Overview

Skeletons, poses, skinning and clips.

A skeleton is a joint hierarchy over caller slices. Joint clips key each joint's rotation and translation at an authored rate; playback samples them at any time, optionally held on steps; poses blend and crossfade; forward kinematics composes local transforms into world ones; rigid skinning moves each vertex with its one joint; and part slots swap what a joint draws. None of these allocate: storage is the caller's, sized from joint, key and vertex counts.

articulated is a rig of handles driven by revolute and prismatic coordinates, with a point Jacobian and collision proxies, posed through the same forward kinematics. curve holds parameter clips, which key plain values rather than joints.

Namespaces

Public namespaces.

• articulated: An articulated rig: handles joined by revolute and prismatic coordinates, with a point Jacobian and collision proxies on top.
• curve: Parameter curves: clips of plain values that drive shape and material parameters, with a mixer, a state machine, a blend space and notify tracks over them.
• part: Parts: what each joint draws.
• blend: Blending two poses, and crossfading from one clip to another.
• skin: Rigid skinning: every vertex follows exactly one joint.

Values and defaults

Public values and defaults.

• max_joints: The parent of a root joint.
• no_parent: The parent of a root joint.
• ones: Poses a second for animation on ones and on twos, at 24 frames a second.
• twos
