O_NewView

Use the O_NewView node to reconstruct a view – either left or right – using the pixels from the other view. For example, you can choose to reconstruct the left view using the pixels from the right view. This can be useful if you want to manipulate one view (with a gizmo, node, or graphics editor for example) and replicate the changes into the other view.

Inputs and Controls

Connection Type	Connection Name	Function
Input	CleanPlate	A clean background plate used to fill areas of occlusion when Correction is set to Use CleanPlate. NOTE: If no image is connected, a Channels missing at CleanPlate input. Please connect RGB input to CleanPlate error is displayed.
Source	A stereo pair of images. NOTE: If disparity channels aren’t embedded in the images, you should add an O_DisparityGenerator node after the image sequence. O_NewView also requires an O_OcclusionDetection node upstream.

Local GPU	gpuName	N/A	Displays the GPU used for rendering when Use GPU if available is enabled. Local GPU displays Not available when: • Use CPU is selected as the GPU Device in the Preferences. • no suitable GPU was found on your system. • it was not possible to create a context for processing on the selected GPU, such as when there is not enough free memory available on the GPU. You can select a different GPU Device, if available, by navigating to the Preferences and selecting an alternative from the GPU Device dropdown. NOTE: Selecting a different GPU requires you to restart Nuke before the change takes effect.
Use GPU if available	useGPUIfAvailable	enabled	When enabled, rendering occurs on the Local GPU specified, if available, rather than the CPU. The output between the GPU and CPU is identical, but using the GPU can significantly improve processing performance. NOTE: Enabling this option with no local GPU allows the script to run on the GPU whenever the script is opened on a machine which does have a GPU available. You should also select this if you wish to render from the command line with the --gpu option. The GPU processing also requires certain NVIDIA GPUs and CUDA drivers. For more information on the minimum requirements, please refer to the Nuke Release Notes available in Help > Release Notes.
Views to Use	viewPair	Dependent on Source	Sets the two views you want to use to create the new view. These views will be mapped for the left and right eye.
View to Build	viewRebuilt	Left from Right	Select the two views you want to use to generate the new view. These views are mapped for the left and right eye.
Pass through other view	passThrough OtherView	enabled	When enabled, output both the new, rebuilt view and the original source view. When disabled, only the new view is output.
Occlusions
Output occlusions to alpha	outputOcclusions ToAlpha	disabled	When enabled, output the occlusions to the alpha channel. Occlusions occur when some pixels are not visible in the source view, and therefore cannot be used to create the new view. You can use the alpha channel as an overlay to determine where the occlusion correction is applied.
Correction	occlusionCorrection	Use original	Determines how occluded regions are dealt with: • Use original - Select this option to retain the original view in the occluded regions. For example, if you are using the original left view to build a new right view, the original right view is retained in the occluded regions to help build the new right view. • Expand foreground - Select this option to fill occluded regions by expanding the surrounding area from the original source view. For example, if you are using the original left view to build a new right view, the foreground of the original left view is expanded to help build the new right view. NOTE: Expanding the foreground may offset the edges. • Use CleanPlate - Select this option to fill occluded areas using a clean background which is connected using the CleanPlate input. NOTE: If no image is connected, a Channels missing at CleanPlate input. Please connect RGB input to CleanPlate error is displayed. • None - Select this option to avoid filling the occluded regions.
Edges
Output edges to alpha	outputEdgesTo Alpha	disabled	When enabled, output the edges to the alpha channel. Use the alpha channel as an overlay to determine where the edge correction is applied.
Correction	edgeCorrection	Match original	Determine how image edges at depth boundaries are handled: • Match original - Select this option to match the appearance of the original view at the edges. For example, if you are using the original left view to build a new a right view, the edges are matched from the original right view to help build the new right view. • Match foreground - Select this option to match the edges from the original source view that was used to build the new view. For example, if you are using the original left view to build a new right view, the edges are matched from the original left view to help build the new right view. • None - Select this option to avoid applying edge correction.
Adjust Edges	adjustEdges	0	Sets the extent of the region where the edge correction is applied. To blend the correction into the background, use a positive value. To restrict the correction to the edges, use a negative value.
