Thread-safe cache for accessing query objects for evaluating skeletal data.
This provides caching of major structural components, such as skeletal topology. In a streaming context, this cache is intended to persist.
| USDSKEL_API bool ComputeSkelBinding | ( | const UsdSkelRoot & | skelRoot, |
| const UsdSkelSkeleton & | skel, | ||
| UsdSkelBinding * | binding, | ||
| Usd_PrimFlagsPredicate | predicate | ||
| ) | const |
Compute the bindings corresponding to a single skeleton, bound beneath skelRoot, as discovered through a traversal using predicate.
Skinnable prims are only discoverable by this method if Populate() has already been called for skelRoot, with an equivalent predicate.
| USDSKEL_API bool ComputeSkelBindings | ( | const UsdSkelRoot & | skelRoot, |
| std::vector< UsdSkelBinding > * | bindings, | ||
| Usd_PrimFlagsPredicate | predicate | ||
| ) | const |
Compute the set of skeleton bindings beneath skelRoot, as discovered through a traversal using predicate.
Skinnable prims are only discoverable by this method if Populate() has already been called for skelRoot, with an equivalent predicate.
| USDSKEL_API UsdSkelAnimQuery GetAnimQuery | ( | const UsdSkelAnimation & | anim | ) | const |
Get an anim query corresponding to anim.
This does not require Populate() to be called on the cache.
| USDSKEL_API UsdSkelAnimQuery GetAnimQuery | ( | const UsdPrim & | prim | ) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
| USDSKEL_API UsdSkelSkeletonQuery GetSkelQuery | ( | const UsdSkelSkeleton & | skel | ) | const |
Get a skel query for computing properties of skel.
This does not require Populate() to be called on the cache.
| USDSKEL_API UsdSkelSkinningQuery GetSkinningQuery | ( | const UsdPrim & | prim | ) | const |
Get a skinning query at prim.
Skinning queries are defined at any skinnable prims (I.e., boundable prims with fully defined joint influences).
The caller must first Populate() the cache with the skel root containing prim, with a predicate that will visit prim, in order for a skinning query to be discoverable.
| USDSKEL_API bool Populate | ( | const UsdSkelRoot & | root, |
| Usd_PrimFlagsPredicate | predicate | ||
| ) | const |
Populate the cache for the skeletal data beneath prim root, as traversed using predicate.
Population resolves inherited skel bindings set using the UsdSkelBindingAPI, making resolved bindings available through GetSkinningQuery(), ComputeSkelBdining() and ComputeSkelBindings().
