*
|
|
* A group of objects that receives a shared animation state.
|
|
*
|
|
* Usage:
|
|
*
|
|
* - Add objects you would otherwise pass as 'root' to the
|
|
* constructor or the .clipAction method of AnimationMixer.
|
|
*
|
|
* - Instead pass this object as 'root'.
|
|
*
|
|
* - You can also add and remove objects later when the mixer
|
|
* is running.
|
|
*
|
|
* Note:
|
|
*
|
|
* Objects of this class appear as one object to the mixer,
|
|
* so cache control of the individual objects must be done
|
|
* on the group.
|
|
*
|
|
* Limitation:
|
|
*
|
|
* - The animated properties must be compatible among the
|
|
* all objects in the group.
|
|
*
|
|
* - A single property can either be controlled through a
|
|
* target group or directly, but not both.

|
|
* ModelGraft
|
|
*
|
|
* This is a coordination primitive between a scene graph as represented by the
|
|
* output for Three.js' GLTFLoader and a counterpart 3DOM facade. Since this is
|
|
* the Three.js-specific implementation of the facade, the input is a GLTF-like
|
|
* object whose keys refer to Three.js-specific constructs (e.g., gltf.scene is
|
|
* a THREE.Scene).
|
|
*
|
|
* When created, the ModelGraft produces a Model that can be traversed and
|
|
* manipulated to mutate the Three.js scene graph synchronously (but
|
|
* indirectly). The benefit of this is that mutations to the Three.js scene can
|
|
* be performed in a Three.js-agnostic fashion that is potentially portable to
|
|
* alternative rendering backends.
|
|
*
|
|
* The scene graph representation produced by the ModelGraft is designed to
|
|
* match the structures described in the glTF 2.0 spec as closely as possible.
|
|
* Where there are deviations, it is usually for the purpose of making
|
|
* synchronization easier, or else for ergonomics. For example, in glTF 2.0, the
|
|
* graph is a series of flat arrays where nodes cross-reference each other by
|
|
* index to represent hierarchy, but in a Model nodes have array members
|
|
* containing refrences to their hierarchical children.
|
|
*
|
|
* An important goal of ModelGraft is to enable a scene in one JavaScript
|
|
* context to be manipulated by script in a remote context, such as a distant
|
|
* worker thread or even a different process. So, every node in the graph
|
|
* is able to be serialized, and the serialized form includes an ID that is
|
|
* locally unique to the ModelGraft instance that the node came from so that
|
|
* the remote context can refer back to it. A ModelGraft can be thought of as
|
|
* the host execution context counterpart to the ModelKernel in the scene graph
|
|
* execution context.
