6.1 Scene• Field of View: Sets the field of view angle of the camera, measured in degrees.You can switch between horizontally and vertically defined FOV via LensAttributes » Field of View Mode. The Field of View parameter is directlyconnected to the focal length parameter.» Viewing: There are two ways of defining the view. On the one hand, the view isdefinable using the attributes ”Position”, ”At” and ”Up”. On the other hand, theview can be set with the parameters ”Distance”, ”Height”, ”Turntable Angle” and”Distance to Center”. Both methods determine the position and the orientationof the camera. They are interdependent and influence each other.• 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 way to moveyour camera is by transforming the parent node. This feature is useful for classiccamera animation with regard to simple translation and rotation.• 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 millimeter dependingon the given sensor height and field of view.• Sensor Presets:91
