Basic Node Setup
Disparity To Z takes a 3D camera and stereo images containing a disparity channel as inputs.
The output is an image with a newly computed Z channel.
A Disparity to Z node creates an image with a Z channel
Inspector
Controls Tab
In addition to outputting Z values in the Z channel, this tab promotes the color channels to
float32 and outputs the Z values into the color channels as {z, z, z, 1}. This option is useful to get
a quick look at the Z channel.
NOTE: Z values are negative, becoming more negative the further you are from the
camera. The viewers only show 0.0 to 1.0 color, so to visualize other data it has to be
converted via a normalization method to fit in a display 0-1 range. To do this, right-click
in the viewer and choose Options > Show Full Color Range.
Output Z to RGB
Rather than keeping the Z values within the associated aux channel only, they will be copied
into the RGB channels for further modification with any of Fusion’s nodes.
Refine Z
The Enable checkbox refines the depth map based upon the RGB channels. The refinement
causes edges in the flow to align more closely with edges in the color channels. The downside
is that unwanted details in the color channels start to show up in the flow. You may want to
experiment with using this option to soften out harsh edges for Z-channel post effects like
depth of field or fogging.
