Stereoscopic Workflows
Disparity is the difference between the left and right image. The Disparity map is used by nodes
to align and massage the stereo pair of images.
The Disparity node analyzes a stereo pair of
images and generates an X&Y disparity map.
The workflow is to load a left and right stereo image pair and process those in the Disparity
node. Once the Disparity map is generated, other nodes can process the images.
TIP: When connectng stereo pairs in the node tree, make sure that the left and right
images are connected to the left and right inputs of the Disparity node.
Disparity generation, like Optical Flow, is computationally expensive, so the general idea is that
you can pre-generate these channels, either overnight or on a render farm, and save them into
an EXR sequence.
The toolset is designed around this philosophy.
