Near/Far Clip
The clipping plane is used to limit what geometry in a scene is rendered based on the object’s
distance from the camera’s focal point. This is useful for ensuring that objects that are extremely
close to the camera are not rendered and for optimizing a render to exclude objects that are
too far away to be useful in the final rendering.
The default perspective camera ignores this setting unless the Adaptively Adjust Near/Far Clip
checkbox control below is disabled.
The values are expressed in units, so a far clipping plane of 20 means that any objects more
than 20 units from the camera are invisible to the camera. A near clipping plane of 0.1 means
that any objects closer than 0.1 units are also invisible.
Adaptively Adjust Near/Far Clip
When selected, the Renderer automatically adjusts the camera’s near/far clipping plane to
match the extents of the scene. This setting overrides the values of the Near and Far clip range
control described above. This option is not available for orthographic cameras.
Viewing Volume Size
The Viewing Volume Size control appears only when the Projection Type is set to Orthographic.
It determines the size of the box that makes up the camera’s field of view. The Z distance of an
orthographic camera from the objects it sees does not affect the scale of those objects, only
the viewing size does.
NOTE: A smaller range between the near and far clipping plane allows greater
accuracy in all depth calculations. If a scene begins to render strange artifacts on
distant objects, try increasing the distance for the near clip plane. Use the vertical
aperture size to get the vertical angle of view and the horizontal aperture size to get
the horizontal angle of view.
Plane of Focus (for Depth of Field)
This value is used by the OpenGL renderer to calculate depth of field. It defines the distance to
a virtual target in front of the camera.
Stereo Method
This control allows you to adjust your stereoscopic method to your preferred working model.
Toe In
Both cameras point at a single focal point. Though the result is stereoscopic, the vertical
parallax introduced by this method can cause discomfort by the audience.
Off Axis
Often regarded as the correct way to create stereo pairs, this is the default method in Fusion.
Off Axis introduces no vertical parallax, thus creating less stressful stereo images.
Parallel
The cameras are shifted parallel to each other. Since this is a purely parallel shift, there is no
Convergence Distance control. Parallel introduces no vertical parallax, thus creating less
stressful stereo images.
