)

addBoxSection
▸ addBoxSection(transform, operationNode, state): Promise<SectionObject>
Details

Examples
js
await cloud.getSectioningManager()
let sceManager =await cloud.getSceneManager();
var rootNode = await sceManager.getRootNode3D();//获取根节点
const ope = await sceManager.getNodeOperator()
const box = await ope.getLocalBox(rootNode!)
box.expandByScalar(1.125) //推荐参数 1.125(对剖切盒放大)
const trans: Transform = box.boxToTransform()
const state: NodeState = {
color: '0xFF0000',
opacity: 100,
show: true,
}
let obj= await cloud.sectioningManager.addBoxSection(trans,rootNode!,state);await cloud.getSectioningManager()
let sceManager =await cloud.getSceneManager();
var rootNode = await sceManager.getRootNode3D();//获取根节点
const ope = await sceManager.getNodeOperator()
const box = await ope.getLocalBox(rootNode!)
box.expandByScalar(1.125) //推荐参数 1.125(对剖切盒放大)
const trans: Transform = box.boxToTransform()
const state: NodeState = {
color: '0xFF0000',
opacity: 100,
show: true,
}
let obj= await cloud.sectioningManager.addBoxSection(trans,rootNode!,state);Parameters
