When I add a LineWidget to the VTK model, the first time I click the mouse, an exception occurs:
2. When I add multiple LineWidgets, the rotation of the vtk model will lag
3.I use 25.14.0,the UI screenshot is in attachment Today
my code:
document.body.addEventListener(“click”, this.bodyClick, false);
bodyClick(e) {
console.log(“bodyClick”,e);
const position = {
x: e.clientX,
y: e.clientY,
z: 0.0,
};
// console.log(position);
this.markRenderer(position);
},
//vtkLineWidget
console.log('markRenderer,new vtkLineWidget');
const widgetManager = vtkWidgetManager.newInstance();
widgetManager.setRenderer(renderer);
let widget = vtkLineWidget.newInstance();
let lineHandle = widgetManager.addWidget(widget);
let widgetState = lineHandle.getWidgetState();
const subState = lineHandle.getWidgetState().getPositionOnLine();
subState.setPosOnLine(1.05);
lineHandle.setText(""+data.cell);
widgetState.setLineThickness(1);
widgetState.getMoveHandle().setScale1(14);
lineHandle.getWidgetState().getHandle1().setVisible(false);
lineHandle.getWidgetState().getHandle2().setVisible(false);
lineHandle.getInteractor().render();
// widgetState.onModified(() => {
// console.log("vtkLineWidget 改变:");
// const subState = lineHandle.getWidgetState().getPositionOnLine();
// subState.setPosOnLine(1.0);
// lineHandle.setText(""+data.cell);
// // renderWindow.render();
// });
widget.getManipulator().setUserOrigin(pickPoint);
this.setupSVG2(renderer,lineHandle,point,point2);
widgetManager.grabFocus(widget);
