Disparity Maps without Ocula

In this video I will demonstrate how, with built in nuke tools, you can generate a disparity map for a stereo plate without the necessity of Ocula. This disparity map can be used for everything related to stereo compositing outside of the use of the Ocula plugins. This includes the correlating of roto's, transforms, tracker data, and paint strokes, all or which can be accomplished with this generated disparity map.
