Camera behavior after update to version 1.70

Yeah, that’s exactly right. The distance can be increased but it’s not part of the public API at the moment.

var cameraController = viewer.scene.screenSpaceCameraController;
cameraController._maximumUndergroundPickDistance = 20000.0; // default is 10000.0

            // Constants, Make any of these public?
            this._zoomFactor = 5.0;
            this._rotateFactor = undefined;
            this._rotateRateRangeAdjustment = undefined;
            this._maximumRotateRate = 1.77;
            this._minimumRotateRate = 1.0 / 5000.0;
            this._minimumZoomRate = 20.0;
            this._maximumZoomRate = 5906376272000.0; // distance from the Sun to Pluto in meters.
            this._minimumUndergroundPickDistance = 2000.0;
            this._maximumUndergroundPickDistance = 10000.0;
          }
          
          function decay(time, coefficient) {
            if (time < 0) {
              return 0.0;
            }
          
            var tau = (1.0 - coefficient) * 25.0;
            return Math.exp(-tau * time);
          }
