Detailed Description

This class specializes a node attribute to represent the elements forming "bone" chains.

The FbxSkeleton name of the class comes from the analogy with the human body skeletal structure. In fact, an object of this type is nothing more than a transform node with special properties that are useful for its graphical representation and during IK/FK and skin deformation computations. Typically, a scene will contain chains of FbxSkeleton node attributes that, together, form a skeleton segment. For instance, the representation of the leg of a character can be achieved using one parent node with the attribute eRoot, followed by one child (femur) of type eLimb, this child having a child also (tibia) of the same type. Finally, terminated with a last node attribute of type eEffector (ankle).

Examples:

ExportScene01/main.cxx, ExportScene05/main.cxx, ImportScene/DisplaySkeleton.cxx, and ViewScene/DrawScene.cxx.

Member Enumeration Documentation

enum EType

Skeleton types.

Remarks:

eEffector is synonymous to eRoot.

The eLimbNode type is a bone defined uniquely by a transform and a size value while

the eLimb type is a bone defined by a transform and a length.

FbxPropertyT<FbxDouble> LimbLength

Search for all occurrences

This property handles the skeleton limb length.

To access this property do: LimbLength.Get(). To set this property do: LimbLength.Set(FbxDouble).

FbxSkeleton is a node attribute and it will be attached to a FbxNode which represents the transform. Given a chain of skeleton nodes the parent and child skeletons will be attached to a parent node and a child node. The orientation of the limb is computed from the vector between the parent and child position (from parent to child). The LimbLength represents the proportion of the parent node's position to the child node's position which is used to compute the actual limb length. The default value of 1.0 means the LimbLength is equal to the length between the parent and child node's position. So if the value is 0.5, it means the LimbLength will be half of the length between the parent and child node's position.
