如何调整对象大小 - Autodesk Forge Viewer [英] How to resize on object - Autodesk Forge Viewer

问题描述

如何更改对象的大小??

我需要改变对象的高度

例如，我们需要改变门或窗帘的高度

<块引用>

在这段代码中，我的对象消失了

let change = function () {const 查看器 = oViewer;const 模型 = viewer.model;常量片段 = [123,361,];for(让我在碎片中){让 fragId = frags[i];//获取带有片段 ID 的网格让mesh = viewer.impl.getRenderProxy(model, fragId);//选择 ID让 dbId = 1280;//viewer.getSelection()[0]model.getData().instanceTree.enumNodeFragments(dbId, fragId => {网格.scale.x += 0.5;//网格.scale.y = 5;//网格.scale.z = 5;model.getFragmentList().setMesh(fragId, mesh, true);viewer.impl.invalidate(true);});}};

<块引用>

以下代码调整对象大小但变得太大且无法缩放

const viewer = oViewer;const 模型 = viewer.model;viewer.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT，onSelectedCallback)；函数 onSelectedCallback(事件){const fragId = event.fragIdsArray[0];if (typeof fragId == 'undefined') {return;}const fragIdsArray = (Array.isArray(fragId) ? fragId : [fragId]);fragIdsArray.forEach(function (subFragId) {让mesh = viewer.impl.getRenderProxy(model, subFragId).clone();网格.scale.y += 0.2;网格.scale.x += 0.2;网格.scale.z += 0.2;model.getFragmentList().setMesh(subFragId, mesh, true);viewer.impl.invalidate(true);});}

解决方案

我找到了解决方案并为其编写了脚本

let transform = new function () {让_self = this;this.fragId = null;this.proxy = null;this.viewer = oViewer;this.model = this.viewer.model;this.setFragId = 函数(fragId){this.fragId = fragId;this.proxy = this.viewer.impl.getFragmentProxy(this.model, this.fragId);this.proxy.getAnimTransform();};this.update = 函数(){this.proxy.updateAnimTransform();this.viewer.impl.sceneUpdated(true);};this.scaleX = 函数(数量){this.proxy.scale.x = num + 1;this.update();};this.scaleY = 函数(数量){this.proxy.scale.y = num + 1;this.update();};this.scaleZ = 函数(数量){this.proxy.scale.z = num + 1;this.update();};this.positionX = 函数(数量){this.proxy.position.x = num;this.update();};this.positionY = 函数(数量){this.proxy.position.y = num;this.update();};this.positionZ = 函数(数量){this.proxy.position.z = num;this.update();};};

<块引用>

要查找碎片 ID，您可以使用以下代码

let selection = new function () {this.viewer = oViewer;让_self = this;this.ids = 函数 () {返回 this.viewer.getSelection();};this.count = 函数 () {返回 this.viewer.getSelectionCount();};//网格对象this.mesh = 新函数 () {this.all = 函数 () {if (_self.count() === 0) return {};让网格 = _self.viewer.impl.selectionMeshes;让输出 = [];for(让索引在网格中){输出.推(网格[索引])；}返回输出；};this.fragIds = function(){让网格 = this.all();让 ids = [];网格.forEach(功能(网格){ids.push(mesh.fragId);});返回 ID；};this.first = 函数 () {返回 this.all()[0];};this.last = 函数 () {返回 this.all().reverse()[0];}};};

如何使用?

用鼠标选择你的元素

打开浏览器控制台

输入 selection.mesh.fragIds()//[11]

输入transform.setFragId(11)

现在您可以更改比例和位置:)

transform.scaleX(number);transform.scaleY(number);transform.scaleZ(number);transform.positionX(number);transform.positionY(number);transform.positionZ(number);

How can i change size of on object ??

i need to change height of on object

For example, we need to change the height of a door or curtain

on this code my object disappears

let change = function () {

    const viewer = oViewer;
    const model = viewer.model;

    const frags = [
        123,
        361,
    ];

    for(let i in frags){

        let fragId = frags[i];

        // Get mesh with frag id
        let mesh = viewer.impl.getRenderProxy(model, fragId);

        // Selection ID
        let dbId = 1280; // viewer.getSelection()[0]

        model.getData().instanceTree.enumNodeFragments(dbId, fragId => {
            mesh.scale.x += 0.5;
            // mesh.scale.y = 5;
            // mesh.scale.z = 5;

            model.getFragmentList().setMesh(fragId, mesh, true);
            viewer.impl.invalidate(true);
        });
    }
};

The following code resizes objects but becomes too large and cannot be scaled

const viewer = oViewer;
const model = viewer.model;

viewer.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, onSelectedCallback);

function onSelectedCallback(event) {

    const fragId = event.fragIdsArray[0];

    if (typeof fragId == 'undefined') {return;}

    const fragIdsArray = (Array.isArray(fragId) ? fragId : [fragId]);

    fragIdsArray.forEach(function (subFragId) {

        let mesh = viewer.impl.getRenderProxy(model, subFragId).clone();

        mesh.scale.y += 0.2;
        mesh.scale.x += 0.2;
        mesh.scale.z += 0.2;

        model.getFragmentList().setMesh(subFragId, mesh, true);
        viewer.impl.invalidate(true);
    });
}

解决方案

I found the solution and wrote the script for it

let transform = new function () {

    let _self = this;

    this.fragId = null;
    this.proxy = null;
    this.viewer = oViewer;
    this.model = this.viewer.model;

    this.setFragId = function (fragId) {
        this.fragId = fragId;
        this.proxy = this.viewer.impl.getFragmentProxy(this.model, this.fragId);
        this.proxy.getAnimTransform();
    };

    this.update = function(){
        this.proxy.updateAnimTransform();
        this.viewer.impl.sceneUpdated(true);
    };

    this.scaleX = function (num) {
        this.proxy.scale.x = num + 1;
        this.update();
    };

    this.scaleY = function (num) {
        this.proxy.scale.y = num + 1;
        this.update();
    };

    this.scaleZ = function (num) {
        this.proxy.scale.z = num + 1;
        this.update();
    };

    this.positionX = function (num) {
        this.proxy.position.x = num;
        this.update();
    };

    this.positionY = function (num) {
        this.proxy.position.y = num;
        this.update();
    };

    this.positionZ = function (num) {
        this.proxy.position.z = num;
        this.update();
    };

};

for find frag Ids you can use follow code

let selection = new function () {

    this.viewer = oViewer;

    let _self = this;

    this.ids = function () {
        return this.viewer.getSelection();
    };

    this.count = function () {
        return this.viewer.getSelectionCount();
    };

    // Mesh Object
    this.mesh = new function () {
        this.all = function () {
            if (_self.count() === 0) return {};

            let meshes = _self.viewer.impl.selectionMeshes;
            let output = [];

            for (let index in meshes) {
                output.push(meshes[index]);
            }

            return output;
        };

        this.fragIds = function(){
            let meshes = this.all();
            let ids = [];
            meshes.forEach(function(mesh){
                ids.push(mesh.fragId);
            });
            return ids;
        };

        this.first = function () {
            return this.all()[0];
        };

        this.last = function () {
            return this.all().reverse()[0];
        }
    };

};

How to use ?

Select your element with mouse

Open browser console

Type selection.mesh.fragIds() // [11]

Type transform.setFragId(11)

Now You Can Change Scale and position :)

transform.scaleX(number);

transform.scaleY(number);

transform.scaleZ(number);


transform.positionX(number);

transform.positionY(number);

transform.positionZ(number);
