‌Details of Lock Modes ‌

There are quite a few different constraint (lock) modes that can be selected from the drop-down list. Despite the fair number of different cases, they all can be broken down to answering two simple questions: (1) which coordinates (X, Y, and/or Z) of the tracker should be locked, and (2) to what values.

The first question can have one of eight different answers: all the combinations of whether or not each of the three coordinate axes is locked, ranging from none (Unconstrained) to all (Lock Point). Rather than listing each of the combinations of which axes are locked, the list really talks about which axis is NOT locked. For example, an X Axis lock really locks Y and Z, leaving X unconstrained. Locking to the XZ plane actually locks only Y. The naming addresses WHAT you want to do, not HOW SynthEyes will achieve it.

The second question has three possible answers: (a) to zero, (b) to the corresponding “Seed and Lock” spinner, or (c) the corresponding coordinate from the tracker assigned as the Target Point. Answer (c) is automatically selected if a target point is present, while (a) is selected for “On” lock types, and (b) for “Any” lock types. Use the Any modes when you have some particular coordinates you want to lock a tracker to, for example, if a tracker is to be placed 2 units above the ground plane.

Watch Out! If you select several trackers, some with targets, some without, the lock type list will be empty. Either select fewer trackers, or right-click the Target button to clear the target tracker setting from all selected trackers.

Here’s the total list:
