6.1 Scene» Viewing: There are two ways of defining the view. On the one hand, theview is definable using the attributes ”Position”, ”At” and ”Up”. On the otherhand, the view can be set with the parameters ”Distance”, ”Height”, ”TurntableAngle” and ”Distance to Center”. Both methods determine the position andthe orientation of the camera. They are interdependent and influence eachother.• Use Parent Transformation: Overrides the viewing settings. Always usesthe transformation settings of the parent node in the scenegraph.Important: Now the camera is locked for mouse-navigation. The only wayto move your camera is by transforming the parent node. This feature isuseful for classic camera animation with regard to simple translation androtation.• At: Sets the coordinates for the center of interest (CoI).• Up: Sets the coordinates for the up vector to define the direction that isoriented up in the scene.• Update: Updates the render view to the entered values.• Distance: Sets the distance between the camera and the CoI.• Height: Sets the height regarding CoI and distance.• Turntable Angle: Defines the vertical angle related to the focus point.• Distance to Center: Defines the distance to the midpoint of the boundingbox of your currently selected object.» Lens Attributes:• Field of View Mode: Defines whether the angular Field of View is specifiedhorizontally or vertically.• Focal Length: Sets the focal length of the virtual objective in millimeterdepending on the given sensor height and field of view.• Sensor Presets:· 1/3.6” (4.000 w, 3.000 h)89
