Animation system managing scene constraints pose-based caching PGPUB dup.
According to one implementation, an animation system includes a computing platform having a hardware processor and a system memory storing a software code. The hardware processor executes the software code to receive pose data including rig control values for multiple animation rigs, and to store the rig control values for each animation rig in respective rig control caches identified with the animation rig. The hardware processor also executes the software code to receive constraint data linking one animation rig to one rig control cache identified with any animation rig, receive change data for one rig control value of that linked animation rig, update the rig control value based on the change data, and clear the rig control cache linked with the updated animation rig. Thus, updating any rig control value of an animation rig results in clearing rig control caches linked with that animation rig.
BACKGROUND
In animation, a pose of an animation rig is defined by a collection of rig controls, which are typically the interactive handles or the keyable attributes of the animation rig. Those rig controls can be expensive to compute and are most efficiently accessed by caching their values in rig control caches. In the absence of scene constraints, the mapping of rig controls to rig control caches is typically one-to-one and self-contained within a single animation rig. As a result, when the animation of rig controls are modified in such cases, their corresponding rig control caches are easily reset.
However, when constraints are added to a scene, the mapping of rig controls to rig control caches ceases to be one-to-one, and the mapping frequently crosses animation rig boundaries. That is to say, when scene constraints are introduced, a single rig control may be mapped to multiple rig control caches of several different animation rigs. Consequently, the introduction of scene constraints makes it more difficult to determine what rig control caches should be reset and when those resets should occur. Moreover, the complexity produced by the introduction of scene constraints is compounded when the constraints relate the state of one animation rig to the rig control cache of another animation rig.SUMMARY
