Restricting panning in OrbitControls with Three.js

Is there a way in Three.js to restrict the user from panning too far left, right, up, or down when using OrbitControls? I want to prevent panning so far that objects in the scene become invisible.

Answer №1

The latest update to OrbitControls.js now includes a feature where the camera's position is adjusted based on panning movements. You can view the specific code changes here.

If you need to set boundaries for panning, you can easily implement this by checking if the new camera position falls within these boundaries before updating it:

var newX = this.target.x + pan.x;
var newY = this.target.y + pan.y;
if (newX <= this.maxXPan && newX >= this.minXPan 
        && newY <= this.maxYPan && newY >= this.minYPan) {
    this.target.add( pan );
}
