Aim

Aimik solver is a correction to the CCD algorithm (Cyclic coordinate decent cycle coordinate descent algorithm). By rotating the skeleton hierarchy, the transform of the Child skeleton after the target is targeted is determined.

It is different from the setlookatposition and lookatik functions of the built-in animator, because it can perform precise target conversion for inconsistent hierarchical spindle. (Because it is able to accurately aim transforms that are not aligned to the main axis of the hierarchy.)

Aimik's ability to relocate a role animation produces a very stable and natural look, so it has a huge potential in the weapon targeting system. With aimik, we can aim at the target by shifting a single forward aiming posture or animation, even if the target is almost behind the role. It is only a 180-degree offset to the singularity of the Quaternary element, and solver does not know where to turn the spine. Like lookatik, aimik provides a clampweight attribute to avoid singularity issues.

Aimik is also applicable to rotation restrictions. However, it is easier to block than other constraints, and the chain should be highly restrictive.

With high-speed and high-precision, aim must keep the target location and aiming transform in a safe range. If the distance to traget is less than the distance to aiming transform, solver will try to roll itself and may not produce the expected results.
