Hardware Tracking Camera
Method #
Hardware Tracking Camera receives data from external camera tracking systems and currently supports the NCAM tracking system.
Camera Frustum data is received from the tracking system (Position, Rotation, Field of View) and updates the camera in the scene in real time.
Set up the NCAM receiver utilising Devices -> NCAM. Please note that access to the NCAM SDK is required for use.
The play head must be playing for the camera to update its position.
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.
- 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.
Connected NCAM Positional Data.
These properties control the core behaviours of the node.
Parameter Details
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.
Field of View The FOV of the camera. NB: Only utilised when Override FOV is enabled.
FOV Offset Adds or Subtracts X degrees from the FOV reported by the tracking system. Used to create a ‘safety’.
Use Colour Data Use the NCAM colour data.
Use Depth Data Use the NCAM depth data for compositing.
Use Distort Data Use the NCAM distort data for warping.
Override FOV Override the camera FOV.
Rotation Order Specify the rotation order of the tracking coordinate system.
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.
Overscan Amount Specify the overscan amount to ensure content fills the entire screen.
