Zoom To Mouse Position Enables you to control exactly what point in the space your view zooms in on
when you rotate the mouse wheel, by positioning the mouse where you want to zoom.
Rotate Around Selection Causes the view to rotate around the median point between selected elements.
Global Pivot Causes the selected pivot to be fixed over all 3D viewport windows. If this option is not selec-
ted, each 3D viewport can use a different pivot.
Camera Parent Lock Causes objects above a camera in a parent hierarchy to be affected when the Lock
Camera To View feature is activated. This can be useful when the camera is being controlled by camera rigs,
because it enables the entire camera rig to be controlled by camera locking.
Auto Perspective Causes the view to enter Perspective view whenever it is rotated out of Front, Side, or Top
view and to enter Orthogonal view when it enters those views by means of hot keys on the number pad.
Smooth View Sets a time interval in milliseconds for an animated transition between number-pad views.
Rotation Angle Sets the degree of rotation used by the 2, 4, 6, and 8 keys on the number pad to rotate the
view incrementally.
Minimum Grid Spacing Determines the density of grids in terms of pixel spacing between grid lines for 2D
viewports such as the Timeline, the Graph Editor, and the Dope Sheet.
TimeCode Sty Gives options for the writing style for time codes.
The options available in the third column of the Interface area are as follows:
Manipulator Toggles the 3D manipulator on and off. The Size, Handle Size, and Hotspot values determine
how big the manipulator is, how big its handles are, and how big the area is where it is sensitive to being
selected.
Open On Mouse Over Enables menus to open automatically when the mouse is held over them, without
clicking. The numerical values for this option determine how long the mouse must be held over the main
menu or submenus before the menus open.
Show Splash Determines whether the Blender splash screen is displayed on startup.
