User Manual

Camera
If multiple cameras are available in the connected Scene input, this drop-down menu allows
you to choose the correct camera needed to evaluate the Volume.
Instead of connecting a camera, position values can also be provided manually or by
connecting the XYZ values to other controls.
Translation Pick
Drag the Pick button into the viewer to select XYZ coordinates from any 3D scene or 2D image
containing XYZ values, like a rendered World Pass, to define the center of the camera.
When picking from a 2D image, make sure it’s rendered in 32-bit float to get full precision.
X, Y, Z Offset
These controls can be used to define the center of the camera manually or can be animated or
connected to other controls in Fusion.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other Position nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
Z to World Pos [Z2W]
The Z to World Position node
Z to World Pos Node Introduction
The Z to World Pos node is used to either generate a World Position Pass from a Z channel and
a 3D Camera or a Z channel from a World Position Pass and a 3D Camera.
Creating a World Position Pass from Z-depth can be useful when your 3D application is not
capable of creating a WPP.
It can also be used when a 3D-tracking software outputs a per-pixel Z-depth together with the
3D Camera. Thus, the Volume Mask and Volume Fog could be applied to real-world scenes.
The quality of the resulting WPP depends mainly on the quality of the incoming Z channel.
See the “WPP Concept” section for further explanation on how this technology works and to
learn about the required imagery.
