Optimizing Attributes of the 3D Camera
Here are some general guidelines for tweaking the stereo attributes of the 3D camera:
Many parameters are relative to each other, and can be scaled and changed upon import using the Auto
Fit in Scene or FBX Unit to Pixels settings.
Tweak the Interaxial Separation to move the cameras closer to or farther away from one another.
NOTE You should re-adjust your Interaxial Separation if you change your output device, since the settings for
one display method may differ from another.
Increase the Zero Parallax to move objects further away from the camera. The 3D effect becomes less
pronounced in this case. Decrease your Zero Parallax to move objects closer to the camera. You can see
more depth if you do this.
The stereoscopic effect is the most realistic when the Zero Parallax Plane is in between the two objects.
You may need to re-adjust your camera attributes if you change the resolution of your output device.
You can also increase the Far Clip Plane to increase the depth of the camera.
In Anaglyph viewing mode, the red/cyan colors for objects are swapped depending on whether they are
behind or in front of the parallax plane. For objects behind the zero parallax plane, they appear in
cyan/red. For objects in front of the zero parallax plane, they appear in red/cyan.
Working with the Frustum
The volume of space viewed by the camera is called the frustum. The frustum is, in effect, a viewing pyramid.
The camera is located at the apex of the pyramid, and the far clipping plane forms the base. The pyramid
may be truncated by the near clipping plane. The point of interest, or aim, is the target at the center of the
cameras view.
