heiser Hi!

The only way "rotate around point" is implemented at the moment is using 2 fingers on screen. You can find the relevant code, searching for this: "worldPointFingersCenter".

If you need a special method to rotate around a defined point, I'm gonna have to look into this.

Here is a method you can put in CameraBase or CameraPerspBase (only testing with perspective camera so far)

    public void RotateAround(Vector2 viewportPoint, float angle)
    {
        Quaternion twistRot = Quaternion.AngleAxis(angle, GetRotateAroundVector());
        Vector2 screenPoint = cam.ViewportToScreenPoint(viewportPoint);
        Vector3 worldPointFingersCenter = ClampInCameraBoundaries(HeightScreenDepth.Convert(screenPoint));
        Vector3 vecFingersCenterToCamera = (finalPosition - worldPointFingersCenter);
        float vecFingersCenterToCameraDistance = vecFingersCenterToCamera.magnitude * 1f;
        vecFingersCenterToCamera = vecFingersCenterToCamera.normalized * vecFingersCenterToCameraDistance;

        Vector3 targetPosition = worldPointFingersCenter + vecFingersCenterToCamera;
        Vector3 offsetFromFingerCenter = worldPointFingersCenter - worldPointFingersDelta;

        finalPosition = twistRot * (targetPosition - worldPointFingersCenter) + offsetFromFingerCenter;
        finalRotation = twistRot * finalRotation;

        currentPitch = NormalizeAngle(finalRotation.eulerAngles.x);
        currentYaw = (finalRotation.eulerAngles.y);

        Vector3 newWorldPointCameraCenter = CalculateOffset(finalPosition, finalRotation);
        Vector3 newWorldPointCameraCenterClamped = ClampInCameraBoundaries(newWorldPointCameraCenter);

        finalOffset = newWorldPointCameraCenterClamped;

        finalPosition = CalculatePosition(finalOffset, finalRotation, finalDistance);

        ApplyToCamera();
    }

Then you can call it from the CustomControlDemo.cs like so:

if (Input.GetKey(KeyCode.Space))
{
cam.RotateAround(new Vector2(0.5f, 0.75f), 30f * Time.deltaTime);
}

This will rotate the camera around the viewport point (0.5;0.75) as an example.

I'll try that out, thank you!
