Stereo Camera

Stereo Camera

Places a camera which uses stereioscopic methods to record two prespectives into one render view.

Method #

Places a 3D Camera in the space, which records two perspective views using the Interoccular distance, focused at a point in the centre of the camera and displaced from the camera by the Convergence Distance.

The Images are then combined together, using the method described by the Stereo Output Mode.

It’s generally advised you don’t add PostFX to stereoscopic content, as many of these nodes can break the depth effect through distorting images or altering the colours.

Nodes parented to this node will generally follow the standard parent-child relationship with nodes in Notch, with a couple exceptions:

  • Most Post-FX nodes will only run when viewed through a camera when connected to the camera (although it’s still advised not to use them).
  • The Camera Focus Target controls the focus position and attributes for the camera.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Stereo Output ModeWhich kind of stereo output is used.
  • Side By Side : The Left and Right Eyes are rendered next to each other in the viewport.
  • View Left / Right : Only one eyes perspective is rendered to the viewport.
  • Anaglyph : Filters the images so that the left eye blocks out all cyan, and the right eye blocks out all red. When viewed through anaglyph glasses, the resulting image is 3D.
  • Checkerboard : The right eye is overlayed onto the left eye in a checkerboard pattern, which can be interpretted by some hardware so that the the eye views it in 3D.
Interoccular DistanceDistance between both the cameras and therefore, both eyes.
Convergence DistanceDistance from the camera at which both camera perspectives converge.
ZoomThe zoom of the camera. Increasing this value increases the FOV.
Field Of View YThe angle to modify the FOV with. Only functions with Use Field OF View Y enabled.
Use Field Of View YMeasure the FOV using an angle along the Y axis and the scene Aspect Ratio.
Use Field Of View Y As XMeasure the FOV using an angle along the X axis instead of Y. Only functions with Use Field OF View Y enabled.
Focal Plane DistanceThe distance from the camera that is sharp, when utilising Depth of Field. Requires a Depth of Field Post-FX node to be used.
Focal RangeThe range around the focal plane that is sharp. Requires a Depth of Field Post-FX node to be used.
Focal BlurinessHow blurry the focal point is. Requires a Depth of Field Post-FX node to be used.
Near ClipThe closest distance that will be rendered. WARNING: Reducing this value too low can reduce the accuracy of aspects of the render.
Far ClipThe furthest distance that will be rendered by this camera. WARNING: Increasing this value too high, without increasing the Near Clip can reduce the accuracy of aspects of the renderer. Generally best left untouched.
PriorityChange the priority of the camera. If two or more cameras have the same priority, the highest camera node in the nodegraph heirarchy is used.
OrthographicToggle the camera to be an orthographic camera with parallel perspective.
Lock Aspect RatioLocks the aspect ratio of the camera to a defined ratio, as opposed to those inherited from the project settings.
Aspect RatioDefines the ratio between the cameras width and height when Lock Aspect Ratio is enabled.
Film Offset XOffsets the camera view across the directional plane of the film in the local X axis.
Film Offset YOffsets the camera view across the directional plane of the film in the local Y axis.

Included ObjectsSelect nodes will be included in the final rendering from this camera. Once a node is connected, all unconnected nodes will be treated as excluded.3D Object
Excluded ObjectsSelect objects to be ignored by this camera. These objects will not be rendered, but will otherwise be generated and impact performance. Once a node is connected, all unconnected nodes will be treated as included.3D Object
Transform ModifierApply the transforms of another node to this node.Null
Target NodeModifiy the rotations of the node to always direct the z axis towards the input.Null
Local Transform OverrideApply the transforms of another node to this node, relative to its parent.Null
