Uses the XYZ data in the PointMap node of a stereo camera and computes normals for each point. The resulting normals are written into a separate XYZ float image at Images/Normals. Each XYZ vector is normalized to length 1 and oriented towards the camera’s projection center. In degenerate cases (e.g. on depth discontinuities) the normals might point away from the camera.
The normal map coordinates are represented in the same world/workspace coordinate system as the PointMap itself.
