Stereo Camera
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.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Stereo Output Mode Which 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 Distance Distance between both the cameras and therefore, both eyes.
Convergence Distance Distance from the camera at which both camera perspectives converge.
Zoom The zoom of the camera. Increasing this value increases the FOV.
Field Of View Y The angle to modify the FOV with. Only functions with Use Field OF View Y enabled.
Use Field Of View Y Measure the FOV using an angle along the Y axis and the scene Aspect Ratio.
Use Field Of View Y As X Measure the FOV using an angle along the X axis instead of Y. Only functions with Use Field OF View Y enabled.
Focal Plane Distance The distance from the camera that is sharp, when utilising Depth of Field. Requires a Depth of Field Post-FX node to be used.
Focal Range The range around the focal plane that is sharp. Requires a Depth of Field Post-FX node to be used.
Focal Bluriness How blurry the focal point is. Requires a Depth of Field Post-FX node to be used.
Near Clip The closest distance that will be rendered. WARNING: Reducing this value too low can reduce the accuracy of aspects of the render.
Far Clip The 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.
Priority Change the priority of the camera. If two or more cameras have the same priority, the highest camera node in the nodegraph heirarchy is used.
Orthographic Toggle the camera to be an orthographic camera with parallel perspective.
Lock Aspect Ratio Locks the aspect ratio of the camera to a defined ratio, as opposed to those inherited from the project settings.
Aspect Ratio Defines the ratio between the cameras width and height when Lock Aspect Ratio is enabled.
Film Offset X Offsets the camera view across the directional plane of the film in the local X axis.
Film Offset Y Offsets the camera view across the directional plane of the film in the local Y axis.
