Inputs

O_DepthToDisparity has the following inputs:

Camera

A Nuke stereo Camera node. This is the camera the scene was rendered with. In most cases, you would import this into Nuke from a third-party 3D application. For information on how to do this, see the Nuke User Guide.

In Nuke, a stereo camera can be either:

• a single Camera node in which some or all of the controls are split, or

• two Camera nodes (one for each view) followed by a JoinViews node (Views > JoinViews). The JoinViews node combines the two cameras into a single output.


A single Camera node with split controls.	Two cameras combined using Nuke’s JoinViews node.

Depth

This is a stereo pair of images (usually, a scene you’ve rendered from a 3D application). In the depth channel, there should be a z-depth map for each view.

Note: If this input is an .exr file, the z-depth map may already be embedded in the clip.

If you’re using another file format and have saved the depth map as a separate image, you can use a Nuke Shuffle node (Channel > Shuffle) to get the z-depth map in the depth channel of the Depth image. For information on how to do this, see the Nuke User Guide.
