Toggle between Perspective and Orthographic camera

[SelfMade2001]

I created a toggle function that sets controls.camera to my perspectiveCamera or to my orthographicCamera. I start with my perspectiveCamera (which works fine) and switch to my orthographicCamera. I have some logic to match the position and rotation. My code works perfectly, execpt the zooming part.

I know, that the perspective camera uses dolly zoom, meaning the fov stays constant while the camera distance from the target is adjusted. Zooming out means moving the camera away. For the orthographic camera, zooming is just a number that is multiplied to the frustum.

Hence, when I do controls.camera = orthographicCamera I assume the camera-controls instance does not update the zooming method. So instead of switching to orthographic zoom it keeps adjusting the distance, which has no affect on the orthographic camera. How can I tell controls to properly adjust to the new camera?

PS: Using two camera-controls instances will not work for me, because I need to be able to switch the camera, while the user has already started dragging inside the viewport. Replacing the camera-controls instance will lead to loosing this drag.

Just want to share the fix that I figured out :D

At the end of my switchToOrthographicCamera function I do this:

controls.mouseButtons.wheel = CameraControls.ACTION.ZOOM;
controls.touches.two = CameraControls.ACTION.TOUCH_ZOOM_TRUCK;
controls.touches.three = CameraControls.ACTION.TOUCH_ZOOM_TRUCK;
controls.dollySpeed = 5; // this is optional, this makes the orthographic camera zoom faster because for me it turned out to zoom slower by default

At the end of my switchToPerspectiveCamera function I do this:

controls.mouseButtons.wheel = CameraControls.ACTION.DOLLY;
controls.touches.two = CameraControls.ACTION.TOUCH_DOLLY_TRUCK;
controls.touches.three = CameraControls.ACTION.TOUCH_DOLLY_TRUCK;
controls.dollySpeed = 1; // this is optional, this makes the orthographic camera zoom faster because for me it turned out to zoom slower by default
