World Locking Tools for Unity

Increased anchor stability

Moving the creation point for anchors to the camera position allows higher fidelity and reduces impact of tracking errors.

To help avoid the inconvenience of anchor display (for diagnostics/debugging) at eye level, which can be disconcerting, an option has been added to the AnchorGraphVisual to displace anchor visuals vertically. Positive displacement raises them, negative lowers them. The default value of -1 (meter) puts the anchor visuals at the same height as previously, even though the anchors are now at eye level. A displacement of zero shows actual anchor positions.

Option to preserve gravity vector

Noisy tracking can cause the FrozenWorldEngine to introduce non-zero pitch and roll to the camera, causing a misalignment of the Y-axis to the physical gravity vector. The World Locking Context has a new option, under Camera Transform Links, of "No Pitch And Roll". This will zero out any such spurious pitch and roll introduced, limiting the camera correction to translation and yaw rotation about the horizontal plane.

Fix compatibility issue with ASA v2.11

A workaround for an issue with earlier versions of ASA is not needed with ASA v2.11, and in fact causes incorrect behavior. This has been fixed.
