Selected trackers are projected onto the specified mesh at a specified frame. The position where each tracker is located on the mesh becomes its seed position. This phase can be used when an object mesh can be position correctly on a single frame, or the camera can be positioned on a single frame, to generate a set of seed coordinates for a solve using "From Seed Points" mode. To assist that, the tracker's host object is set to "From Seed Points" solving mode.
The affected trackers are those that are selected at the input to the phase. All selected trackers must be attached to the same camera or moving object. That camera, or the moving object's camera, is used as the vantage point to project the trackers from 2D into 3D.
Each selected tracker is made to be a seed tracker.
If "Make pegged" is checked, the tracker is marked to be pegged, so that those coordinates will be matched exactly in any subsequent solve with the Constrain checkbox on.
If "Make solved" is checked, the tracker is marked to be solved at those coordinates as
well.
