可以的，你可以這樣來達成：
依 Y 軸旋轉 180 度(以下為ES2015的代碼示例)：
class RotateExt extends Autodesk.Viewing.Extension {
constructor( viewer, options ) {
super();
}
load() {
viewer.addEventListener( Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionChanged );
return true;
}
unload() {
viewer.removeEventListener( Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionChanged );
return true;
}
/**!
* 關鍵函數
*/
onSelectionChanged = ( event ) => {
const quaternion = new THREE.Quaternion();
// 設置旋轉量 - 依 Y 軸旋轉構件 180 度
quaternion.setFromAxisAngle( new THREE.Vector3( 0,1,0 ), Math.PI );
const model = event.model;
const fragIdsArray = event.fragIdsArray;
fragIdsArray.forEach( ( fragId, idx ) => {
const fragProxy = this.viewer.impl.getFragmentProxy( model, fragId );
fragProxy.getAnimTransform();
const position = new THREE.Vector3( fragProxy.position.x, fragProxy.position.y, fragProxy.position.z );
position.applyQuaternion( quaternion );
fragProxy.position = position;
fragProxy.quaternion.multiplyQuaternions( quaternion, fragProxy.quaternion );
if( idx === 0 ) {
const euler = new THREE.Euler();
euler.setFromQuaternion( fragProxy.quaternion, 0 );
}
fragProxy.updateAnimTransform();
});
this.viewer.impl.sceneUpdated( true );
};
}
Autodesk.Viewing.theExtensionManager.registerExtension( 'Autodesk.ADN.Viewing.Extension.RotateTool', RotateExt );
沿X軸移動 -100 單位(以下為ES2015的代碼示例)：
class TranslateExt extends Autodesk.Viewing.Extension {
constructor( viewer, options ) {
super();
}
load() {
viewer.addEventListener( Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionChanged );
return true;
}
unload() {
viewer.removeEventListener( Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionChanged );
return true;
}
/**!
* 關鍵函數
*/
onSelectionChanged = ( event ) => {
// 設置移動量 - 向 X 軸移動 -100 單位
const offset = new THREE.Vector3( -100, 0 , 0 );
const model = event.model;
const fragIdsArray = event.fragIdsArray;
fragIdsArray.forEach( ( fragId, idx ) => {
const fragProxy = this.viewer.impl.getFragmentProxy( model, fragId );
fragProxy.getAnimTransform();
const position = new THREE.Vector3(
fragProxy.position.x + offset.x,
fragProxy.position.y + offset.y,
fragProxy.position.z + offset.z
);
fragProxy.position = position;
fragProxy.updateAnimTransform();
});
this.viewer.impl.sceneUpdated( true );
};
}
Autodesk.Viewing.theExtensionManager.registerExtension( 'Autodesk.ADN.Viewing.Extension.TranslateTool', TranslateExt );
