Transforming the Scene Manually

In addition to defining the ground plane, axes, and origin automatically, you can manually adjust the scene using the Scene tab's Scene Transform controls. These controls operate in exactly the same way as other transform tools in Nuke.

To transform a scene, use the following controls:

• rotation order - set the operation order for rotations from the dropdown menu which displays all the possible axial combinations.

• translate - set translate values for the scene. You can adjust translate values by clicking and dragging the axis in the 3D viewer.

• rotate - set values to rotate your camera or use Ctrl/Cmd to rotate the camera in the Viewer.

• scale - set scale values on individual axes, rather than uniformly or use Ctrl/Cmd+Shift to scale the camera in the Viewer.

NOTE:  This control is only displayed if you've scaled the scene on individual axes.

• uniform scale - set a scale for your scene. You can also scale the scene using actual measurements taken on set, see Using Scene Constraints for more information.

Alternatively, you can also use the Local matrix to perform transforms on your scene.

NOTE:  The World matrix is read-only and cannot be edited.

Transforming Using Channel Files

Channel files contain a set of cartesian coordinates for every frame of animation in a given shot. You can create and export them using Nuke or 3D tracking software, such as 3D-Equalizer, Maya, or Boujou.

You can transform the scene using channel files by clicking the button:

• Import chan file - import a channel file and transform the input object according to the transformation data in the channel file.

• Export chan file - export the translation parameters that you’ve applied to the input object as a channel file. This is a useful method of sharing setups between artists.

Transforming Using Snap To Position

The Snap To menu allows you to match the position, orientation, and scale of existing points.

Select the required points and then click the button:

• Match selection position - the scene is snapped to a new position depending on the points selected.

• Match selection position, orientation - the scene is snapped to a new position and orientation depending on the points selected.

• Match selection position, orientation, size - the scene is snapped to a new position, orientation, and size depending on the points selected.
