A node containing a bone hierarchy, used to create a 3D skeletal animation.

[Skeleton3D] provides an interface for managing a hierarchy of bones, including pose, rest and animation (see [Animation]). It can also use ragdoll physics.
2023-05-27 06:36:15 +02:00
The overall transform of a bone with respect to the skeleton is determined by bone pose. Bone rest defines the initial transform of the bone pose.
Note that "global pose" below refers to the overall transform of the bone with respect to skeleton, so it is not the actual global/world transform of the bone.

New and improved IK system for Skeleton3D
This PR and commit adds a new IK system for 3D with the Skeleton3D node
that adds several new IK solvers, as well as additional changes and functionality
for making bone manipulation in Godot easier.
This work was sponsored by GSoC 2020 and TwistedTwigleg
Full list of changes:
* Adds a SkeletonModification3D resource
* This resource is the base where all IK code is written and executed
* Adds a SkeletonModificationStack3D resource
* This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node
* Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in it's own file
* Several changes to Skeletons, listed below:
* Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract
* So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone
* Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain
* Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them.
* New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D
* Added functions for getting the forward position of a bone
* BoneAttachment3D node refactored heavily
* BoneAttachment3D node is now completely standalone in its functionality.
* This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes
* BoneAttachment3D now can be set either using the index or the bone name.
* BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility
* BoneAttachment3D now shows a warning when not configured correctly
* Added rotate_to_align function in Basis
* Added class reference documentation for all changes

New and improved IK system for Skeleton3D
This PR and commit adds a new IK system for 3D with the Skeleton3D node
that adds several new IK solvers, as well as additional changes and functionality
for making bone manipulation in Godot easier.
This work was sponsored by GSoC 2020 and TwistedTwigleg
Full list of changes:
* Adds a SkeletonModification3D resource
* This resource is the base where all IK code is written and executed
* Adds a SkeletonModificationStack3D resource
* This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node
* Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in it's own file
* Several changes to Skeletons, listed below:
* Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract
* So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone
* Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain
* Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them.
* New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D
* Added functions for getting the forward position of a bone
* BoneAttachment3D node refactored heavily
* BoneAttachment3D node is now completely standalone in its functionality.
* This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes
* BoneAttachment3D now can be set either using the index or the bone name.
* BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility
* BoneAttachment3D now shows a warning when not configured correctly
* Added rotate_to_align function in Basis

Sets the global pose transform, [param pose], for the bone at [param bone_idx].
[param amount] is the interpolation strength that will be used when applying the pose, and [param persistent] determines if the applied pose will remain.
2023-02-11 17:18:33 +01:00
[b]Note:[/b] The pose transform needs to be a global pose! To convert a world transform from a [Node3D] to a global bone pose, multiply the [method Transform3D.affine_inverse] of the node's [member Node3D.global_transform] by the desired world transform.
New and improved IK system for Skeleton3D
This PR and commit adds a new IK system for 3D with the Skeleton3D node
that adds several new IK solvers, as well as additional changes and functionality
for making bone manipulation in Godot easier.
This work was sponsored by GSoC 2020 and TwistedTwigleg
Full list of changes:
* Adds a SkeletonModification3D resource
* This resource is the base where all IK code is written and executed
* Adds a SkeletonModificationStack3D resource
* This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node
* Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in it's own file
* Several changes to Skeletons, listed below:
* Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract
* So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone
* Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain
* Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them.
* New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D
* Added functions for getting the forward position of a bone
* BoneAttachment3D node refactored heavily
* BoneAttachment3D node is now completely standalone in its functionality.
* This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes
* BoneAttachment3D now can be set either using the index or the bone name.
* BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility
* BoneAttachment3D now shows a warning when not configured correctly
* Added rotate_to_align function in Basis
* Added class reference documentation for all changes

Remove animation 3D transform track, replace by loc/rot/scale tracks.
* `Animation.TYPE_TRANSFORM3D` track is gone.
* Added POSITION_3D, ROTATION_3D, SCALE_3D tracks.
* GLTF2, Collada, FBX importers will only import the track types found.
* Skeleton3D bone poses are now Pos/Rot/Scale, pose matrix removed.
* AnimationPlayer and AnimationTree animate these tracks separately, only when found.
* Removed BakeReset code, is useless with these changes.
This is the first in a series of commits designed to make the animation system in Godot more useful, which includes:
* Better compatibility with Autodesk products
* Better reusability of animations across models (including retargeting).
* Proper animation compression.
* etc.
*Note* GLTF2 animation saving went broken with this PR, needs to be fixed in a subsequent one.

If you follow the recommended workflow and explicitly have [PhysicalBoneSimulator3D] as a child of [Skeleton3D], you can control whether it is affected by raycasting without running [method physical_bones_start_simulation], by its [member SkeletonModifier3D.active].
However, for old (deprecated) configurations, [Skeleton3D] has an internal virtual [PhysicalBoneSimulator3D] for compatibility. This property controls the internal virtual [PhysicalBoneSimulator3D]'s [member SkeletonModifier3D.active].
