<brief_description>
|
|
A modification that uses CCDIK to manipulate a series of bones to reach a target.
|
|
</brief_description>
|
|
<description>
|
|
This [SkeletonModification3D] uses an algorithm called Cyclic Coordinate Descent Inverse Kinematics, or CCDIK, to manipulate a chain of bones in a Skeleton so it reaches a defined target.
|
|
CCDIK works by rotating a set of bones, typically called a "bone chain", on a single axis. Each bone is rotated to face the target from the tip (by default), which over a chain of bones allow it to rotate properly to reach the target. Because the bones only rotate on a single axis, CCDIK [i]can[/i] look more robotic than other IK solvers.
|
|
[b]Note:[/b] The CCDIK modifier has [code]ccdik_joints[/code], which are the data objects that hold the data for each joint in the CCDIK chain. This is different from a bone! CCDIK joints hold the data needed for each bone in the bone chain used by CCDIK.
|
|
CCDIK also fully supports angle constraints, allowing for more control over how a solution is met.

|
|
Sets whether the CCDIK joint at [code]joint_idx[/code] uses an inverted joint constraint.
|
|
An inverted joint constraint only constraints the CCDIK joint to the angles [i]outside of[/i] the inputted minimum and maximum angles. For this reason, it is referred to as an inverted joint constraint, as it constraints the joint to the outside of the inputted values.

When true, the CCDIK algorithm will perform a higher quality solve that returns more natural results. A high quality solve requires more computation power to solve though, and therefore can be disabled to save performance.
