# Stereo Object Axis Settings

Use the Axis tab of the Stereo Object menu to position, rotate, scale, and shear an axis, as well as adjust the convergence, parenting, and autoscaling of stereo objects.

The Axis controls are described as follows.

X Position field
  Displays the position of the X axis. Editable.

Y Position field
  Displays the position of the Y axis. Editable.

Z Position field
  Displays the position of the Z axis. Editable.

Motion Path button
  Enable to animate the position of the axis using a spline drawn in the scene. Disable to animate the position of the axis using explicit animation. See Creating a Motion Path.

X Rotation field
  Displays the rotation of the X axis. Editable.

Y Rotation field
  Displays the rotation of the Y axis. Editable.

Z Rotation field
  Displays the rotation of the Z axis. Editable.

X Scale field
  Displays the scale of the X axis. Editable.

Y Scale field
  Displays the scale of the Y axis. Editable.

Z Scale field
  Displays the scale of the Z axis. Editable.

Proportional button
  Enable to change the fields proportionally.

Autoscale box
  Select whether to autoscale when settings are changed relative to the camera.

  Select: | To:
  --- | ---
  Auto Off | Not use autoscaling on the image.
  Auto Z | Link the Position Z parameter with Convergence. This allows you to see how a change in the Convergence value makes the object appear to move closer or farther from the camera. This preserves the same visual aspect while scaling the textures up or down accordingly. NoteThe result camera must be set to the stereo camera.
  AutoScale | Change the left and right texture parameters when the Position Z or a Scale parameter is changed. When you create a stereo object, it is automatically oriented towards the camera and automatically scales. That is, the apparent size of the images scale to compensate when you move the stereo object along the Z axis. If you move a stereo object away from the camera, it grows, and vice versa. NoteThe result camera must be set to the stereo camera.

X Centre field
  Displays the centre of the X axis. Editable.

Y Centre field
  Displays the centre of the Y axis. Editable.

Z Centre field
  Displays the centre of the Z axis. Editable.

Convergence field
  Displays the equal amount of convergence in opposite directions horizontally, between left and right images. Positive values make the image appear farther from the camera. Editable.

Parent To button
  Enable to associate a stereo object with the camera selected in the Parent Camera box. Enabled by default to force the stereo object to face the FBX camera at all times when the camera is moved around.

Parent Camera box
  Select which camera in the scene is associated with the stereo object.
