请问有办法在选中一个构件后让他移动或旋转吗?例如选中后依某个轴向旋转一角度,或者是选中后让构件移动到其他位置?
学习是最好的投资!
可以的,你可以这样来达成:
依 Y 轴旋转 180 度(以下为ES2015的代码示例):
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; } /**! * 关键函数 */ onSelectionChanged = ( event ) => { const quaternion = new THREE.Quaternion(); // 设置旋转量 - 依 Y 轴旋转构件 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轴移动 -100 单位(以下为ES2015的代码示例):
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; } /**! * 关键函数 */ onSelectionChanged = ( event ) => { // 设置移动量 - 向 X 轴移动 -100 单位 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 );
