XR Wall - Digital Twin XR

Rendering XR Walls
Showing Pixotope World settings > XR

With XR you can extend your physical set beyond its borders or create a virtual window into another world. This is done by rendering the virtual scene onto for example LED screens using the perspective of the camera.

The Digital Twin XR actor allows to generate your physical setup using XR walls
- Automatic Digital Twin using Pixotope Tracking
- Manual Twin
The XR Wall actor displays the physical LED screen within the virtual environment
- It renders the off axis texture instead of regular fill
- One XR wall usually represents a single LED tile

XR Wall settings

Render to Output	Enable XR rendering for this wall
Output position	Choose how to place this XR Wall on the render output. Options are Full screen One of the four quadrants (Upper left, Upper right, Lower left, Lower right) Custom - see Custom Output Position Min and Max
Output	The name of the Output routed to this machine, onto which the XR Wall should be rendered to. Internal Buffers can be used for visualizing while there are no outputs routed yet.
Visualize	Preview the output directly on the XR wall (WYSIWYG)
Add Border	Renders a border around the XR wall in the viewport
Custom Output Position Min/Max	When the Output position is set to "Custom", use these parameters to specify the exact position of the XR Wall on the render output.
Flip XAxis/YAxis	Flips the X/Y axis of the output
Machines	Entering one or more windows machine names, enables selective rendering for an XR wall, so it only renders on the specified machines.
Color grading	Compensate for color discrepancies of the physical planes.

Outside Camera View	Choose the outside camera frustum rendering depending on your needs Render a custom color Renders a custom color Render extended view (optimized) Renders an extended view of the camera view (inner frustum) Render separate view Renders a separate view using the XROutsideFrustumPoint’s viewpoint Choose this option, if you need a static outside frustum for lighting and reflections. The XROutsideFrustumPoint actor can be found next to the TrackedCamera under the CameraRoot.
Sample Outside Frustum Color	Used when Outside Camera View is set to Render Color Color to use when trying to sample outside of frustum view
Render Outside Type	Used when Outside Camera View is set to Render Separate View Auto Capture - renders an expanded view (180º) Cube - renders the six sides of a cube (360º)
Auto Capture Optimize Aspect Ratio Auto Capture Size X Auto Capture Size Y	Used when Outside Camera View is set to Render Separate View Set a specific render resolution Optimize Aspect Ratio - when enabled, Size Y (output height) will be calculated based on the output width and its aspect ratio Size X - specify output width Size Y - specify output height
Input Export outside frustum	Use to render the outside frustum on a separate machine. Enable Export outside frustum on one machine Choose it as an Input on the other machine
Update Frequency Of Outside Camera View	Used when Render Outside Type is set to Cube Lower values mean better FPS in outside frustum capture but higher performance demands. 1 = update every frame, 5 = update disabled
Use Only Outside Camera View Rendering	Use the Outside Camera View rendering even inside the camera view (frustum). Reduces the quality but removes any seams. Mostly useful for testing
Use Uniform Color for Inner Frustum Inside Frustum Color	Set a static color for the inside camera view allowing for post production workflows.
XR Overscan	Blends between inside and outside camera view. 1 = no blend
Disable Custom Depth	Gain performance by disabling Custom Depth rendering (disables AR and VS)
Disable Motion Blur In XR	Disable Motion Blur when outputting
Disable Tonemapper	Checked by default as one usually does not want tone mapping on XR Walls. The tone mapping is handled by the display gamma of the output device.
Calibration mode	Customize the AR/XR colors used in the Calibrate Display Mode. Learn more about how to Check alignment
Advanced
XR From Current Camera	Uses the current camera position to project XR. Enable this when using virtual camera moves

Auto Algorithm	Algorithm used to find the best viewing angle when using Automatically Optimize Camera Rotation and FOV
Use Center	If enabled, only the XR wall centers are used instead of the corners to find the best viewing angle
Use Roll	If enabled, the camera is also rotated around its X axis. By default Automatically Optimize Camera Rotation and FOV only rotates the camera around Y and Z.
Optimize Aspect Ratio	Also optimizes the aspect ratio when using Automatically Optimize Camera Rotation and FOV
Instant Adjustment	If enabled, the camera is moved instantly to the position. Needs to be enabled when using Camera input switching.
Roll Step	Defines the accuracy of the roll, if Use Roll is enabled
Use Zoom Momentum	To avoid rapid zoom changes, a momentum to the zoom is added. Needs to be disabled when using Camera input switching.
Zoom Momentum	Speed of zoom changes, if Use Zoom Momentum is enabled
