问题描述
如何更改对象的大小?
我需要更改物体上的高度
i need to change height of on object
例如,我们需要更改门或窗帘的高度
For example, we need to change the height of a door or curtain
在此代码上,我的对象消失了
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);
});
}
};
以下代码会调整对象的大小,但会变得太大而无法缩放
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);
});
}
推荐答案
我找到了解决方案并为此编写了脚本
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();
};
};
对于查找碎片ID,您可以使用以下代码
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];
}
};
};
如何使用?
selection.mesh.fragIds() // [11]
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);
