我正在使用以下代码使用Viewer3D.loadDocumentNode(API v7)加载其他模型,效果很好。但是我有两个问题:
Autodesk.Viewing.Document.load(`urn:${myURN}`, (doc) => {
var viewables = doc.getRoot().getDefaultGeometry();
viewer.loadDocumentNode(doc, viewables,{
placementTransform: (new THREE.Matrix4()).setPosition({x:0,y:0,z:0}),
keepCurrentModels: true,
globalOffset: {x:0,y:0,z:0}
})
.then( onLoadFinished );
});
第一期:加载汇总模型后,不再触发我等待SELECTION_CHANGED_EVENT的扩展程序。
load() {
this.onSelectionBinded = this.onSelectionEvent.bind(this);
this.viewer.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionBinded);
console.log('ReactToEvents has been loaded');
return true;
}
示例来自https://forge.autodesk.com/en/docs/viewer/v7/developers_guide/viewer_basics/events/
第二个问题:解析所选元素的另一个扩展未考虑聚合模型中的所选元素(选择数= 0)
onToolbarCreated() {
// Create a new toolbar group if it doesn't exist
this._group = this.viewer.toolbar.getControl('allMyAwesomeExtensionsToolbar');
if (!this._group) {
this._group = new Autodesk.Viewing.UI.ControlGroup('allMyAwesomeExtensionsToolbar');
this.viewer.toolbar.addControl(this._group);
}
// Add a new button to the toolbar group
this._button = new Autodesk.Viewing.UI.Button('handleSelectionExtensionButton');
this._button.onClick = (ev) => {
// Get current selection
const selection = this.viewer.getSelection();
this.viewer.clearSelection();
// Anything selected?
console.log("Clicked handleSelectionExtensionButton: ", selection.length);
if (selection.length > 0) { ... }
}
}
出于某种原因this.viewer.getSelection()
;忽略来自loadDocumentNode()
的内容。
我尝试卸载/重新加载扩展,但仍然无法正常工作。
任何帮助,不胜感激!
答案 0 :(得分:1)
稍后添加了对加载多个模型的支持,并且为了防止破坏向后兼容性,开发人员添加了应在多模型方案中使用的新API和事件名称。查找其中带有“聚合”字样的方法和事件,例如getAggregateSelection,Autodesk.Viewing.AGGREGATE_SELECTION_CHANGED_EVENT
或Autodesk.Viewing.AGGREGATE_FIT_TO_VIEW_EVENT
。
