Adding Vertices
To produce more accurate geometry, especially with natural ground surfaces, you can increase the mesh density with the Track menu’s Add many trackers dialog, rapidly creating additional trackers after an initial auto-track and solve has been performed, but before using Convert To Mesh.
Especially for man-made objects, there may not be a tracker where you need one to accurately represent the geometry. SynthEyes uses spot tracking which favors the interior of objects, not the corners, which are less reliable due to the changing background behind them. So even if you used auto-tracking and the Add many trackers dialog, you will probably want to add additional supervised trackers for particular locations.
To produce additional detail trackers, especially at the corners of objects, the offset tracking capability can be very helpful, which is an advanced form of supervised tracking. With offset tracking, you can use existing supervised trackers to add new nearby trackers on corners and fine details, without too much time. You can clone off a number of offset trackers to handle small details in a building, for example. But beware! The accuracy of an offset tracker is entirely determined by the quality of the offsets you build; if you do too quick a job, the offset tracker will not be accurate in 3-D. Offset tracking works better when the camera motion is simple, even if it is bumpy; for example, a dolly to the right.
Whether you use Add Many Trackers, create new supervised trackers, or clone out new offset trackers, you can use Convert to Mesh to add them to the existing edit mesh if you are auto-triangulating.
