Expand description

Data structures and methods for dealing with armatures.

@see https://docs.blender.org/manual/en/dev/modeling/armature/introduction.html - Armature Introduction

Structs§

Action: A set of keyframes along with metadata such as pose markers.
ActionKeyframes: All of the keyframes in an action.
BlenderArmature: All of the data about a Blender armature that we’ve exported from Blender. A BlenderArmature should have all of the data that you need to implement skeletal animation.
BoneKeyframe: The transformation for a bone at a particular time
BoneKeyframes: The keyframes for the transformations for a bone
CoordinateSystem: A coordinate system is used to make sense of coordinates.
FrameOffset: Describes some number of frames to offset from some other frame. Useful for sampling keyframes.
Keyframe: The pose bones at an individual keyframe time
SampleDesc: Describes how to sample animation keyframes
SortedKeyframes: Keyframes sorted in ascending frame order

Axis
BlenderError: Something went wrong in the Blender child process that was trying to parse your armature data.
Bone: A bone in an armature. Can either be a dual quaternion or a matrix. When you export bones from Blender they come as matrices - BlenderArmature lets you convert them into dual quaternions which are usually more favorable for when implementing skeletal animation with rigid transformations.
FlattenArmatureError: An error when trying to flatten your exported data across multiple files into one HashMap of armature name to armature data.
Hand: Represents the orientation of the coordinate system using the right hand rule.
JointIndicesRef: The joints to sample.

blend_towards_bones: Blend from the start bones towards the ending bones.
flatten_exported_armatures: Convert ArmatureeshByFilename into a HashMap<ArmatureName, BlenderArmature> that flattens all of the armatures across all of the files into one HashMap.
get_surrounding_keyframes: If you’re sampling frame 1.5 and there are three keyframes - 0, 2, 3 the surrounding keyframes are 0 and 2.
interpolate_bone: Interpolate from the start to the end bone using the given amount between [0.0, 1.0] inclusive.
interpolate_dual_quats: Interpolate from the start to the end bone using the given amount between [0.0, 1.0] inclusive.
linear_200_milliseconds: Returns 0.0 if no time has elapsed. Returns 0.5 if 100 milliseconds have elapsed. Returns 1.0 if >= 200 milliseconds have elapsed
parse_armatures_from_blender_stdout: Given a buffer of standard output from Blender we parse all of the armature JSON that was written to stdout by blender-armature-to-json.py.
