How to a plane always keeps full screen that unaffected by mouse scrolling

.I create a plane , when I scroll mouse ,I would like this plane always keeps same size. It likes cesuim’s ground which keeps full screen that unaffected by mouse scrolling.

Do you want to orbit around the plane using OrbitControls? If so, you could set the min/max distance for scrolling to equal your desired distance. Or you might even be able to disable scrolling.
