Example Pipeline
Preliminary Preparation

Prepare your scene, launch it via Reality Hub Launcher module.
Drag & drop the
UE5
processing node into Nodegraph canvas.Create two Reality Cameras. See Actor Spawning.
Add
AJAIn
andAJAOut
nodes, select your devices and outputs based on your setup.Create your Track node. (In our example it will be the
Xync
Node)
Modifying Curve XR Node

Add
Curve XR
node to the canvas.Change the following properties based on your measurements: Pitch Angle, Cell Width, Cell Height, Columns Count, Rows Count, Left Tilt/Roll and Right Tilt/Roll, Height Offset, Left Point and Right Point, Cell Resolution, Canvas Resolution.
Duplicate the modified
Curve XR
node.Connect the
RealityCamera0.Scene
output of theUE5
node toInner Frustum View
of theCurve XR
node.Connect the
RealityCamera1.Scene
output of theUE5
node toOuter Frustum View
of theCurve XR
node.
Preparing Inner Frustum Track
Create
Add Track
node.Connect the
Track
output ofXync
node to theX
input of theAdd Track
node.

Expand the
Y
property and change theFOV
property to 10.Connect the
Z
output of theAdd Track
node intoInner Frustum Track
input pin of theCurve XR
node.
Pan, tilt, and roll can now be performed independent of zoom level without causing collisions.
Preparing Outer Frustum Track

Create a
Break
node.Connect the
Track
output ofXync
node intoBreak
node’sInput
pin. Now we have access to Track data. For more details, see Dynamic Nodes.Create a
Make Track
node.Connect every
Break Track
node’s output to the matching inputs of theMake Track
node, except forRotation
andfov
pins.
Now:

Frame the LED screen with your studio camera and keep the zoom level at zero, as illustrated above.

Create an
Add f32
node.Connect the
fov
output of theBreak
node into theX
input of theAdd f32
node.Connect the
Z
output of theAdd f32
node to thefov
input of theMake Track
node.
Disconnect the
fov
output of theBreak
node from theX
input of theAdd f32
node.


Create an
Add vec3
node and connect itsZ
output toRotation
input of theMake Track
node.Connect the
rotation
output pin of theBreak Track
toX
input of theBreak
node.Disconnect the
Z
output of theAdd vec3
node to thefov
input of theMake Track
node.Connect the
Canvas
output of theCurve XR
node toAJAOut
, as illustrated above.

Our scene is successfully projected on the Curved LED.
