WARNING: Draft API, this design is not fixed and may change in the future.
At this point, we don't support multi-axis joints (e.g. spherical, D6).
Applied to a Physics Joint that must be part of an articulation, e.g. PhysicsRevoluteJoint or PhysicsPrismaticJoint.
A tendon axis is part of a fixed tendon and contributes to the tendon length via the position of its associated articulation joint axis and the gearing attribute. The tendon applies spring-damper forces to the articulation links, scaled by the force coefficient, that aim to maintain constraints on the tendon lengths.
A joint may have multiple tendon axes that belong to distinct fixed tendons; therefore, the fixed-tendon APIs are multi-apply and are grouped into tendons by their instance names.
Fixed tendons do not allow linking arbitrary joint axes of the articulation: The respective joints must all be directly connected to each other in the articulation structure, i.e. each of the joints in the tendon must be connected by a single articulation link to another joint in the same tendon. This implies that fixed tendons can branch along with a branching articulation as well. In addition, the root tendon axis created by applying the PhysxTendonAxisRootAPI must be applied to the articulation joint that is the common ancestor of all joint axes in the fixed tendon.
In a future version, it will be possible to include multiple axes of a multi-axis joint (e.g. a spherical joint) in the fixed tendon by adding them to the axis token array, and setting their gearing and forceCoefficient accordingly in the respective float arrays (in the same order). Until then, the jointAxis token array is ignored, and only the first element of the gearing array is considered.

Returns the kind of schema this class belongs to.

static |
Applies this multiple-apply API schema to the given prim
along with the given instance name, name
.
This information is stored by adding "PhysxTendonAxisAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name
is 'instance1', the token 'PhysxTendonAxisAPI:instance1' is added to 'apiSchemas'.

Returns true if this multiple-apply API schema can be applied, with the given instance name, name
, to the given prim
.
If this schema can not be a applied the prim, this returns false and, if provided, populates whyNot
with the reason it can not be applied.
Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.
